摘要/Abstract

摘要： 苏里格气田南区下奥陶统马家沟组马五5亚段发育海相碳酸盐岩储集层，气藏无明显气水界面，但开发过程中气井均存在不同程度产水。通过地层水化学特征分析、测井曲线重叠法和交会图法，明确了地层水体类型、分布模式。结果表明，马五5亚段地层水属于封存较好的古代残余海水，存在底部滞留水、气水同层和透镜状水体3种分布模式，其中水层和气水层的深侧向电阻率界限为266 Ω·m，气水层和气层的深侧向电阻率界限为710 Ω·m

Abstract: Marine carbonate reservoirs are developed in Ma-55 submember of the Lower Ordovician Majiagou formation in the southern district of Sulige gas field, which have no obvious gas-water interface. But gas wells produce water during the development process. Based on indepth analysis of chemical characteristics of formation water, logging curve overlapping and cross-plot methods, the paper determines the formation water type and distribution pattern. The results show that the formation water in Ma-55 submember belongs to well-sealed ancient residual seawater and 3 distribution patterns exist in the submember including retained water at the bottom, gas and water in the same layer and lenticular water, among which the boundary of deep lateral resistivity between aquifer and gas-water zone is 266 Ω·m and that between gas-water zone and gas zone is 710 Ω·m
