摘要
贵州赤水地区位于四川盆地南缘,迄今仅发现旺隆、太和2个气田和1个含气构造,未打开天然气勘探局面。近年来,通过对地质、钻井、开发及物探资料的综合研究,发现该区具有万米以上,有多套良好的生油气层系,初估生气量达2000亿×3;在地史发展中处于加里东期黔中古隆起和印支斯泸州古隆起的斜坡带,有利于气的运聚;区内存在东西向南北向两组构造,潜伏构造发育;已发现圈闭19个;钻井证实该区为具多压力系统、多产层。
Chishui area in Guizhou is located on the south border of Sichuan Basin. Its sedimentation thickness is over ten thousand meters. There are multi-sets of oil-gas generating beds in the area. Estimated reserves is 2×10 ̄(11)m ̄3. The geohistory is Caledonian-Qianzhong palaeohigh and Indosinian-Luzhou palaeohigh slop, Which is favourable for gas migraton and accumulation. There are two structures in the direction of longitude and latitude. Concealed structures are development. It is proved by drilling that the area is a multi-pressure,multi-payzone and multi-gas pool one. The surface distribution in the area is Jurassic and Cretaceous, Conservative conditions are very good. So it is possible to make a great progress of explorating gas in the area.
