鄂尔多斯盆地胡154富县组油藏建产有利区分析

Analysis Erdos basin reservoir Hu 154 Fuxian formation built favorable area

胡154区块位于鄂尔多斯盆地胡尖山油田中西部,构造上位于伊陕斜坡带。结合近几年采油六厂快速上产的节奏,产建规模逐年加大,对地质储量的需求日益增大,胡尖山油田勘探评价程度相对较高,随着勘探开发的进行及富县组部分生产井投入开发后效果较好。论文通过对胡154区富县组油藏砂体展布、油藏综合评价及其主控因素分析,筛选出富县组I、Ⅱ、Ⅲ类建产有利区,其中I类有利区可以规模建产,落实地质储量345万t,Ⅱ、Ⅲ类有利区需要进一步加大评价研究。为采油六厂2014年上产200万t奠定了坚实的储量基础。

Hu 154 block is located in the midwest Erdos basin Hujianshan oilfield,located in Yishan slope stripe structure. In recent years with the oil six factory fast on the rhythm,production scale of geological reserves increased year by year,the increasing demand,Hujianshan oilfield exploration and evaluation degree is relatively high,with the exploration and development of some production wells and Fuxian group investment in the development of good results.Based on the analysis on the Fuxian Hu district 154 group reservoir sand body distribution,comprehensive evaluation of reservoir and its main controlling factors,screening out the Fuxian group I,class II and III built favorable area,among them I favorable zone can scale to build production,implement the geological reserves of 34.5×104tons,class II and III favorable area need to further increase study on the evaluation of. To lay a solid foundation for the reserves of oil six factory 2014 production 200×104 tons.
