Frequently pulling out and putting down string result of high strength work for worker. Several killing well makes second testing formation pollution from killing fluid,which affect testing effect and lower testing data accurate. Aiming at above problems, Integration combination technology of perforation and testing and fracture and hydraulic jet pump fast flowing is developed based on formerly perforation and testing combination,fracture and hydraulic jet pump fast flowing production combination construction. This technology had been successfully carried out on Huo20 well. Locale applying shows that the technology is operated easily,safely and has short construction period. It is also integrity high efficient new technology that protects formation gets production deliverability accurately and meets production needs.%在对储层进行压裂改造中,由于频繁起下管柱,使试油周期延长,对测试层造成二次污染,降低了测试资料准确性,影响了试油效果.针对以上问题,开发了射孔、测试、压裂与水力泵快速返排求产一体化联作工艺,并在霍20井进行了成功实施.现场应用表明:该工艺操作方便,安全可靠,施工周期短,是一套完整高效有利于保护油气层、准确获取地层真实产能的新工艺、新技术,满足了生产要求.
