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.
