摘　　要：近年来,随着兴古潜山油藏开发的逐步深入,油水界面不断抬升,水平井井段中的锥进底水突破之后,油井含水率上升快,产油量大幅度降低,严重影响了兴古潜山水平井的开发效果。为了兴古潜山油藏水平井长期有效地实现高强度封堵大裂缝、启动小裂缝油藏,筛选出了与稀油油藏条件相匹配的柔性颗粒堵剂和温控凝胶堵剂。室内实验结果表明:2种体系均具有耐高温、稳定性好、抗冲刷能力强的特点,适用于高温裂缝性油藏封堵。Recently,Xinggu block began to produce water,due to a large number of fractures in Xinggu buried-hill reservoir,the bottom water rose rapidly.When the bottom coning water breakthrough the horizontal wells,the production water rose rapidly,the problem of water outlet had seriously affected the development effect of horizontal well in Xinggu buried hill.Starting from the research on water plugging difficulties of horizontal well in buried hill reservoir,the core idea is to plug large fractures effectively and with high intensity for a long time.The temperature controlled gel plugging agent and flexible particle plugging agent were selected to match the conditions of thin oil reservoir.The laboratory test results showed that both of the two systems had high temperature stability and high scouring resistance.They are suitable for plugging high temperature fractured reservoir.
