摘　　要：介绍了阿根廷Cupen Mahuida海相火山岩气藏的基本地质概况。通过内乌肯盆地海相火山岩气藏勘探开发的成功实例,分析了Cupen Mahuida气田海相火山岩油气藏储层主要受沉积环境,成岩作用,构造运动等因素的控制。沉积环境决定了储层的分布与发育程度;成岩作用决定着储层的孔隙类型,次生溶蚀孔是储集油气的主要空间;构造作用是形成火山岩储层的基础,后期构造活动形成的裂缝在一定程度上改善了储渗条件。Introduced the basic geology of Cupen Mahuida marine volcanic reservoir in Argentina,Through the successful exploration and development of marine volcanic reservoir in Neuquen Basin,Analyzed the marine volcanic reservoir of Cupen Mahuida gas field was controlled by the depositional environment,diagenesis,tectonic movement and other factors.Depositional environment determined the distribution and degree of the reservoir;diagenesis determined the type of pore,secondary dissolution pore was the major oil and gas reservoir space;tectonic movement was the basis for formation of volcanic reservoir,The fracture caused by the latter tectonic activities,to some extent improved the porosity and permeability.
