    摘要: A polymer material for proppant in the form of a metathesis-radically cross-linked mixture of oligocyclopentadienes and methylcarboxy norbornene esters is obtained by mixing dicyclopentadiene with methacrylic esters and polymer stabilizers, heating the mixture to a temperature of 150-220° C., holding at said temperature for 15-360 minutes, and then cooling down to 20-50° C. A radical initiator and a catalyst are added successively to the resultant mixture of oligocyclopentadienes and methylcarboxy norbornene esters. The polymer matrix is heated to a temperature of 50-340° C., is held at this temperature for 1-360 minutes and then is cooled to room temperature. A technical result achieved by implementation of the present invention is an increase in thermal strength of the proppant material, providing a compressive strength of at least 150 MPa at a temperature of not less than 100° C.

    摘要: The material for proppant and method for producing the same relate to the chemistry of high-molecular weight compounds, and more particularly, to polymer materials with high requirements for physical and mechanical properties, for instance, for the production of proppants, i.e., propping granules, used 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 material providing for a compressive strength of at least 150 MPa at a temperature of not less than 100° C. The method consists in the following. A mixture of oligocyclopentadienes is obtained by heating dicyclopentadiene (DCPD) to a temperature of 150-220° C. and holding at this temperature for 15-360 minutes. The oligomerization of dicyclopentadiene occurs. The mixture of oligomers is cooled down to 20-50° C., and polymer stabilizers, radical initiators, methacrylates and a catalyst are sequentially added thereto. The resultant polymer matrix is heated up to a temperature of 50-340° C. and is held at this temperature for 1-360 minutes, and thereafter is cooled down to room temperature. A metathesis polymerization (MP) and radical polymerization (RP) cross-linkage of the mixture of oligocyclopentadienes with methacrylic esters occurs.

    摘要: The increased thermal strength polymer proppant and method for producing the same relate to the oil and gas production technology using materials of high-molecular compounds, especially to proppants of polymer materials with high requirements for the physical and mechanical characteristics, utilized as propping granules in the oil and gas production by a method of hydraulic fracturing. The proppant is made of a metathesis-radically cross-linked mixture of oligocyclopentadienes and methylcarboxy norbornene esters. The proppant represents microspheres having a roundness and sphericity of at least 0.9 for no less than 80% by weight, whose average size being in the range 0.25-1.1 mm and a bulk density being in the range of 0.5-0.7 g/cm3. The technical result is an increase in thermal strength of the proppant material, providing for a compressive strength of at least 150 MPa at a temperature of not less than 100° C.
