摘　　要：针对注水油田开发过程中注采井间连通性认识不清、注采结构调整难度大,气顶油田开发过程中气顶气和溶解气渗流关系复杂,常规方法无法认识气顶油田开发特征等问题,为此采用示踪剂监测技术认识油气水流动特征。通过示踪剂监测技术,明确了注水油藏W井组的注采连通关系,根据产出曲线拟合求解得到注采井间高渗通道的物性参数,并调整注采结构,调整后W井组含水率降低,开发效果得到改善。通过示踪剂模拟技术,定量表征了低渗小气顶油藏N的气顶气产出量,明确了开发过程中存在气窜和油侵气顶两个生产阶段。In view of the unclear understanding of the connectivity between injection and production wells,the difficulty of injection-production structure adjustment,the complex seepage relationship between gas cap gas and dissolved gas in the development of gas cap oilfield,and the conventional methods cannot make clear the development characteristics of gas cap oilfield,therefore,the tracer monitoring technology is adopted.Through tracer monitoring technology,the injection-production relationship of W well group in water injection reservoir is clarified.According to the fitting solution of production curve,the physical parameters of high permeability channel between injection and production wells are obtained,and the injection-production structure is adjusted.After adjustment,the water cut of W well group is reduced and the development effect is improved.Through tracer simulation technology,the gas cap gas output of low permeability and small gas cap N reservoir is quantitatively characterized,and it is found that there are two production stages in the development process:gas channeling and oil invasion of gas cap.
