摘    要:以松辽盆地深层徐家围子断陷兴城和升平火山岩气藏为解剖对象,研究了火山岩体对火山岩气藏的各种控制作用,包括对火山岩气藏的纵-横向分布、气-水关系、盖层、气藏类型等多个方面的控制。正是由于其控制作用,火山岩气藏分布纵向延伸空间大,在4000~5000m深度仍能发现气藏,并具有多套气藏叠置的特征;横向上呈串珠状分布的特点。火山岩气藏气-水关系十分复杂,主要受火山岩体及火山喷发期次的控制。每个火山岩体具有独立的气-水系统,而同一火山岩体及同口井中则存在多套气-水系统。火山岩气藏具有自储、自盖的特征,从而使气藏对区域盖层要求弱化。火山岩气藏的类型总体有4大类,以构造-岩性复合气藏为主,主要受岩性控制,在构造高部位聚集;而低幅背斜-岩性复合气藏则是火山岩气藏特有的一种气藏类型,它是火山喷发过程中形成的一种特殊的背斜构造。

关 键 词:气藏特征  火山岩体  火山岩气藏  松辽盆地

Abstract:The research documented in this paper takes the Xingcheng and Shengping volcanic reservoirs in the Xujiawuzi fault depression in the deep of the Songliao basin as study targets. It focus on the controlling effect of the volcanic bodies upon the horizontal and vertical distribution,waterˉgas relationship,caps,pooling types of the gas reservoirs. Thanks to the volcanic bodies,these reservoirs have wide vertical distributions and can occur in a depth up to 4000 to 5000 meters and show features of vertical superimposition of multiple gas reservoirs and lateral beaded distribution. The gasˉwater relationship in the volcanic gas reservoirs is complicated and controlled by the volcanic bodies and eruption periods. Each volcanic body owns isolated gasˉwater systems,but with initor within the same well,there may be several gasˉwater systems. Volcanic gas reservoirs feature in selfˉaccumulation and selfˉsealing and therefore regional seals are not the major condition for hydrocarbon pooling. In general,there are four types of volcanic reservoirs. Among them,the structuralˉlithologic complex gas reservoirs are predominant and controlled mainly by lithology and occur mostly at the structural highs,while the lowˉamplitude anticli nalˉlithologic complex gas reservoirs can only be found in volcanic rocks. They are harbored in a kind of specific anticline formed during volcanic eruptions.
Keywords:gas reservoir characteristic  volcanic body  volcanic gas reservoir  Songliao Basin
