东濮凹陷晚期洼陷成藏系统的油气勘探

根据东濮凹陷油气成藏的期次性,以近洼陷带的断层为界分为主成藏期成藏系统和晚期洼陷成藏系统,主成藏期成藏系统一般位于构造主体,晚期洼陷成藏系统主要分布在近洼陷部位.提出了断层分析法进行洼陷带岩性油气藏成藏条件研究的新思路,把东濮凹陷划分为11个晚期洼陷成藏系统,在濮卫次洼、柳屯次洼、杜寨地区、桥口地区、白庙等地区实施钻探均取得了成功,为东濮凹陷深层洼陷带的勘探发挥了重要作用,取得了明显的社会效益和经济效益.

The Oil and Gas Exploration of Later Period Depression Reservoir Formation System in Dongpu Depression

According to period character of oil and gas reservoir formation, Dongpu Depression is divided to main reservoir-forming period system and later penod reservoir-forming system by bounding fault of near depression , main reservoir-forming period system locates the main body of the structure , later period reservoir-forming system mainly locates the near depression . We put forward the new thinking in subtle oil and gas reservoir-forming condition research in Dongpu Depression with the method of fault-analysising , Dongpu Depression is divided into eleven later period reservoir-forming systems, and we have made great success through drilling wells in Pu-Wei sub-depression, Liutun sub-depression, Qiaokou area , Baimiao area and so on. This new thinking played a important role in oil and gas exploration in deep layer of Dong pu Depression, obtained obviously social and economic benefits.
