Method of proppant oil or gas formation fracture

Abstract

The invention is related to the field of oil and gas industry, particularly, to the methods of oil or gas formation fracture using proppants, i.e. to the technologies of making fracture cracks, and may be used for underground formations processing, particularly for oil formation fractures. In the method of oil formation fracture including high-rate fluid injection into the formation and addition of a proppant into the fluid, polydicyclopentadiene material is used as the proppant. The method enables ensuring a lower friction during the proppant injection into the well retaining the cracks permeability due to the specific density of the proppant close to 1, its high thermal stability and high crushing strength.

1 . The method of oil or gas formation proppant fracture including injecting high-rate fluid into the oil or gas formation;
 adding the proppant to the fluid, characterized in the fact that proppant polydicyclopentadiene material is used.   
     
     
         2 . The method of  claim 1  characterized in the fact that particles of polydicyclopentadiene may be of various shape. 
     
     
         3 . The method of  claim 2  characterized in the fact that particles of polydicyclopentadiene may be elongated and/or polygonal and/or cubical and/or spherical and/or fiber-like. 
     
     
         4 . The method of  claim 1  characterized in the fact that polydicyclopentadiene proppant may be reinforced using additional filler. 
     
     
         5 . The method of  claim 4  characterized in the fact that the additional filler may be ceramic or silicon dioxide or fiber.
