By taking gas geochemistry and thermal maturity of natural gas as well as thermal maturity of source rock for the typical gas pool in the northern Qaidam basin,we suggest that the general characteristics for the natural gas pools is late hydrocarbon generation and late hydrocarbon accumulation,in combination with thermal history of source rock and fluid inclusion data.Thus,the late trap formed in the late Himalayan period will be favorable gas exploration target.This achievement will greatly guide gas exploration in the Eboliang structure zone and give a sample for late trap gas exploration in the northern Qaidam basin.
