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
