RESERVOIR CHARACTERIZATION METHODS FOR FLUVIAL RESERVOIR AND THEIR IMPACT ON OIL FIELD DEVELOPMENT: A CASE FROM RESERVOIR A OF BZ OIL FIELD, BOHAI BAY BASIN
-
摘要:
河道砂体是渤海湾海域主力储层类型，储层分布和连通性的刻画对油藏管理和挖潜有重要的指导作用。从渤海BZ油田动态资料入手，发现主力储层A的先前地质认识无法解释生产井的动态差异，通过进一步开展精细等时地层对比，识别出储层A发育三期叠置河道，具有两套油水系统；采用等时地层切片方法，进一步证实储层A具有非均质性，发育两种典型的河道砂体叠置关系：“孤立型”和“桥接型”。综合应用精细地层对比、地层切片技术和动态资料，能够获取储层展布和连通性、油水分布规律的新认识，为河流相储层开发提供可靠的地质依据，有效地指导油藏生产和井网方案的调整。
Abstract:Channel sand is the key contributor to oil production in Bohai Bay Basin, and reasonable understanding of distribution and connectivity of the channel sand is crucial to reservoir management and potential tapping. This paper started with the difference of production performance in BZ oil field, and previous geological understanding of reservoir A could not account for its dynamic behaviors. Detailed isochronal well correlation was then conducted to identify vertical heterogeneity caused by three-stage channels and two oil-water systems. Stratal slices were incorporated to confirm plane heterogeneity and recognize two typical stack patterns of channel sand, i e. stand-alone and bridge-linked channels. Integration of detailed isochronal well correlation, stratal slice and production data can provide reliable information for geological understanding of fluvial-reservoir development. New understanding of reservoir connectivity, distribution and oil-water distribution is efficient to guide the adjustment of development plan and well pattern.
