摘　　要：牛心坨油田为低孔低渗高凝稠油油藏,原油黏度高,含蜡量高,油水流度比的差异较大。已进入中高含水期(70%以上)产量快速递减阶段,以往所进行的措施(压裂、调剖、分注)无法起到稳油控水作用,目前已展开聚合物/活性剂二元复合驱的现场驱油应用。在辽河油田的地层温度范围内,B型表面活性剂在与不同浓度聚合物溶液复配时,体系的表面张力达到10-3数量级,达到牛心陀油田复合驱油体系的要求。Niuxintuo low porosity and low permeability oilfield coagulation oil reservoir, high oil viscosity, high wax content, the oil flow ratio greater difference. A period of high water content （70%） yield rapid decline phase has entered, in previous measures （fracture, profile, separate injection） can not play a role in stabilizing oil controlling water, has commenced polymer / active agent binary compound drive oil field applications. Liaohe oil field in the formation temperature range, B—type surface active agent in the polymer solution with different concentrations of compound when the surface tension of magnitude to 10—3, to beef heart Tuo oil flooding system requirements.
