摘要
非构造圈闭已成为目前世界油气勘探的重点和热点,不同的地质环境形成的非构造圈闭各异。川西地区由于特殊的成藏环境,形成的非构造圈闭类型多,机理复杂,对该区陆相非构造圈闭类型进行系统划分并进行合理的评价,对于勘探部署具有重要的指导作用。文中按形态(主)—成因(辅)综合分类原则,把川西地区非构造圈闭分为三大类,六亚类,根据实际成藏特征优选出了相应的评价方法技术,研制出了较为合理的评价模板,同时也可作为其他领域圈闭评价的参考。
So far,non-structural traps have become important and difficult exploration targets in world oil and gas industry.Different geological settings form different non-structural traps.There are many types of non-structural traps with complex mechanism due to specific reservoir-forming settings in west Sichuan.This paper has a systematic classification and a reasonable evaluation of the continental facies non-structural traps,which may guide an exploration strategy in west Sichuan.Non-structural traps can be classified into 3 types and 6 subtypes according to the forms(primary)and the genesis(secondary).In addition,an optimal and corresponding appraisal method is chosen based on actual reservoir-forming characteristics,and a relatively reasonable appraisal model is studied which may be a reference for trap evaluation of other types and other domains in west Sichuan.
