Research and application of electric sealing test technology for bridge eccentric separated injection string
摘要
Abstract
The sealing test for bridge eccentric separated injection string normally adopted mechanical sealing test technology which exist the problems of high accident risk, low accuracy in test data and low working efifciency. Research on electric sealing test technology for bridge eccentric separated injection string was conducted to solve the above issues. The packer sealing performance was determined by tube pressure and formation pressure change curves which were real-time monitored by ground control systems and cable. Test results showed that this technology can effectively reduce the risk of downhole accidents such as check sealing apparatus sticking and dropping, sealing segment breakage and fall off in the process of bridge eccentric separated injection string sealing test. And the inspection seal results more intuitive, accurate and efifcient.关键词
