摘要:
青东凹陷沙四上亚段烃源岩成烃物质基础、生排烃特征、有效源岩分布及资源潜力评价系统研究表明,青东凹陷沙四上亚段烃源岩成烃物质基础良好,具有与东营凹陷沙四上亚段烃源岩相似的特征,均发育咸化还原环境下优质烃源岩,是青东凹陷最重要的一套烃源岩。烃源岩生烃门限为2250m左右,排烃门限为2500m左右,具有“早生速排”的特点,排烃效率较高。沙四上亚段有效烃源岩主要分布于青东凹陷北部、中部洼陷以及南部洼陷的少部分区域。估算青东凹陷沙四上亚段烃源岩总资源量丰富,目前研究区勘探程度较低,勘探潜力较大。
Abstract:
This paper studied the hydrocarbon material base,the generation and expulsion of hydrocarbon,the distribution of effective hydrocarbon source rocks and the evaluation of resource potential for hydrocarbon source rocks of upper Es4 in Qingdong Sag.It was indicated that the hydrocarbon material base of hydrocarbon source rock of upper Es4 in Qingdong Sag was favorable,and had similar characters with the hydrocarbon source rock of upper Es4 in Dongying Sag.And the high quality hydrocarbon source rocks developed in salt and reducing environment were the foremost hydrocarbon source rocks in Qingdong Sag.The oil generation threshold of hydrocarbon source rocks was about 2,250 m,and the oil expulsion threshold was about 2,500 m.So it was characteristics of“early generation and fast expulsion”,with high efficiency of hydrocarbon expulsion.The effective hydrocarbon source rocks of upper Es4 were mainly distributed in the north and middle low-lying as well as small part of south low-lying in Qingdong Sag.It is calculated that the total resource quantity of Upper Es4 hydrocarbon source rocks in Dongying Sag was abundant.At present,the exploring extent of the research area is lower,and the exploring potential is greater.
