【摘要】 苏里格气田盒8段气藏为河流相低效气藏,储层非均质性强,在开发过程中储层常产水。为此,对气层、水层和气水同产层的测井响应进行了分析比较,根据物性参数分布的差异,确定了不同流体的测井响应模式。盒8段的地层水主要来源于沉积压释水,属于油气伴生水。其形成的主要原因是与低渗透储层中的气水置换不完全、河流相沉积所形成的透镜状砂体以及地层倾向从西倾转为东倾造成的汇水集中有关。更多还原

【Abstract】 The He-8 gas reservoir in the Sulige gas field is characterized by fluvial facies,low efficiency and strong heterogeneity,and producing water during the development.So,the logging responses for gas zone,water zone and water-gas zone are correlated and logging response modes for different fluids are confirmed according to discrepancy of physical property distribution.The formation water of He-8 gas reservoir is mainly from sedimentary compaction water and belongs to oil and gas associated water whose forming reasons are related to incomplete replacement between gas and water in reservoir with low permeability,lens sandbody formed in fluvial facies sedimentary and water catchment caused by dip direction reversed from west to east.更多还原
