A method of evaluating gel stability of a gel for treating a subterranean formation includes placing a composite core plug into a core holder of a coreflood testing device where the composite core plug comprises first, second, and third core plugs, alternating injection of polymer solution into first and second injection areas, and monitoring a pressure drop across the composite core plug as a function of time. The method further includes identifying a gelation of a gelent solution in the third core plug, where the gelation is indicated by an increase in the pressure drop across the composite core plug, after the increase in the pressure drop indicative of the gelation point, continuing alternating injections of the polymer solution into the first and second injection areas, and identifying a reduction in the pressure drop across the composite core plug indicative of deterioration of the gel.

The present invention belongs to the technical fields of civil engineering, smart material and health monitoring, and provides a viscous damper fluid viscosity monitoring device and method based on piezoceramic transducers, comprising piezoceramic transducers, wires, corks, a baffle and a viscous damper. When the fluid viscosity of the viscous damper changes, the energy dissipation of pressure waves during propagation in a fluid will change, and signals received by the piezoceramic transducers will change, so that the viscosity of the fluid in the viscous damper can be calculated by the amplitude change of the signals received. The device of the present invention has a simple structure and accurate monitoring results, and provides a simple and feasible method for real-time monitoring of fluid viscosity of viscous dampers in engineering.
