摘　　要：根据地震资料、钻井资料,对黄骅坳陷孔南地区孔店组残留地层进行精细研究,获得对孔店组地层的沉积特征深刻认识,进而分析孔店期徐西断层拉张作用和走滑作用对孔店组沉积的控制作用,并得出徐西断层在孔店期的构造活动规律:孔店期徐西断层的拉张作用和走滑作用同时进行,并且拉张作用和走滑作用均持续增强。According to seismic,drilling data,study of residual formation of Kongdian Formation in Kongnan area,Huanghua Depression,the profound understanding for the sedimentary features of Kongdian Formation was gained.And then the authors analyzed the control action of extension and strike-slip motions of Xuxi fault during Kongdian stage to the Kongdian formation deposition and drawed the tectonic active law of Xuxi fault in Kongdian stage：there was not any active of Xuxi fault during No.3 section of Kongdian Formation and No.2 section of Kongdian Formation deposition stages,the extension and strike-slip of Xuxi fault happened at the same time in No.1 section of Kongdian stage,and the extension and strike-slip continued to turn strong.
