准噶尔盆地为我国4个中型气区之一,蕴藏着大量的天然气,纵向上含气层系多,从石炭系至新近系均有分布,而火成岩气田(藏)基本分布在西北缘的二叠系和腹部的石炭系.虽然准噶尔盆地火成岩天然气勘探时间较早,但受当时开发条件制约和市场需求的影响,没有较大的突破,直到2004年后,火成岩气田的开发才进入快速发展阶段.针对已开发火成岩气藏类型复杂多样、规模小、丰度低、物性差异大和配套技术不成熟等特点,并结合准噶尔盆地天然气勘探开发形势和火成岩天然气资源量,对天然气生产过程中的有利条件和制约因素进行了分析,提出了今后天然气开发目标和工作部署.

As one of the four middle scale natural gas abundant areas in China,Junggar basin is rich in natural gas distributed in several layer series from the Carboniferous to the Neogene,among which the volcanic gas fields(reservoirs)lie to the Permian in its northwestern margin and the Carboniferous in the hinterland.The volcanic gas exploration in Junggar basin began eadier,but no bigger breakthrough had been made until 2004 it entered into the fast developing stage,because of the restriction of the natural gas development conditions and the influence of market demand at that time.This paper analyzes the favorable conditions and restricted factors in process of gas production,integrated with the status of exploration and development of natural gas and the gas resources of volcanic reservoirs,in view of the characteristics of the complex types of the exploited gas reservoirs,the small scale,the poor abundance,the distinct heterogeneity and the lack of the matching technology,by which it proposes the targets and the working plan for gas development in Junggar basin in the future.
