摘要

华北南部地区上古生界烃源岩主要包括煤系暗色泥岩、煤岩和炭质泥岩，从原始沉积特征来看,南华北盆地石炭系—二叠系烃源岩比北部渤海湾盆地沉积厚度更大。华北南部地区上古生界大致经历了3次埋藏生烃过程：印支早期生烃、燕山中期生烃、喜马拉雅晚期生烃，部分地区如开封坳陷、洛阳—伊川地区、合肥盆地、丘县—冠县凹陷、黄口凹陷、谭庄—沈丘凹陷，在燕山运动期已经达到最高演化程度和最大生烃期，在喜马拉雅期基本不具有生烃潜力。渤海湾盆地中的惠民凹陷、东濮凹陷、东营凹陷、沾化凹陷的晚期生烃潜力较大；车镇凹陷、莘县凹陷北部、鹿邑凹陷、倪丘集凹陷等晚期生烃潜力一般。

Abstract

The upper Paleozoic source rocks include dark mudstone in coal measures,coal,and carbonaceous mudstone in the southern north China.In the primary sedimentary settings,the thickness of Carboniferous and Permian source rocks in the southern north China is larger than that in the north Bohai Bay basin.The upper Paleozoic source rock went through three times of hydrocarbon generation: early Indosinian,Yanshanian,and late Himalayan.In some places (i.e Kaifeng sag,Luoyang\|Yichuan,Hefei basin,Qiuxian-Guanxian sag,Huangkou sag,Tangzhuang\|Shenqiu sag),the hydrocarbon source rock reached the highest thermal maturity and the maximum hydrocarbon generation at the Yanshan Period and ceased the hydrocarbon generation at the Himalayan Period.In the Bohai Bay basin,the late hydrocarbon generation potential of source rocks in the areas of HuiMing,DongPu,DongYing,ZhanHua is large,but general in the areas of Chezheng,north Xinxian sag,Luyi,and Niqiuji.

Key words： Upper Palaeozoic; Source rock; Hydrocarbon generation potential; Southern north China.
