【摘要】 黄骅坳陷孔南地区的主干断裂(沧东断裂和徐黑断裂)对孔店期沉积盆地的形成和演化具有控制作用,孔店期残留盆地的总体面貌与原型盆地有巨大差异,残留盆地明显缩小。孔南地区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。文中结合钻井、地震、测井等资料,并对应孔店期岩相古地理背景,确定了孔三段残留盆地的边界,应用碎屑重矿物稳定系数和泛克里金法(universal Kriging)对孔南地区孔店期古湖盆进行原型盆地边界恢复。更多还原

【Abstract】 The main fractures in Kongnan Area of Huanghua Depression such as Cangdong Fracture and Xuhei Fracture have a controlling role for the formation and evolution of depositional basin.The residual basin at Kongdian stage is different from the original basin and is clearly diminished.The lake basin in southern Kongdian Area is the catagenesis basin reformed by tectonic movement at late stage and its edge is formed by tectonic rising and denudation.Combined with the data of well,seismic and logging,and corresponding the lithofacies palaeogeograph at Kongdian stage,this paper confirmed the boundary of residual basin of the third member of Kongdian Formation.Using the stability coefficient of heavy mineral and universal Kriging method,the boundary of original basin in southern Kongdian Area was recovered.更多还原
