摘要
本文从研究区志留系岩性垂向分布规律及油气显示出发,认为志留系发育4套储盖组合,分别对应3种储盖组合模式:(1)凹陷内部发育平整型储盖组合;(2)隆起边缘斜坡区发育中-低角度储盖组合;(3)隆起高部位发育高角度储盖组合。在对储层和盖层进行综合评价的基础上,通过有利盖层与有利储层在平面上进行叠合,优选出有利储盖组合分布,结合储盖组合发育模式,明确了有利储盖组合与圈闭类型的对应关系。
Four sets of reservoir-seal associations are hosted in the Silurian strata in the Tarim Basin,Xinjiang.These reservoir-seal associations may be grouped into three types of reservoir-seal association models,including（1） the even reservoir-seal associations developed in the depression;（2） medium-and low-angle reservoir-seal associations developed on the marginal slopes of uplifted zones,and（3） high-angle reservoir-seal associations developed in higher parts of uplifted zones.The favourable reservoir-seal associations are delineated,and their bearings on the trap types are also discussed on the basis of comprehensive evaluation of the reservoir rocks and cap rocks in the study area.
