摘要： The invention relates to the oil-and-gas production industry and can be used for enhancement of the production of oilfield wells as it prevents the fracture from closing by pumping of propping granules (proppant) during the hydraulic fracturing of oil-producing formations. Higher stimulation of a reservoir through using hydraulic fracturing is provided with the proppant as particulate with spherical or elliptic form, made of ceramic, polymer, metal, or glass and having higher roughness than regular proppant, wherein the surface roughness is nonuniform and described by two criteria A and B, varying in the intervals: A =0.0085−0.85; B=0.001−1.0. The proppant manufacturing method comprising the preparation of raw material, mixing, granulation, drying, firing, wherein an additional stage of creation of surface roughness is added at the granulation stage and/or the firing stage.

摘要： A low-density ceramic proppant is formed from a light aggregate of a natural mineral and a ceramic binding material in the form of a proppant granule. The light aggregate expands in volume when burnt so that the density of the aggregate is changed. A method of preparing a proppant material is carried out by pre-crushing and pre-mixing of raw components. This is followed by their granulation into proppant granules, drying and screening of the granules to a selected size. The raw components include at least a ceramic binding material and a light aggregate of a natural mineral that, when burnt, expands in volume so that the specific volume of the aggregate is changed. The burning of the light aggregate may be accomplished before or after the aggregate is mixed with the binding material.

摘要： 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 particulate binding material wherein the particles have an average length-to-width ratio of less than or equal to about 10; thereafter, a formation fracturing process is implemented. Then, the particulate 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 particulate binder 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 micrometers.
