英台油田特高含水期提高开发水平研究

Study on improving development performance in ultra-high water cut stage of Yingtai Oil Field

英台油田油藏类型为天然水驱构造油藏,目前已进入特高含水开发阶段。针对主力油层动用效果差、分层产状认识困难、稳产难度大等问题,以油藏研究为基础,实施配套技术,通过油田调整和措施挖潜,改善了开发效果:实现了措施降液增油明显、递减率显著减小、含水上升得到控制、最终采收率提高的目标。

The reservoir type of Yingtai Oil Field is natural water flooding structural reservoir. Now it has entered ultra-high water cut stage. Based on reservoir study, the development performance is improved through adjustment and potential tapping combining with matching techniques.
