摘　　要：通过对鄂尔多斯盆地南部麻黄山西地区成藏地质条件和成藏过程的系统研究,麻黄山西地区油气藏形成主要受6种因素的控制:①油源是油气成藏的物质基础;②断裂活动控制了构造圈闭的形成,沟通了生油层和储层;③不整合面与断裂相配置,使油气向更广阔的区域运移;④沉积相奠定了成藏的有利区带;⑤异常高压可提高储层的孔、渗能力,作为有利的封盖条件;⑥区域盖层为油气的聚集提供了保存条件。Systematic study of the geological conditions and processes of hydrocarbon accumulations at Mesozoic in Mahuangshan of southern of Ordos Basin shows that there were six main factors controlling hydrocarbon accumulations. （1） Oil source was the material base of oil and gas reservoiring. （2）Fauh activities determined the formation of structural traps and communicated hydrocarbon generations and reservoirs. （3） The unconformity surface allocating with the faults made oil and gas move to the wider regions. （4）Sedimentary facies establish regions of favorable hydrocarbon accumulation. （5） Abnormal high pressures improve reservoir property and reinforce trap conditions. （6） Regional seal control provide conservation for oil and gas accumulation.
