赵庄油田沙三段油气成藏潜力分析

通过对东濮凹陷赵庄油田沙三上段构造、储层、油气成藏条件的研究,认为该区沙三上段油藏主要富集于各断块高部位,具有多砂组含油、含油井段长、含油高度大等特点,油藏类型为受构造控制的断块层状油藏。新钻井证实了该区沙三上段油气已聚集成藏,对赵庄构造及整个长垣断层下降盘沙三上段油气勘探起到了积极的推动作用,为下一步滚动勘探指明了方向。

Analysis of potential reservoir of upper ES3 in Zhaozhaung-oilfield

Based on the study of structure,reservoir and hydrocarbon reservoir conditions in the area of Zhaozhuang-Oilfield in Dongpu Depression reservoirs of upper ES3 are mainly enriched in high position of each fault block,With the characteristics of oil exist in many a lot of sandstone,oil in sandstone with a big thickness.The types of reservoirs controlled by structure are Layered and fault block.New wells confirmed that oil and gas have already gathered in the upper ES3 in this area.the study is significant to petroleum exploration of Zhaozhuang-Oilfield and the drop plate of Changyuan-Fault.and points out the next exploration direction.
