火山岩油气藏是一种特殊的油气藏类型，由于其储层岩性、岩相横向变化快，非均质性强，地质、 地震条件极为复杂，使得火山岩有效储层在平面展布、埋深、厚度和物性变化规律方面成为勘探的难点， 而常规地震反演技术又难以取得较好的效果。因此，该文针对上述难点，以准噶尔盆地西北缘红车断裂带 火山岩油藏为例，对其优质储层特征进行了精细分析，建立了该区的火山岩层序序列，并在此层序格架约 束下利用多属性地震反演技术预测了目标区火山岩优质储层的展布规律。最终，在研究区预测有利储层 面积达57.4 km²，积极推动了该区火山岩的油气勘探，应用效果显著。

As a special type of reservoirs, volcanic reservoir is characterized by fast lithology and lateral lithofacies change, strong heterogeneity, complex geologic and seismic conditions, which makes the recognition of effective volcanic reservoir difficult in the aspects of plane distribution, burial depth, thickness and properties changes, and it is difficult to obtain accurate prediction effect by conventional seismic inversion techniques. In viewof this difficulty, this paper analyzed the high quality volcanic reservoir in Hongche fault zone in the northwestern margin of Junggar Basin, established the volcanic sequence, and predicted the high quality volcanic reservoir distribution law by using multiattribute constrained seismic inversion technique. The predicted area of favorable reservoir in the study area reaches 57.4 km2. It will promote the oil and gas exploration of volcanic reservoirs in this area.
