摘要
针对大王庄地区沉积相类型判定结论不一致的问题,以区域构造演化为基础,利用钻井数据、沉积构造标志、测井数据等地质资料,探讨了东营组三段(Ed3)沉积时期周边潜山、洼槽对大王庄地区物源方向、沉积相类型的控制作用,建立了东三段沉积模式.研究结果表明,东三段沉积时期,沉降中心位于研究区东北部,主要接受西南深泽低凸起的物源沉积.东营组沉积期间,随着断陷的抬升,湖盆面积迅速缩小,地形逐渐平坦,沉积相不断延伸,大王庄地区东三段发育曲流河相.沉积相的精细研究为储层预测提供了依据.
To solve the problem of inconsistencies in the determination of sedimentary facies types in Dawangzhuang area,on the basis of regional tectonic evolution,with drilling data,sedimentary structure marks and logging data,this paper discusses the controlling of surrounding buried hills and subsags on the source direction and sedimentary facies types during the sedimentary period of the third member of Dongying Formation(Ed3),and establishes the sedimentary model of Ed3.The results show that the subsidence center is located in the northeast of study area during the sedimentary period of Ed3,which mainly receives the provenance deposits of Shenze low salient in the southwest.During the sedimentation of Dongying Formation,with the uplifting of fault depression,the lake basin shrinks rapidly,the terrain becomes flat gradually,the sedimentary facies continues to extend,and the meandering river facies is developed in the Ed3 of Dawangzhuang area.The detailed study of sedimentary facies provides a basis for reservoir prediction.
