低渗透油藏缝网压裂试验效果研究

摘要

针对低渗透油藏开发过程中暴露出注水压力高且上升速度快,注采井距过大,油水井难以建立有效驱替,油井受效差等矛盾,在A区块进行缝网压裂试验,探索提高低渗透油藏单井产量的有效技术措施,以期为我国低渗透油田开发过程中挖潜增效提供参考.%Crack network experiments are carried out in A block,Daqing Oilfield to solve the issues of developing low permeability reservoir such as the surging pressure of water injected,big spacing between well of injection and production,no effective displacement in oil/water well,and poor effects of wells.Solutions to improve output of single well are offered for development of low permeability reservoirs.
