摘要
针对注水井分层压力测试过程中存在测试效率低、测试误差大等问题,以桥式偏心分层注水工艺技术为依托进行分层压力测试,优化设计分层压力测试工具,完善分层压力测试方法,解决了原有测试工艺操作难度和测试误差大等问题,实现了多层系油藏注水井分层注水"双卡"单层井下关井分层压力测试,提高了测试效率精度。该技术在长庆油田现场试验了10口井,试验成功率100%,测试成功率100%,应用效果良好。
In view of the layered water injection pressure test in the process of problem such as low test efficiency,great error in the test,in order to bridge eccentric zonal injection technology based on layered pressure test,the optimized design layered pressure test tools,perfect the layered pressure test method,to solve the existing problems such as great error in the test process and test difficult,implements the multi layered water injection reservoir injection Wells'double card'single stratified down-hole shut-in pressure test,and improve the testing efficiency and test accuracy.The technology of 10 Wells in Changqing oilfield pilot test,the test success rate 100%,test the success rate 100%,and the application effect is good.
