苏里格X区块盒8段致密气藏地层水赋存状态及控制因素分析
|
摘要
针对苏里格X区块盒8段致密气藏存在的气水关系复杂、无统一的气水界面、气水分布规律认识不清等问题,应用地质、测井、测试及生产动态等多种资料综合分析该区致密气藏地层水赋存状态及主控因素,将地层水划分为束缚水、毛细管水和可动水3种类型,确认盒8段致密气藏地层水主要受烃源岩生烃强度、储集层非均质性及局部微构造等多种因素控制,其中:烃源岩生烃强度控制区块气水分布的宏观格局,储集层非均质性决定区块局部的气水分布,局部微构造控制同一连通砂体内可动水的垂向运移。该研究为苏里格X区块致密气藏气水分布规律分析提供了可靠依据,并为该区块下步勘探开发选区、选井工作提供了指南。
Focusing on the complex gas-water relation,absence of unified gas-water contact and vague understanding of gas-water distribution in the tight gas reservoirs of He 8 member in X block of Sulige Gas Field,geology,well logging,testing and production dynamics data are applied to comprehensively analyze the formation water occurrence state and main control factors.The formation water is divided into three types:irreducible water,capillary water and movable water.It is confirmed that the formation water in the tight gas reservoir of He 8 member is mainly controlled by the hydrocarbon generating potential of source rock,reservoir heterogeneity and local microtectonics.The hydrocarbon generating potential of source rock controls the macro pattern of gas-water distribution.Reservoir heterogeneity determines the local distribution of gas and water in the block.Local microtectonics controls the vertical migration of movable water in the same connected sand body.The research provides reliable basis for analyzing the gas-water distribution law of X block in Sulige Gas Field and guides the selections of further exploration and development areas and wells in this block.
