济阳-临清东部地区石炭-二叠系煤系烃源岩二次生烃研究

济阳-临清东部地区上古生界石炭-二叠系煤系源岩是油气勘探的另一个重要领域。根据研究区沉积地层构造演化分析，不同的构造演化决定了不同的埋藏史演化；研究表明，中生代期间及新生代期间石炭-二叠系煤系烃源岩存在“二次生烃”过程，石炭系煤系烃源岩是研究区的主力烃源岩，二叠系的次之；济阳坳陷累计生烃量大于临清东部地区的累计生烃量。

Study on secondary hydrocarbon genesis of hydrocarbon rocks of Carboniferous to Permian coal series in east Jiyang to Linqing

The coal series souce rock is an important domain for oil and gas exploration in Carboniferous to Permian of upper Palaeozoic Era along Jiyang-Linqing.Based on the analyses of tectonic evolution of sedimentary formations in the study area,varied tectonic eolution dominated different burial history.The study demonstrated that there existed a "secondary process" in the coal serial hydrocarbon rock of Carboniferous System to Permian System during Mesozoic Era and Cenozoic Era.Carboniferous coal serial hydrocarbon rock was predominant hydrocarbon rock in the study area,Permian coal serial hydrocarbon rock was secondary dominant;the accumulative total hydrocarbon production in Jiyang depression exceeded that in the eastern area of Linqing.
