饶阳凹陷大王庄地区古近系沙三段层序地层与成藏条件
|
摘要
运用以地层基准面原理为基础的层序地层学理论和分析方法,综合研究钻井、测井和三维地震资料,在饶阳凹陷大王庄地区古近系沙三段至沙二段下亚段中识别出4个层序界面,将其划分为1个三级层序LSC1和3个四级层序MSC1、MSC2和MSC3。在等时地层格架内,系统分析了沙三段烃源岩、储集层、盖层、圈闭条件、运移条件和保存条件及其时空配置关系,并指出在平面上位于Lg1井以西、L494井以南及L110井以北区域为有利勘探区域,有利储集砂体位于MSC2和MSC3旋回发育的辫状河三角洲前缘分流水道砂和席状砂以及MSC3旋回发育的滨浅湖碳酸盐岩滩坝砂。
One long-term stratigraphic base level circle(the 3rd sequence)LSC1 and the corresponding 3 middle- term stratigraphic base level circles(the 4th sequence) MSC1,MSC2 and MSC3 could be distinguished in the third segment of Shahejie Formation and the lower of the second segment of Shahejie Formation within the four se- quence boundaries in Dawangzhuang area,Raoyang sag by using the ways and principles of the high resolution se- quence stratigraphy.Within the correlation framework,it analyzed source rock,reservoir rock,cap rock,tap condi- tion,transport condition and their configuration.On the basis of comprehensive analyses on hydrocarbon accumu- lation conditions in the study area,MSC2 and MSC3 cy- cles are considered to be the most favorable segment of the reservoir rock,and the rock of the braided river delta and the carbonate bar are the targets of the oil exploration. North of the well L110 and the west of the well Lg1 are believed to be the most favorable regions for searching non structure petroleum reservoir.
