摘要
针对油田生产井的高含水问题研制了井下油水分离系统,其作用是在井下对油水混合液进行分离,分离后的净水通过增压系统直接回注到同井需要补充能量的油层,油流通过举升系统举升到地面。该系统在辽河油区推广应用后,增加了油产量和采油速度,并具有减少地面污水、保护环境的作用。
In accordance with the problem of high water cut in production well, downhole oil - water separation system has been developed. After separation, clean water will be reinjected into certain reservoirs by booster system, and oil will be lifted to surface. The application of this system in Liaohe oil province shows that, oil production rate has increased, surface contamination has reduced, and environment is protected .
