摘要
烃源岩生烃特征的认识,是明确含油气盆地资源潜力、分析油气成藏过程的基础。东营凹陷孔店组烃源岩埋深大、演化程度高,对其生烃特征认识相对有限。通过选择研究区不同位置的、钻至烃源岩层的井,并根据钻录井资料,建立地质格架,合理设置地质参数,对研究区孔店组烃源岩热演化史和生烃史进行了模拟。结果表明,孔店组烃源岩进入生烃门限早,大规模生烃时间早,生烃高峰持续时间久,对于深部地层早期成藏具有积极意义。
Understanding the hydrocarbon-generating characteristics of source rocks is the basis for clarifying the resource potential of hydrocarbon-bearing basins and analyzing the hydrocarbon accumulation process. The Kongdian Formation source rocks in the Dongying Sag are deeply buried and have a high degree of maturity, so the understanding of their hydrocarbon-generating characteristics is relatively limited. The thermal evolution history and hydrocarbon generation history of the Kongdian Formation source rocks in the study area were simulated by selecting wells drilled to the source rock layers at different positions in the study area, establishing a geological framework based on the drilling and logging data, and setting reasonable geological parameters. The simulation results show that the Kongdian Formation source rocks enter the hydrocarbon generation threshold early, the large-scale hydrocarbon generation time is early, and the hydrocarbon generation peak lasts for a long time, which is of positive significance for the early accumulation of deep formations.
