摘要
Abstract
This paper studies the geochemical characteristics of the Permian Pingdiquan Formation hydrocarbon source rocks in the Dongdaohaizi sag of Junggar Basin in China through analysing the characteristics of the organic matter abundance,type,maturity and thickness of the hydrocarbon source rocks. There develops and widely distributes over lacustrine mudstone in Pingdiquan Formation.These mudstone constitutes the principal hydrocarbon rocks in the Dongdaohaizi sag. According to this study,the hydrocarbon rocks have huge thickness and are distributed widely and their total organic carbon content (TOC)is abundant but the organic matter type is of poor quality. The organic matter is of mature degree at present.An integrated evaluation of the Pingdiquan Formation hydrocarbon source rocks in the Dinan area shows as below,the source rocks are of medium to superior quality,the organic matter type is mainly Ⅱ2-Ⅲ,and the thermal evolution degree is up to mature or the oil-generating peak phase.The threshold depth is 2 530 m and the oil-generating peak depth is 2 900 m or up and down.Coupled with the analysis of the data about the adjacent regions,the paper thinks that the Pingdiquan Formation hydrocarbon source rocks in the sag have high TOC,superior organic matter type,and high mature or oil-generating peak thermal evolution degree.They have favourable resources potential.关键词
