摘　　要：EY-1井地区开展石炭-二叠系含煤地层生烃演化研究属国内首次。基于对EY-1井的石炭-二叠纪煤系的构造—埋藏史研究,结合有机质成熟度测试及分析,运用EASY%Ro数值模拟技术,研究了EY-1井石炭-二叠纪煤层及富有机质泥页岩的生烃演化历史。研究表明,石炭-二叠纪煤层及富有机质泥页岩曾发生了3次的生烃作用过程,海西-印支期,有机质发生一次生烃;燕山期共发生了3次埋藏作用,持续发生两次连续生烃作用;喜马拉雅期,受区域抬升作用影响,有机质停止演进。本区热演化在燕山运动中晚期达到生烃的高峰期,是油气资源快速成藏的主要时期,鄂尔多斯盆地EY-1井附近地区是西部石炭-二叠系油气资源勘探新的重要区域。It is the first time in China for EY-1well area to study hydrocarbon generation evolution of Carboniferous-Permian coal-bearing formation.Based on the research of the structure-burial history of coal measures of Carboniferous-Permian in EY-1well,combined with the testing and analysisng of organic maturity,the history of hydrocarbon-generation of the coal and organic-rich shale were studied in EY-1well.Research shows the coal and organic-rich shale of Carboniferous-Permian had occurred three times in the process of hydrocarbon-generation.The organic matter occurred one times in the process of hydrocarbon-generation in hercynian and indosinian.There were three times in the process of burial and two times in the continuous process of hydrocarbon-generation.Under the influence of regional uplift,organic matter stopped the evolution of hydrocarbon-generation.Thermal evolution of study area reached the peak of hydrocarbon-generation in the late of Yanshan Movement,which is the main period of rapid accumulation of oil and gas.The area near EY-1well in Ordos Basin is a new important area of Carboniferous-Permian oil and gas exploration in the western.
