摘要： 分析了准噶尔盆地克拉美丽大气田石炭系古火山机构与天然气藏之间的关系。结果发现，研究区发育3个中心式地下古火山机构，其喷发中心分别位于滴西8井区、滴西27井区和滴西10井区。地下古火山机构中，近火山口次火山岩和近源相熔岩的储集性能较好、断裂较发育，其构造部位相对较高，是油气运聚的有利区带；凝灰岩与沉积岩、火山熔岩与次火山岩间互发育为气藏提供了良好的侧向遮挡条件，利于天然气成藏。

Abstract: The relationship between underground volcanic structure and Carboniferous gas reservoir in Kemaleili gas field of Junggar basin was analyzed. The results show that there are three central eruption underground ancient volcanic structures in this area. The eruptive centers of them are located in Dixi?8, Dixi?27 and Dixi?10 well areas. In the central eruption ancient volcanic structure, the subvolcanic rocks and proximal facies lava near the crater have better reservoir property and more developed fractures as well as relative high structure location, which are the favorable zones of the oil and gas migration and accumulation. The overlapped tuff/sedimentary rocks and lava/subvolcanic rocks provide good lateral sealing conditions for the gas reservoir, being beneficial to the gas accumulation.
