    摘要:

    上奥陶统五峰组(O3w)—下志留统龙马溪组(S1l)是川东南地区页岩气勘探开发的重要层系。利用钻井、测井、地震及分析化验等资料,明确了川东南地区具有较好的页岩气成藏条件。该区位于深水陆棚有利沉积相带,优质页岩(TOC>20%)厚度大,介于20~50 m之间,呈北东—南西向展布,有宜宾—泸州和石柱—建南两个厚度中心,有机质丰度高(平均TOC>20%),热演化程度适中

    Abstract:

    Objective: Upper Ordovician Wufeng Formation — Lower Silurian Longmaxi Formation s are important stratum for shale gas exploration in southeast Sichuan basin. Method:Shale gas reservoirforming conditions are good in this area according to field geological investigation, well and logging data comparison, seismic data interpretation and test data analysis et. al.Results:Study area is located in deepwater shelf with large thickness of high quality shale (20~50 m). There are two thickness centers of Yibin—Luzhou and Shizhu—Jiannan from northeast to southwest. TOC content of shale is generally higher than 2.0%. Maturation is medium (2.0%
