【摘要】 黄骅坳陷南部的孔店组是渤海湾裂陷盆地古近纪最早的沉积地层。孔店组分布在相向倾斜的沧东断层与徐西断层构成的地堑之中。孔店期湖盆为受后期构造运动改造的"后生盆地",其边缘为构造抬升引起剥蚀形成的边缘。对这种残留湖盆边界的确定方法为测井与地震资料相结合,以测井资料为基础,地震资料为补充确定湖盆边界,进而进行区域的原型盆地恢复。更多还原

【Abstract】 The Paleogene Kongdian Formation in the southern Huanghua Depression is the earliest deposited strata in the Bohai Bay rifted basin.The Kongdian Formation was distributed in the inclining graben constituted by the Cangdong fault and Xuxi fault.The lake of Kongdian Formation is affected by later tectonic movements modified and named"epigenetic Basin",the edge of the srosion caused by tectonic uplift to form the dege.The boundary of this method for determining the residual basin was the combination of logging and seismic data,based on well log data,and added seismic data to determine the lake to supplement the border,then prototype the basin in the region.更多还原
