摘要
葡北油田是我国第一个采用天然气混相驱开发的油田,注入管柱气密封要求高,起下钻工艺复杂,针对管柱特点和注入压力形成的不返排酸化技术,确保了混相驱开发的顺利实施,并为其它油田注水井的改造提供了新思路。技术应用将会有一定的借鉴和指导意义。
Pubei oilfield is the first one that carried out natural gas miscible flooding, in which the filling tube must be highly sealed and the tripping operation is complex. Aiming at the feature of filling tube and injection pressure, non-flowback acidizing was developed to ensure the implementation of miscible flooding.
