摘要
随着海外河油田进入“双高”注水开发期,油田产量也进入递减阶段,常规的周期注水、温和注水和分层注水、水井调剖等工艺措施,无法解决油层深层调整和改善平面矛盾等问题。采用大剂量的深度调剖,虽在一些油田取得一定效果,但只能一次性改善纵向剖面,且有效期缩短、成本高。针对这些情况,在海1块开展了“LPS”深部调驱技术的研究与现场试验,并取得较好的稳油控水效果。
Haiwaihe oilfield has entered high water cut, high recovery percent and production decline stage. Conventional processes, such as cyclic, moderate and stratified water injection, and water well profile control, can not solve problems in reservoir. Deep profile control has been effective in some reservoirs, but only improved vertical profile temporarily, and is high cost. Therefore, a study and field test of 'LPS' deep profile control for oil displacement has been conducted in block Hai 1, and it has stabilized oil production and controlled water cut.
