沁水盆地构造演化及其对游离气藏的控制作用
Tectonic Evolution of Qinshui Basin and Free Gas Reservoir Control
摘要
Abstract
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 analysed. 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. The free gas concentrated in earlier would migrate once more, so the place of free gas would change, but it is in the middle-high place away from the faults.关键词
