摘　　要：针对目前胜利油田筛管完井水平井堵水现状,对水分散乳液聚合物凝胶、相渗调节剂和油溶性树脂选择性水平井堵剂进行了性能评价及矿场应用。其中,水分散乳液聚合物为聚丙烯酰胺,相渗调节剂为阴阳离子表面活性剂,油溶性树脂为改性酚醛类树脂。结果表明,水分散乳液聚合物凝胶可用于非均质油藏点状出水或部分井段出水水平井堵水,油溶性树脂可用于高渗油藏多点出水水平井堵水,相渗调节剂可用于低渗油藏多点出水水平井堵水。In view of the water shutoff in screen pipe completed well in Shengli Oilfield currently, a selec- tire water shutoff agent of aqueous dispersion emulsion polymer gel, relative permeability modifier and oil solu- ble resin for horizontal well was chosen. The performance evaluation on the selective water shutoff agent was conducted, and the selective water shutoff agent was used in the oilfield. Among that the aqueous dispersion e- mulsion polymer was polyacrylamide, the relative permeability modifier was a cationic surfactant and the oil soluble resin was a synthetic resin. The results have shown that the aqueous dispersion emulsion polymer can be used for shutting off the water bursting on a point like spot in heterogeneous reservoir and for horizontal well water plugging in some sections, the oil soluble resin can be used for horizontal well water plugging in the case of multi- point water bursting in high permeability reservoir, and the relative permeability modifier can be used for horizontal well water plugging in the case of multi - point water bursting in low permeability reservoir .
