摘　　要：运用温西三区块三间房组不同渗透率的岩心水敏实验,利用激光粒度扫描、扫描电镜以及压汞分析等手段与资料,分析了目标区块储层水敏后微观孔隙的变化特征及其与油田注水开发的关系。深入认识水敏性储层的微观变化有利于预测油层参数变化对注水开发影响,为油田科学开采提供参考。Based on the water-sensitive experiments of the cores of different permeability of J2 s in Wen Xi block 3and the data of laser particle size measuring and SEM and mercury injection,this paper analyzes the change features of the target block reservoir micro pores after water-sensitive and its relationship with the oilfield water flooding development. A deep understanding of the microcosmic changes of reservoir with characteristics of watersensitive is helpful to predict the influence of the reservoir parameter change on the water flooding development,and it provides reference for oilfield scientific exploration.
