摘　　要：针对长岩芯试验研究注采速度敏感性中存在的可重复性差、围压与系统压力高、误差较大、注入速度与实际地层气水界面运动速度偏大等问题,提出了采用短岩芯进行物理实验的研究方案与技术思路,完成了注气速度敏感性实验和采气速度敏感性实验,取得了油藏改建成储气库时有关注气速度与库容能力、采气速度与水驱气效率的一般性认识。对我国的能源战略规划、西气东输工程等具有重大意义。Because the poor repetition, high confining pressure and system pressure, fairly high error, high injection rate and actual moving speed of gas and water contacting face in the formation lie in the long core experiment on injection-production rate sensibility, short core is used in the physical experiment and the experiments on the sensibility of gas injection rate and production rate finished, the general concept about the gas injection rate and storage capaticy, gas production rate and efficiency of gas by waterflood is obtained which have great meanings to layout energy and gas transportation from west to east in our country.
