摘　　要：针对黄骅坳陷孔南地区孔店期湖盆类型为陆相断陷盆地这一特点,采用陆相层序地层学的理论及其技术方法,充分利用岩心、测井和地震资料,确定层序界面及体系域界面,将研究区孔店组划分为1个二级层序、4个三级层序和12个体系域。通过构造层序地层分析,建立了古近系孔店组的等时构造-层序地层格架,实现了孔南地区的层序地层对比。最后分析了孔南地区孔店组的生储盖组合模式以及油气分布规律,为孔南地区油气勘探开发提供了一套新的研究思路。The lake basin Kongdian Period in Kongnan area,Huanghua Depression is continental rift-faulted basin,aiming at this characteristic, taking continental sequence stratigraphy theory and technology as guide,on the basis of sufficiently using core,well logging and seismic data,sequence boundary and system tract boundary are identified. One second-order sequence,four third-order sequences and twelve system tracts were distinguished in Kongdian Formation. Afterwards,through analysis of tectonic-sequence stratigrahy, isochronal tectonic-sequence strata framework of Kongdian Formation, Eogene system was built to realize the sequence strata comparison of Kongnan area.Finally,the combination pattern of source rock,reservoir and cap rock were analyzed,and favorable oil & gas bearing belts were predicted.This provides a new series of study clue for hydrocarbon exploration and development in Kongnan area.
