| 摘 要： | 储层流体包裹体研究是认识油气运移、油气成藏的有效方法之一.通过对塔里木盆地克拉2气田克拉201井储层流体包裹体的系统取样研究,得到储层流体包裹体的四组均一温度:75～105℃,120～135℃,155～175℃,200～250℃.其中前三组与油气成藏有关,第四组及更高的温度可能与地下的热液活动有关.结合沉积埋藏史和热史的恢复,认为克拉2气田的成藏时间为11～2.5 Ma之间,即康村组至库车组沉积初期开始,到库车组遭受抬升剥蚀时停止.推测来自地下的高温热液可能对气藏起过重要的改造作用.

| Abstract: | The analysis of reservoir fluid inclusions is a useful method in studying hydrocarbon migration and entrapment.Four homogenization temperature groups, 75 ～ 105 ℃, 120 ～ 135 ℃, 155 ～ 175 ℃ and 200 ～ 250 ℃, are obtained, based on testing reservoir fluid inclusions systematically sampled from Well Kela-201 in Kela 2 gas field. The former three homogenization temperature groups are related to the hydrocarbon entrapment in Kela 2 gas field, and the last one or the higher temperatures may be related to the action of the hydrothermal fluid from the deep.In combination with the reconst ruction of the burial history and thermal history, it is shown that the time of hydrocarbon entrapment in Kela 2 gas field is 11 ～ 2.5Ma, beginning at the sedimentary time of Kangcun Formation to Kuche Formation and ending at the denudation time of Kuche Formation.The gas field could be altered by the action of hydrothermal fluid. |
