曲堤油田馆陶组油藏能量状况分析及开发方式优化研究

曲堤油田馆陶组属于具有一定天然能量的稠油断块油藏.初期主要利用天然能量开发,根据目前油藏不同部位压力、产量、含水等油藏动态参数变化及天然水侵状况的分析,对油藏能量状况进行了深入研究,进一步对油藏不同开发方式下的开发效果进行了对比,优化出适应于本油藏的特殊注水方式--腰部注水,为该油藏最终取得较好的开发效果打下了基础.

Research of Energy Analysis and Development Fashion Optimization in Guantao Formation Reservoir of Qudi Oilfield

In Qudi oilfield,Guantao formation is a fault-block heavy oil reservoir with certain natural energy on which the production mainly depends in initial stage.But latter,dynamic parameters such as pressure,yield,water-cut have changed and water-out has occurred.Through our research on energy status of various part of this reservoir and development effects under different scheme,a special waterflood project-flood at mid-part of structure is posted.This has laid a good foundation for the further production.
