| 摘 要： | 根据测井、录井资料,对陆西地区所有井的侏罗系西山窑组顶界不整合面上、下的岩性组合做了统计,并从中总结出7种具有代表性的不整合结构,对组成不整合结构的底砾岩、水解带、淋滤带的岩性特征、测井响应、孔渗特征做了系统的分析.通过研究7种不整合结构与油气的运聚关系认为,第Ⅰ种和第Ⅴ种不整合结构最易聚集成藏,第Ⅱ和Ⅲ种不整合结构较易聚集成藏,第Ⅳ种不整合结构也可以聚集成藏,第Ⅵ种和第Ⅶ种不整合结构不易成藏.最后指出,石南油田和石西油田之间未勘探区块是油气聚集的最有利地带.

| Abstract: | according to data of well log,we sumed up the rock trait on the Unconformity and below the Unconformity and found that they could be divided into seven types. We analyzed characteristics of conglomerate at the bottom , weathered zone, eluvia horizon, pore and permeability .It is the easiest way to gather and become reservoirs for type one and five; it is easier to gather and become reservoirs for type two and type three, and it is not easy to gather and become reservoirs for type six and type seven. Finally, it pointed out that the best place which could be the beneficial exploration zone lies between Shixi oil field and Shinan oil field. |
