四川盆地西部中三叠统雷口坡组烃源岩生烃潜力分析OA北大核心CSCDCSTPCD
Hydrocarbon potential of source rocks in the Middle Triassic Leikoupo Formation in the Western Sichuan Depression
中三叠统雷口坡组是近年来四川盆地海相天然气勘探的重要层系之一.通过对川西地区雷口坡组钻井样品的有机地球化学分析,结合地震解释资料及沉积相资料,推测雷口坡组烃源岩主要分布在大邑—温江—彭州—广汉及孝泉地区,烃源岩厚度达250~350 m,有机碳含量为0.4%~0.6%.川西雷口坡组烃源岩形成于生物生产力较高、水动力较弱、海水循环受限、盐度较高、沉积物—水界面附近缺氧和沉积速率较低的沉积环境,有利于烃源岩有机质的保存.川西地区雷口坡组烃源岩有机、无机…查看全部>>
The Middle Triassic Leikoupo Formation in the Western Sichuan Depression is an important marine target for natural gas exploration in the Sichuan Basin in recent years. Geochemical analyses were made with rock samples from the Leikoupo Formation. Seismic interpretation and sedimentary data were studied. Source rocks in the Leikoupo Formation mainly distribute in Dayi, Wenjiang, Pengzhou, Guanghan and Xiaoquan. They are about 250-350 m thick, and have a TOC c…查看全部>>
