煤层气作为煤层的主要衍生烃类,其生成过程必然受煤层所处盆地的构造作用影响,从煤层的构造热演化特征可以得出煤化作用大致主要发生年代,煤层气的生成量,也可对是否有利于煤层气开发做出评估。含煤地层构造热演化史对煤层气生成、聚集具有影响,二次生烃对煤层气的生成具有重要作用,用构造热演化模拟的手段,可以反演含煤盆地所在区的沉积史和热演化过程,并研究它们与煤层气的关系,为煤层气的勘探指明了方向。本文结合国内学者相关研究,简述并概括了我国对于构造热演化模拟方法的相关研究。
As the main derivative hydrocarbon of coal seam, CBM production process is inevitably influenced by the tectonic function of the basin where the coal seam is located. From the tectonic thermal evolution characteristics of coal seam, it can be concluded that the main coal-generation period and CBM generation amount can also be obtained Whether it is conducive to the development of coalbed methane to make an assessment. The thermal evolution history of coal-bearing strata has influence on the formation and accumulation of coalbed methane. The secondary hydrocarbon generation plays an important role in the formation of coalbed methane. By means of tectonic thermal evolution simulation, the sedimentary history and heat of coal-bearing basin can be inverted Evolution process and study their relationship with CBM, indicating the direction of CBM exploration. Based on the relevant studies of domestic scholars, this paper briefly summarizes and summarizes the relevant research on thermal evolution modeling in China.
