| 摘 要： | 川西凹陷位于四川盆地西部,系晚三叠世卡尼期发展形成的一套沉积实体.它代表被动大陆边缘(须下盆)、陆内前渊盆地(须上盆)和陆内拗陷(J～K)的演化过程,因此它的形成与发展是与古特提斯洋盆的关闭有关.作者采用数学模拟的方法对其地史期的变化规律进行模拟,进而阐明川西凹陷天然气的生成、运移和聚散过程.

| Abstract: | Located in the west of Sichuan basin,the western Sichuan depression is a suite of sedimentary sequences developed in the Karnian of late Triassic,representing the evolutions of the passive continental margin(the basin under the Xujiahe Formation),intraconti-nental foredeep basin(the basin above the Xujiahe Formation)and intracontinental depression(J~K).Therefore,its formation and development are related to the closure of the Tethyan oceanic basin.The authors modelled on the varying patterns of the depression during its geological history,hence to clarify the formation,migration,accumulation and dispersion of the natural gas in the western Sichuan Depression. |
