摘要:

塔里木盆地具有形成大气田的地质条件:(1)多时代、多类型盆地叠加;(2)具多时代气源岩,气资源十分丰富;(3)多个大型古隆起、断裂、区域不整合为气运移聚集提供了良好场所;(4)有多时代、多类型的储盖组合;(5)既有油型气又有煤型气,以凝析气居多;(6)气藏(田)以构造和地层不整合类型为主.天然气主要分布在克拉通隆起,断裂带以及前陆盆地断褶带内.

关键词: 天然气, 克拉通盆地, 前陆盆地, 气源岩

Abstract:

Tarim Basin possesses the geological condition of forming big gasfields:1.superimposition of muti-age and multi-type basins;2.rich gas resources of muti-age source rocks;3.multi-age and muti-type caprock combinations;4.multiple palaeo-uplifts,faults and regional unconformities favourable for hydrocarbon accumulation;5.multi-type of gases with condensed gas in predominance;6.tectonic unconformity and stratigraphic uncorfornity being the main types of the gas pools and gas fields.The gases are mainly distributed in cratonic uplift,fault belts and fault-folded belts of foreland basin.

Key words: natural gas, craton basin, foreland basin, gas source rock
