摘　　要：为了认清长垣南—古龙地区黑帝庙油层油气分布规律,通过地层格架建立与沉积相划分、油源对比等方法,结合构造发育及圈闭特征,采用油气成藏地质条件综合分析方法,研究了油气成藏主控因素及油气藏特征。研究表明:黑帝庙油层发育构造、岩性2种类型油气藏,构造油气藏主要沿长垣南部地区葡萄花、敖包塔及敖包塔南构造带发育,岩性油气藏主要沿古龙地区砂岩上倾尖灭带分布;长垣南地区的油气主要来自供给相对不足的青山口组远源烃源岩,形成远源次生构造油气藏,古龙地区的油气主要来自供给充足的嫩一、二段近源烃源岩,形成近源原生岩性油气藏。In order to make clear of the oil and gas distribution laws of Heidimiao reservoirs in South PlacanticlineGulong area,with the help of the following methods such as the establishment of the stratigraphic hakes,classification of the sedimentary phases,contrasts of the oil sources and so forth,integrating with the structural development and trap characteristics,the main controlling factors and petroleum features are figured out by means of the comprehensive analyzing approach of the geological conditions of the hydrocarbon accumulation.The achievements show that two kinds of the oil and gas reservoir are developed in Heidimiao reservoirs:structural and lithological ones,the former mainly develops along Putaohua,Aobaota and South Aobaota structural belts,the latter generally distributes along the upward pinchout belt in the sandstones of Gulong area;the oil and gas in South Placanticline are principally from the far source rocks in Qingshankou Formation with relatively insufficient supply,and then the farsource secondary structural hydrocarbon reservoirs are accumulated,while the petroleum is mainly from the nearsource rocks in Member Nen Ⅰ & Ⅱ with sufficient supply,thus the near-source primary lithological hydrocarbon reservoirs are enriched.
