摘要
大港滩海油田受地面条件的限制,注水井井型以大斜度井和水平井为主,滩海采用压控开关分注工艺成功实现了井斜大于50°注水井的分注与测调,解决了滩海油田分注技术难题。
The water injection wells in Tanhai Oilfield are mostly High-angle and Horizontal ones due to ground conditions. Separate-layer water injection with pressure control switch is used to resolve the problems in wells whose deviation are larger than 50 degrees.
