摘　　要：火山岩气藏已成为油气勘探开发的重要领域之一。近年来,对准噶尔盆地滴南凸起火山岩气藏研究和滚动勘探开发工作取得了新的突破。综合研究认为准噶尔盆地滴南凸起火山岩气藏主控因素是:紧邻生烃中心的大型鼻状构造是气藏大规模成藏的基础;断裂与成藏期次的耦合是气藏形成最为关键的因素;良好的岩性及物性空间配置是油气成藏主要条件之一;构造控制火山岩气藏规模,砂体物性控制气藏局部边界。滴南凸起火山岩气藏富集模式可概括为"三控一体"模式,即源控(近源凹陷控制)、高控(古构造高点控制)、断控(气源断裂控制)以及气藏富集呈现"岩相体"富集特征。滴南凸起火山岩气藏成藏模式可为国内外同类气藏研究提供借鉴。Volcanic gas reservoir has become one of the important fields of oil and gas exploration and development.In recent years,new breakthroughs have been made in the research and progressive exploration and development of volcanic gas reservoirs in Dinan Salient of Junggar Basin.The comprehensive research suggests that the main controlling factors of volcanic gas reservoirs in Dinan Salient of Junggar Basin are:large nasal structure of volcanic gas reservoirs near hydrocarbon generation center was the basis of largescale gas reservoirs;The coupling between faults and reservoir forming period was the most critical factor in forming gas reservoirs;Good space allocation of lithology and physical properties wereone of the main conditions for hydrocarbon accumulation;Tectonic controlled the scale of volcanic gas reservoirs;Sand properties controlled partial boundary of gas reservoir.Enrichment mode of volcanic gas reservoirs in Dinan Salient could be summarized as "Three Controls and One Body"."Three Controls"were source control(sags near the source control),height control(high points of palaeotectonic control),fault control(gas source faults control);"One Body"meant that gas reservoirs were observed enrichment characteristics of"lithofaciesbody".The study on forming model of volcanic gas reservoirs in DinanSalient could provide good references for the study on similar gas reservoirs at home and abroad.
