Research on formation stages of hydrocarbon reservoirs in Qiaokou area of Dongpu sag;
东濮凹陷桥口地区油气藏形成期次研究
Qiaokou area is located at the south of central uplift belt of Dongpu depression,where there is significant exploration potential with good structural condition and abundant hydrocarbon resource and low identified degree(only 18 28% ), particularly in Es 3 section(below 10%).
桥口地区位于东濮凹陷中央隆起带南部 ,构造条件好 ,油气资源丰富 ,目前探明程度很低 ,仅 1 8 2 5 % ,沙三段更低 ,不到 1 0 % ,因此具有很大的勘探潜力。
