摘要
在储层精细地质描述的基础上,采用剩余油综合描述技术,分析了杏北二次加密后低渗透薄差储层剩余油潜力分布状况,通过优化三次加密井网部署、完井方式,充分挖掘薄差储层剩余油潜力,采取的主要做法是在井网部署上加密井与原井网相结合,与注采系统调整相结合,与后期三次采油相结合;在完井方式上,针对不同的潜力分布特点,分别采取多段限流法压裂、薄隔层限流法压裂、大跨距限流法压裂,以及高密度、大孔径、深穿透加复合酸处理等完井工艺。取得了较好的三次加密调整效果,形成了配套的三次加密调整技术。
Based on detailed geologic characterization of reservoir, this paper uses integrated remaining oil description technique to analyze remaining oil distribution potential of Xingbei area after secondary infilling. It optimizes tertiary infilling deployment and completion pattern to tap remaining oil potential of thin and poor layers. The main implementation of well pattern deployment is to combine infilled wells and original patterns, combine with injection-production system adjustment, and combine with tertiary production in later stage. Completion is to use multi-segment current limit fracturing, thin barrier current limit fracturing, large span current limit fracturing, and high density, large pore diameter, deep penetration with compound acid processing.
