摘要
有关库车前陆冲断带天然气的许多基本地球化学指标相互矛盾,而且晚期成藏的天然气充注率很高。通过深埋水溶作用、储层流体包裹体均一化温度、储层油气演化史和水溶气脱溶成藏地质条件等4个方面的分析,认为库车前陆冲断带天然气的异常特征和高充注率与深部水溶气幕式(快速)脱溶聚集有关,并认为这是中国西部前陆区油气在喜山前陆强烈形成期通过断裂运移调整形成大中型气田的成藏规律之一。
Many basic geochemical indexes of natural gas are at the thrust\|uplist delt in Kuche foreland basin, and contrary late natural gas is fast injected. Singular characters and fast inject of natural gas are concerner with fast accumulation of deep water\|soluble gas by water\|soluble action in deep layer, homogenization temperature of fluid inclusions,evolutive history of petroleum and geological condition of water\|soluble gas formation.
