摘要

随着油田开发进入中高含水期，长期注水形成的无效循环场将严重影响注水驱油效率。为更好地挖潜剩余油，提高原油采收率,应用数值模拟方法对松辽盆地北二西东块二类油层先导试验区的剩余油和水流优势通道进行模拟，优选出深部液流转向的6注12采井组及萨Ⅱ_13-16主力层系，并设计出高强缓膨颗粒、弱凝胶、强凝胶三段塞式组合开发方式。利用大庆油田北二西区块的地层水进行室内实验优化配方，对增油和降水效果进行预测。结果表明北二西东块二类油层深部液流转向设计方案是可行的。

Abstract

With oilfield production entering into medium-high water-cut stage,the invalid circulation field formed by long-term water injection will seriously affect the efficiency of oil displacement.In order to get the more remaining oil and improve the oil recovery factor,we use the numerical simulation software to simulate the prevailing passageway for the remaining oil and fluid-flow in the pilot area of east Ⅱ oil layer of Beierxi,optimize 6-injection of 12-extraction well group and SⅡ_3-16main layer in the deep fluid diversion,and design triple section plug type combination mode which is composed of high strength retarding swelling particles,weak gelatin and strong gelatin.Depended on laboratory test to optimize the dispensation through using formation water of Beierxi,Daqing,we predict effect of incremental oil and precipitation.The results show that the designed scheme of deep fluid diversion in the East Ⅱ oil layer of Beierxi is feasible.

Key words： Deep fluid diversion; Scheme optimization; Pilot test; SⅡ_3-16; Second reservoir; East Beierxi.
