| 摘 要： | 对文安斜坡石炭—二叠纪(C—P)煤系特征,尤其是煤的煤岩显微组分组成和煤及煤的各显微组分的元素组成特征的研究表明,本区煤中镜质组含量占绝对优势且较富氢。本文还研究了新生代该煤系的再次埋藏和该区下第三系岩浆活动以及煤系中多层辉绿岩侵入的热力作用对其成熟度的各自影响程度,认为本区已发现的煤成油气藏大体分布在平均R_0为1.0％～2.0％的苏桥地区,与早第三纪岩浆活动有密切关系。岩浆热力影响有效地促进了煤系烃源岩的热演化和成烃转化,而破坏作用则不大。

| Abstract: | The characteristic of C -P coal -bearing formation in Wenan slope , particularly the macerals of coal rock and the elements of the coal and its macerals are studied .The results show that the coal seams mainly consist of hydrogen-rich vitrinite . In addition, the paper reports the C -P coal -bearing series being buried again in Cenozoic era and the various extent effect of thermal power of magmatic activity on coal maturity in Early Tertiary , which show that the oil-gas pools of coal generating lie in Suqiao area with an average R0 between 1.0% and 2.0% , and closely related to the magmatic activity in Early Tertiary . The magamtic thermal power makes an important effect on the thermal maturation and hydrocarbon -generating of the source rocks of coal formation , but the destruction of magmatic metamorphishm on the source rocks of coal formation are not obvious or minor . |
