摘要: 煤层气的形成和赋存与煤变质的古地温场条件密切相关。本文利用镜质组反射率Ro,max反演煤变质的古地温场,从而揭示出我国晚古生代煤层气的生成和赋存,与我国板块运动及其对区域地温场的控制作用密切相关。Abstract: The formation and accumulation of coalbed gas are closely related to the paleogeothermal field of the coal metamorphism.This paper simulates the paleogeothermal field of the coal metamorphism with vitrinite reflectance(Ro,max),using methode of inversion.It is revealed that the formation and accumulation of coalbed gas of the Late Paleozoic in China are closely.related to the movement of plates in China and its control function to regional geothermal field.
