摘　　要：鄯善油田属于“低孔、低渗、低粘”油田,经过近十年的注水开发,油田已进入中含水开发期, 接替潜力层逐渐转向Ⅱ、Ⅲ差油层,压裂挖潜对象也转变为Ⅱ、Ⅲ差油层和水淹层,地应力也发生了变 化,人工裂缝方位的不确定性增大。适时引进微地震裂缝监测系统,监测评价裂缝产状,充分利用监测 结果评价研究裂缝规律性,及时进行注水调控,为控制压裂井含水上升、提高改善开发效果起到了积极 作用,为水淹层压裂拓宽了思路。Shanshan oilfield belongs to low porosity, low percolation and low viscidity oilfield. After applied fracture, production potential for single well raises about one times. By water injection development during near decade, the oilfield has already been middle containing water developed period and replacing potential layers turn to Ⅱ、Ⅲ bad oil layer gradually, meanwhile, excavating potential objective for fracture also turns to Ⅱ、Ⅲ bad oil layer and water flooded layer that makes earth stress change and uncertainty of orientation of manmade fracture big. So, microseism and microfrac monitoring system is introduced to monitor and evaluate crack occurrence and using this results fully to study fracture principle, adjust and control water injection in time and exert transmitting flow and increasing production role of cracks which plays a positive way for controlling water containing against raising up and increasing developing effect in fractured wells, opens up a thoughts for fracture to water flooded layer.
