Authigenic fiber water shutoff and profile control composition for hydrocarbon reservoir

The invention discloses an authigenic fiber water shutoff and profile control composition for a hydrocarbon reservoir. The authigenic fiber water shutoff and profile control composition is composed of an oil phase, a water phase, a cross-linking agent and an initiator, the oil phase is white oil, and the water phase is carboxymethyl cellulose, polypropylene fiber, polyacrylamide, ethyl acetate, silicon dioxide, diethanolamide, octadecylamine, polyvinyl butyral, polyvinyl ether, silane and water; the cross-linking agent is phenolic resin, and the initiator is ammonium persulfate. The authigenic fiber water shutoff and profile control composition is good in water shutoff and profile control effect and high in stratum adhesion degree, and has water shutoff and ventilation functions. 本发明公开了一种油气层用自生纤维堵水调剖组合物，由油相、水相、交联剂和引发剂组成，所述油相为白油，所述水相为羧甲基纤维素、聚丙烯纤维、聚丙烯酰胺、乙酸乙酯、二氧化硅、二乙醇酰胺、十八烷基胺、聚乙烯醇缩丁醛、聚乙烯醚、硅烷和水，所述交联剂为酚醛树脂，所述引发剂为过硫酸铵。本发明堵水调剖效果好，与地层粘附程度高，具备堵水透气功能。
