川南是四川天然气主要产区之一,经二十多年的勘探、开发与综合研究,积累了大量成果。近年来,阳深1井于古生介奥陶系宝塔灰岩钻遇良好的气显示,相国寺气田在中石炭系获新的高产气藏,进一步展示了川南油气勘探向纵深发展的远景。笔者等运用地质力学方法,对川南构造体系与含油气关系进行了研究,提出以下认识。 Sichuan is one of the major natural gas producing areas in Sichuan. After more than 20 years of exploration, development and comprehensive research, Sichuan has accumulated a great deal of achievements. In recent years, the well of Yangshen-1 well drilled in the Paleo limestone of the Paleozoic Ordovician shows that the Xiangguosi gas field has obtained new high-yield gas reservoirs in the Carboniferous and further demonstrates the prospect of deep-seated hydrocarbon exploration in southern Sichuan. The author applied the method of geomechanics to study the relationship between the structural system of south Sichuan and oil-bearing gas and put forward the following understanding.
