摘要
利用盆地模拟系统，用镜质体反射率反演法进行了热史的恢复，计算了塔里木盆地寒武系、下奥陶统、中上奥陶统、石炭系等古生界气源岩在不同地质历史时期的镜质体反射率．建立了塔里木盆地轮南地区、满加尔凹陷、阿瓦提凹陷和塔中地区古生界气源岩的热演化史，着重分析了各地区古生界气源岩的成气贡献，并从热演化的角度分析了气源岩的生气高峰．研究表明，塔里木盆地天然气的主要来源是下古生界烃源岩．
By means of vitrinite reflectance inversion of numerical simulation for basin, some data of vitrinite reflectance of gas source rock are obtained in different geohistory,such as cambrian,down_ordovician,up_middle_ordovician and carboniferous source rocks of palezoic in Tarim basin. The thermal geohistory of gas source rock in palezoic is reconstructed in areas of Lunnan, Manjiaer,Awati and Tazhong.Both the gas_generating peak and the potential of gas source rock are analysed. The natural gas of Tarim basin is mainly generated from hydrocarbon in palezoic group.
