Abstract

A downhole device comprising a novel apparatus and vibratory assemblage that initiates and maintains mechanical agitation within the horizontal section of a well bore by providing both low and high vibration, in multiple axes and planes, and through pulsing of high-pressure fluids within the confines of the apparatus and drilling pipe. Through the judicious and conservative use of fluids, the present invention provides both rotationally accelerated low and high vibration and high-intensity, directed and timed pressure to reduce the cumulative friction between the drill string and bottom hole assembly on a wellbore. Additionally, the present apparatus can be preprogrammed to respond to specific commands, in response to certain predetermined conditions, to stop and start functioning at various times throughout the drilling process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0047] The present invention allows for pipe vibration to be applied to any joint, seamless, coiled or snubbed pipe configuration whether threaded or not. The present invention allows for pipe to be delivered to lateral sections of a well with the aid of vibratory tools that excite pipe in multiple axes, This agitation process is achieved by pumping fluids through a series of ported discs and turbine-exhibiting shafts that oscillate the vibratory assembly 100 and creates both vibration of the pipe and fluid pulses within the pipe to educe friction between similar and dissimilar materials.

[0048] As depicted in FIG. 1, the vibratory assembly 100 that is the present system uses a series of valves and rotating turbines wherein the vibratory assembly 100 induces vibration when fluid is pumped down the drill string and into the vibratory assembly 100 thereby turning the shaft 36, via finned turbines 32,34, that provide rotational movement, as well as pressurized fluid flow to a rotationally operable exit port 56, to create a variable high to low range intensity vibration combined with a high intensity fluid jet ahead of the assembly. This turbine-powered, rotationally operable shaft 36, which may include an integrated offset weight (not shown), causes fluid-controlled circular rotation in the assembly 100 to induce vibration on the first axis. In both the upper turbine housing 20 and the bearing valve housing 40 of the assembly, rotating plates 3, 43 exhibited circumferentially about the interior of each tubular 20, 40 and perpendicular to the tubular annular fluid flow direction, allows fluid to pass from rotational inlet flow ports 4, 47 in rotational plates 3, 43 through reciprocal stationary ports 15, 46 in stationary plates 5,45 to create an avenue and environment of increasing pressure as fluid travels from the proximal end 10 of the vibratory assembly 100, through the upper turbine housing 20, through the bearing valve housing 40, into the lower vent sub 60 and through the distal end 80 of the assembly.

[0049] As the fluid energizes and passes through each rotating plate 3, 43, the rotating plate ports 4, 47 of rotating plates 3, 43 come into communication with stationary plate ports 15, 46 which open and close across each static stationary plate 5, 45, Each rotating plate being affixed to shaft 36 further potentiating shaft_36's rotational movement. This fluid entrance causes a sudden, momentary pressure increase within each respective distal portion 24, 44 of both the upper turbine housing 20 and the bearing valve housing 40 of the vibratory assembly 100. This fluid pressure increase is experienced rearward as well as forward where increased pressure establishes (1) a retrograde pulse that is then directed back up the vibratory tool and along the pipe laying in the lateral well section (with the uncommunication of rotational inlet flow ports 4, 47 and stationary inlet flow ports 15, 46) and (2) anticipates a forward timed jet of fluid pressure created through a turbine-shaft assembly 30 controlled rotational uni-ported system (created via a temporal, rotational communication between rotating aperture 55 and stationary orifice 56), similar to the circumferentially designated plurality of inlet flow ports 15, 47 made to communicate and uncommunicated with inlet flow ports 15, 46 and about the interior of both the upper turbine housing 20 and bearing valve housing 40, where each smaller inlet flow port 4, 15, 47, and 46 creates incrementally larger increases in internalized tubular pressure, rotating aperture 55 and stationary orifice 58 creates one large egressing fluid pulse forward as the rotating ported rotational disc 50 rotates, through rotational locomotion of the turbine-shaft assembly 30, and comes into communication with a stationary orifice 56 in stationary plate 58 that exists perpendicular to the annular tubing that is the lower vent sub 60. In sum, each rotating plate 3, 43 and 50 creates a retrograde and forward pulsation experienced through closure and opening of ports 4 and 15, 47 and 46 and 55 and 56, respectively.

[0050] It should be noted that variations of number, configuration and placement of circumferentially located rotating inlet ports 4, 47 of rotating plates 3, 43 and stationary inlet ports 15, 46 of stationary plates 5, 45, fluid pressure regulation of rotating plates 3, 43 and their temporal communication with corresponding receiving orifices in reciprocating stationary plates 5, 45 and 58, variations of number, configuration and placement of circumferentially located rotating port 55 (or various other ports not shown) in disc 50 (as seen in FIG. 4) and or orifice 56 (or orificesnot shown) (as seen in FIG. 5) in stationary plate 58 can be augmented to either increase or decrease the pressure pulses and vibratory forces the vibratory assembly 100 is capable of producing.

[0051] As well, the configuration of the turbines 32, 34, in terms of turbine blade length, blade pitch, blade circumference and blade thickness, among other physical features, may be modified to (1) increase or decrease pressure or flow within the vibratory assembly 100, increase or decrease vibratory intensity within the vibratory assembly 100 and/or increase or decrease the pressure pulse expressed through the most distal opening (foot valve 64) of the vibratory assembly 100. And, their placeable and replaceable keyed inclusion upon the assembly shaft 36 more readily lends itself to an easily and readily modifiable configuration for different and differing vibration intensities and fluid pressure creation.

Turbines

[0052] The use of a fluid powered turbine is a simple and reliable method for rotation of a drive shaft 36 to operate a valve or other devices. However, a single turbine 32 may require a speed controller to prevent revolutions exceeding the limits of the turbine given a certain flow rate through the turbine. Various methods of speed control exist but can be both complex and expensive such that they reach impracticability (e.g. magnetic speed controllers).

[0053] To alleviate thus issue, the present invention utilizes a reverse pitch on the second turbine 34 in the tandem series. Further, a variable diameter turbine 32, 34 is used in the current embodiment to provide speed control of the upper/primary turbine 32 within each power section (upper turbine 2 and lower turbine 34) of the entire turbine-shaft assembly 30. By changing the pitch, diameter, number of blades and/or thickness of blades (or a combination of all features) the operator can alter the revolutions per second of the turbine-shaft assembly 30. Individually, only one turbine requires pitch and or diameter change within the upper and lower power sections, though, and by changing the dimensions of one of the turbines, for example turbine 34, this will provide the required drag to be placed on the other turbine, or example turbine 32, thereby slowing turbine 32 downeach keyed into the same drive shaft.

[0054] Too, upper power section turbines 32 can be set up with a different pitch and diameter turbines from the lower power section turbines 34 where the rotational direction of each turbine 32,34 are opposite from one another. For example, if turbine 32 is designed for a clockwise rotation, turbine 34 is designed for a counterclockwise rotation and, conversely, if turbine 32 is designed for a counterclockwise rotation, turbine 34 is designed for a clockwise rotation. Therefore, turbine 34 is creating the necessary deleterious function (i.e. drag) retarding the spin of turbine 32 (as shown in FIG. 5). By constructing each turbine 32 and 34 with a different directional flow and a difference in pitch and diameter, an operator can create a power section that can be manipulated to rotate at various and variable revolutions per second.

[0055] In addition, because all the turbines 32 and 34 are individually attached to the drive shaft they can be manufactured (e.g. 3D metal printed) with a combination of pitch and diameter augmentations and modifications as to provide for an array of turbine speeds and provide a vast combination of revolution per second variables with due attention paid to the durable thickness and durability required by all downhole equipment. It is this ability to use modular turbines located in series on a primary drive shaft 36 which makes for a truly versatile, variable speed controller.

[0056] FIG. 2 depicts the outer shell and FIG. 3 the inner functional components of the present invention that is the vibratory assembly system 110 which is run in series (tandem) where the vibratory agitator assembly 100 is connected in the following manner: upper turbine housing 20 to an upper bearing valve housing 29 to a lower turbine housing 39 to a lower bearing valve housing 49 to a lower vent sub 60. FIG. 6 further shows an exploded view of the conjunction of the individual subunits of vibratory agitator assembly 100 as shown connected in FIGS. 2-3.

[0057] In FIGS. 2, 3 and 6 the vibratory assembly system 110 can be seen to run in tandem or series wherein the upper turbine housing 20 can be made to function at a high vibratory intensity (e.g. 40 Hz) and the lower turbine housing 39 can be made to function at a low vibratory intensity (e.g. 10 Hz). Alternatively, the upper turbine housing 20 can be made to function at a low vibratory intensity and the lower turbine housing 39 can be made to operate at a high vibratory intensity. Through this combination of vibratory assemblies 100 into a sequential vibratory assembly system 110, the present invention is capable of simultaneously generated high and low frequency vibration. What's more, the vibratory assembly system 110 can be placed at various location above the drill bit to facilitate rate and depth of penetration.

[0058] Plainly, each turbine housing 20 and 39 is made up of a ported housing that permits control of fluids to each power section 20 and 39. Each of the individual flow ports 4,15 and 47, 46, within either turbine housing 20 and 39 and bearing housing 29 and 49, respectively, can be threaded to allow for isolation of a number of ports educe or increase the rate of flow through the upper, lower or both upper and lower power sections 20 and 39. The ability to control flow into each power section 20 and 39 and bearing valve housing 29 and 49 allows for variable pressure pulse heights to be readily achieved thereby creating a higher or lower water hammer or pulse jet effect. This will also allow for variable pressure drops across the tools that can be readily changed with reconfiguration of the components, of both the vibratory assembly 100, individually, and the sequential vibratory system 110, in combination, by closing off of ports in the event that higher or lower flow rates require rate and adjusting pressure and pulse intensities to achieve desired vibration generation together with maximum pressure pulse effect as the fluid passes through the lower turbines and exits the foot valve 64 in the lower sub (as seen FIG. 4).

[0059] Moreover, just as vibration rate is controlled by fluid speed and pressure as fluid is pumped through the tool at an increasing rate, the higher and faster the fluid pulses travel along the pipe, the greater rotational speed is experienced by the shaft in revolutions and the rapidity with which exiting pulses is experienced), so too is flow further augmented within the vibratory assembly 110 and the sequential vibratory system 110. It is the case that the parameters of the rotating turbines 32, 34 (e.g. fin pitch, outer diameter, circumference, etc..) can positively or negatively affect the frequency of the vibratory forces and the pressure created in the final fluid pressure force. Too, the diameter, shape, placement and number of circumferential ports 4, 15, 47, 46 can have correspondingly inhibitory and/or promotional influences on the creation of pressure within the agitator's annulus.

[0060] In addition to the vibratory forces, pulsing effects cause the pipe to vibrate along its lateral length effecting not only the frictional forces created at the site of the bottom hole assembly but also in a retrograde manner up the drill string. Succinctly, as fluid is pumped down the drill string to the BHA, pressurized fluid contacts and rotates rotational plates 3 and 43, the first rotational ports 4 of the first rotating plate 3 aligning with the first static plate 5 ports 15 wherein fluid is allowed to pass distally, when such ports 4, 15, 47 and 46 are aligned, through to the assembly.sup., turbines 32, 34 which in turn rotates the centrally disposed shaft 36 to propagate fluid flow down the assembly and create vibration, rotate an affixed perpendicularly appended rotational disc 50 and to expel a concentrated, fluid jet through the communication of aperture 55 through stationary orifice 56 of stationary plate 58 that itself is disposed perpendicular to the annular flow of fluid in the lower vent sub 60. Fluid is then expelled fully through the most distal portion (foot valve 64) of the lower vent sub 60 to a forward attached assembly or corresponding downhole device.

[0061] As depicted in FIGS. 1 and 9, a seal 37 and bearing 38 combination of turbine-shaft assembly 30 can be seen to provide occlusion of the centrally deposed pathway running centrally through the rotating plate 43 and stationary plate 45 thereby obstructing flow and redirecting fluid flow into rotating inlet ports 47, through corresponding stationary inlet ports 46 and into the distal chamber of the bearing valve housing 40.

[0062] As well as novel and ergonomic mechanical inventive features, as depicted in FIG. 7, the present invention allows for programming of the assembly to control on and off vibration of the tool via communications port 115. The communications port 115 programs the assembly via a laptop computer. The communications port 115 attaches to the microprocessor 114 through the printed circuit board assembly 113 which accepts the codes from a laptop computer to command the tool to operate with specific.

[0063] FIG. 8 provides for sensor sensing and memory capacity to hold and store relevant commands that, once certain wellbore conditions or command parameters are met, the tool will activate upon brake probe 111 removal (or deactivate trough brake probe 111 introduction).

[0064] The brake probe assembly 120 brake probe 111 is attached to a motor 112 that allows the brake probe 113 to move into the on and off position to activate and de-activate the brake probe 113 through either an inlet port orifice 4, 15, 47 or 46 or through the aperture 56 and orifice 55 of the vibratory assembly 100 or vibratory assembly system 110. The motor 112 is attached to a condition determining sensor 113 or sensors that provide the stored commands to activate the tools brake probe 111. The brake probe assembly 120 can be powered by various means such as a turbine or batteries (not shown). In the attached drawings, the power supply 114 is assumed to be a battery assembly. The power supply 114 provides the necessary power to power sensors 113, activate the motor 112 and initiate the brake probe 111 The power supply 114 also provides power to the onboard sensors 113 that provide the trigger instructions to operate the brake probe 113.

[0065] As depicted in FIG. 8, the brake probe 113 when in the on position position locates into the brake plate 104 thereby preventing the brake plate 104 (fixed permanently to shaft 36) from rotating even as fluid is pumped through the vibratory assembly 100 and/or the assembly system 110. The brake plate 104 is attached to a rotatable plate via the bearing assembly 105 and assembly shaft 36. With the Brake Probe 111 in the on position, the bearing assembly 105 and the shaft 36 (depicted here as a weighted shaft) cannot rotate and does not allow the assembly 100 and/or assembly system 110 to vibrate. However, the flow of fluid to the equipment below the most terminal and distal portion of the assemble 80, such as a mud motor, drill bit or combination of multiple drilling tools known to those in the art (not shown), is unimpaired and unhampered.

[0066] Diagrammatically, the shaft 36 is attached to the lower end of the assembly via the lower bearing section. A shear plate 109 (in the form of a stationary, rotating or combination) is atop the lower bearing section 37 and each has multiple through inlet ports 4, 15, 47, 46 (collectively 111) to allow the flow of fluid. These inlet ports 4, 15, 47, 46 (collectively 111) can be of various shapes and sizes to provide variable measures of fluid to pass. A second rotating shear plate 108 is attached to shaft 36. As the rotating shear plate 108 rotates, the rotating shear plate 108 ports pass over the ports on the lower shear plate 109 to align the ports thereby allowing the flow of fluid through the entire assembly 100 and or assembly system 110 and into the tools below. As the rotating shear plate 108 continues to revolve, the ports move to a closed position preventing fluid from passing through the assembly. The closure of these ports between the rotating shear plate 108 and the non-rotating shear plate 109 create back pressure within the assembly which causes lateral movement along the length of the pipe forward and back. By rotating the shear plate 108 at high revolutions per minute, the number of pressure pulses increases to a point where the assembly 100 or assembly system 110 and wellbore pipe is constantly vibrating. As detailed above, the higher the volume of fluid pumped through the turbine 106 the faster the turbine 106 spins the shaft 36 and the more pressure pulses are created at the shear plates 108 and 109. This provides for a multi-axis, lateral and axial vibration effect to occur thereby reducing pipe to pipe friction contact along the length of the pipe and bottom hole assembly via the agitator vibratory assembly 100 as shown and described.
