摘要
By balanced section and buried history, tectonic evolution and the conditions of the free gas reservoir,the effects of the tectonic evolution to the free gas reservoir are analyzed. The accumulating model of the free gas is established in Qinshui basin. Through study, the conclusion is that in Yanshanian, the coalbed gas developed earlier would drift away to accumulate in some place of coal roof sandstone where the stress is lower because of the earth crust uplifting, and concentrate in the limbs of fold. In Xishanian, the folds developed earlier would be recreated because of the stress orientation.
