The polymer proppant and method for producing the same relate to oil and gas production technology using materials of high-molecular weight compounds with higher requirements for physical and mechanical properties. The proppant is used as propping granules utilized in the oil and gas production by a method of hydraulic fracturing of formation. The technical result achieved by implementation of the present invention is an increase in thermal strength of the proppant whose material provides a compressive strength of at least 150 MPa at a temperature of not less than 100° C. The polymer proppant represents microspheres of metathesis-radically cross-linked mixture of oligocyclopentadienes.

There is provided a resin formulation comprising a resin precursor, a crosslinking additive, a photoinitiator, and at least one luminescent dye, wherein the crosslinking additive comprises a functional group selected from the group consisting of hydroxyl, alkoxyl, carboxylic acid, amine, amide, alkylacrylate, acrylate, epoxy, alkyl and heterocycloalkyl. The crosslinking additive of the resin formulation may help to homogeneously disperse the luminescent dye in the resin formulation and decrease the viscosity by improving the miscibility and polarity between the resin precursor and the luminescent dye, leading to an increase of solidification rate of the resin formulation during 3D printing such as stereolithography and digital light processing (DLP). There is also provided a method of preparing the resin formulation and uses of the resin formulation thereof.
