江汉油田分层注水技术现状及改进方向

On Status of Separated Layer Waterflooding Technology in Jianghan Oilfield and Its Improvement

随着江汉油区进入中后期开发阶段,分层注水技术得到了广泛应用。常规偏心分层注水是目前应用最为普遍的注水技术,分层注水新工艺如桥式偏心分注、同心集成分注、恒流分注以及智能分注等也在江汉油田得到了应用。分层注水测调技术及配水器的改进应围绕解决投捞调配效率低、工作强度大、测调效果差、层段合格率低等问题进行。

Separated layer waterflooding technology is widely used in jianghan Oilfield which is in the mid--to--late period of development. Its new processes such as bridge bias process, concentric integrated process, constant current process and smart process are also used in Jianghan Oilfielck The improvement of Separated layer waterflooding test modification technology and water distributor should evolve around solutions to the problems of low--efficiency trip- ping distribution, heavy workload, poor effect in test modification and low percentage of qualified intervals.
