摘要: 川西中生代前陆盆地受龙门山造山作用控制,在中、深层次相应的沙溪庙组、千佛崖组等水进超覆沉积层序内,均发育大量利于天然气储集的有利相带。它们主要分布在前陆盆地内部受“古隆起”控制的相对稳定的斜坡地带。那里将成为川西地区天然气勘探的新领域。

Abstract: The Mesozoic Foreland Basin in West Sichuan area is controlled by Longmenshan orogenesis.In the transgressive overlap sedimentary sequences of medium-deep strata such as the Shaximiao Fm.,the Qianfuya Fm.,etc.,a great amount of favorable facies zones which are advantageous to the accumulation of natural gas are developed.They are distributed in the relatively stable slope regions within the Foreland Basin which are controlled by the paleouplift.There will become the new field of natural gas exploration in West Sichuan area.
