中美页岩气成藏条件、分布特征差异研究与启示
Comparison and enlightenment on formation condition and distribution characteristics of shale gas between China and U.S.
摘要
Abstract
Shale gas in America mostly comes from thermogenic marine shales, and gas shales mainly dis-tribute in Devonian and Carboniferous of Foreland and Craton basins, while the buried depth is 1 500 ~ 3 500 m. Shales in China include 3 types; marine, transitional and lacustrine. Marine shales basically distribute in the lower Paleozoic of Aulacogen and Craton basins;organic-rich concentrated parts are steady-going, and thermal maturity phase and gas content are high, so the explorational prospect is the best. Transitional shales mostly distribute in Carboniferous-Jurassic of Foreland and Craton basins;there is no obvious organic-rich concentrated part, and gas content changes greatly, so the explorational potential needs to be proved. Lacustrine shales typically distribute in Mesozoic and Cenozoic of rift and Craton basins;organic-rich concentrated parts are thick and stable, and explorational potential is probably great in center of depression which reaches generating gas stage. It is forecast that shale gas exploration will take a long time and output will be 50 billion ~ 60 billion m3 in the future.关键词
