Abstract
1. Способ обработки подземного пласта, включающий ! обеспечение наличия рабочей жидкости для обработки приствольной зоны, содержащей частицы с нанесенным, по меньшей мере, частичным покрытием из полимера, где полимер осаждают на частицах в результате нанесения, по меньшей мере, частичного покрытия на частицы при использовании раствора полимера, содержащего полимер и растворитель, а после этого воздействия на частицы водной среды таким образом, чтобы растворитель, по существу, выделялся бы из раствора полимера, и таким образом, чтобы полимер, по существу, оставался бы на частицах; ! введение рабочей жидкости для обработки приствольной зоны в часть подземного пласта и ! осаждение, по меньшей мере, части частиц в части подземного пласта. ! 2. Способ по п.1, где рабочая жидкость для обработки приствольной зоны содержит водную жидкость и гелеобразователь. ! 3. Способ по п.11, где полимер включает, по меньшей мере, один представитель из нижеследующих: полиакрилонитрил, сополимер акрилонитрила и метилакрилата, сополимер акрилонитрила и метилметакрилата, сополимер акрилонитрила и винилхлорида, сополимер акрилонитрила и стирола, сополимер акрилонитрила и бутадиена, полиацилат, полиметакрилат, поли(виниловый спирт) или производное поли(винилового спирта). ! 4. Способ по п.1, где растворитель включает полярный апротонный растворитель. ! 5. Способ по п.1, где растворитель включает, по меньшей мере, один представитель из нижеследующих: N,N-диметилформамид; ацетон; тетрагидрофуран; 1,4-диоксан; диметилсульфоксид; тетраметиленсульфон; ацетонитрил; гексаметилфосфорамид; 1,3-метил-3,4,5,6-тетрагидро-2(1Н)пиримидинон; пропиленкарбонат или э�1. A method of processing an underground formation, including! providing a working fluid for treating a near-barrel zone containing particles coated with at least a partial polymer coating, where the polymer is deposited on the particles by applying at least a partial coating to the particles using a polymer solution containing a polymer and a solvent, and after this exposure to the particles of the aqueous medium in such a way that the solvent essentially separates from the polymer solution, and so that the polymer essentially remains on the particles; ! the introduction of the working fluid for processing the near-stem zone in part of the underground reservoir and! sedimentation of at least a portion of the particles in a portion of the subterranean formation. ! 2. The method according to claim 1, where the working fluid for processing the near-barrel zone contains an aqueous liquid and a gelling agent. ! 3. The method according to claim 11, where the polymer includes at least one representative of the following: polyacrylonitrile, a copolymer of acrylonitrile and methyl acrylate, a copolymer of acrylonitrile and methyl methacrylate, a copolymer of acrylonitrile and vinyl chloride, a copolymer of acrylonitrile and styrene, a copolymer of acrylonitrile, acrylonitrile, polymethacrylate, poly (vinyl alcohol) or a derivative of poly (vinyl alcohol). ! 4. The method according to claim 1, where the solvent comprises a polar aprotic solvent. ! 5. The method according to claim 1, where the solvent includes at least one representative of the following: N, N-dimethylformamide; acetone; tetrahydrofuran; 1,4-dioxane; dimethyl sulfoxide; tetramethylene sulfone; acetonitrile; hexamethylphosphoramide; 1,3-methyl-3,4,5,6-tetrahydro-2 (1H) pyrimidinone; propylene carbonate or
