摘　　要：基于黄骅坳陷孔南地区大量的钻孔资料和地震资料,通过对孔店组地层厚度的初步复原,识别出了孔店期4个阶段盆地内的凸起与凹陷等构造单元的空间展布特征,恢复了各个阶段陆相断陷盆地的古构造单元,并初步获得了孔店期盆地的演化过程:盆地南北部的古构造单元具有明显的差异性,整体上盆地北部构造单元更为多样、演化过程更为复杂,由单断式盆地向双断式、两凹夹一凸型盆地演化;盆地南部则较为简单,盆地由坳陷型向单断式、再向双断式发展。Based on the borehole data, seismic data and the preliminary restoration of the strata thickness of Kongdian Formation, the authors identified the space distribution characteristics of the raised and depressed tectonic units in Kongdian period during its four basin stages, restored the ancient tectonic units in the various stages of the continental faulted basin, obtained the evolutionary process of the basins in Kongdian period ： the ancient tectonic units, in the south and north of basin, were of obvious differences, on the whole, the geotectonic elements were more various and the evolutionary process was more complex in the north basin, and the mono-faulted ba- sin evolved into ＂double-faulted＂ basin and ＂double layer structure＂ basin; it was less complicated in south basin, and compression depression basin developed into the mono-faulted first, and then into ＂double-faulted＂ basin.
