【摘要】 为了能早日在六盘山盆地获得工业性油流,基于野外露头、最新地震、钻井资料以及前人认识,系统分析了六盘山盆地油气成藏生储盖组合、平面展布及其成藏时空匹配关系。研究表明:古近系寺口子组砂岩能作为区域性储层,含石膏层清水营组泥岩可作为区域性盖层,乃家河—马东山组低成熟度烃源岩是油气成藏的主要地质因素;油气成藏时空匹配具有良好对应关系,在埋深较大的构造圈闭区域有可能发现油气藏,罗川1、黑城和九彩1是重点研究区域。更多还原

【Abstract】 In order to obtain industrial oil flow in Liupanshan Basin as soon as possible,generation- reservoir- caprock,horizontal distribution as well as time- spatial relations of reservoir forming of Liupanshan Basin is systematically analyzed based on the data and previous understanding of field outcrop,latest seismic survey and drilling operation. The research indicates that sandstone of Sikouzi Formation in Paleogene period can serve as regional reservoir; gypseous mudstone of Qingshuying Formation can serve as regional caprock; low mature source rock of Niejiahe – Madongshan Formation is the major geological factor for the hydrocarbon accumulation; however,the time- spatial match of hydrocarbon accumulation has good corresponding relations; oil/gas reservoirs can be discovered in structural traps with large buried depth. Luochuan 1,Heicheng and Jiucai 1 are the major areas for research.更多还原
