Abstract
This invention relates to the oil and gas industry, in particular, to methods affecting the formation productivity at the oil and gas production stage.
A method for fracture propping in a subsurface layer, which ensures a reliable protection of wells from the proppant carryover from the fracture, has been proposed.
According to the proposed method, a fracturing fluid is mixed with a propping agent and granulated binding material with a length-to-width ratio of less than or equal to 10;
thereafter, a formation fracturing process is implemented. Then, the granulated binding material hardens and forms a homogenous firm mass with the propping agent, which impedes the closing of the fracture and precludes proppant carryover from the fracture.
Or, a fracturing fluid composition obtained by mixing a propping agent with a binding compound in the form of a powder whose size varies from about 1 to about 500 µm. A
gravel-packed filter is then constructed; the said filter is based on the application of the working fluid comprising a propping filler and granulated binding component with a length-to-width ratio of less than or equal to 10, or comprising a propping filler and a binding compound in the form of a powder with a size varying from about 1 to about 500 M~~pOMeTpOB.
