摘要: 运用多种地质和测井方法对火山岩储层特征进行了研究.根据火山岩的岩性和电性特征,把枣35断块火山岩划分为2种大相和4种微相,并结合泥岩标志层和火山岩韵律组合对枣35断块火山岩喷发期次进行了划分.火山岩的储集空间分为4个大类、14种类型和5种储渗配置关系.该区火山岩孔喉特征以大孔喉为主,物性特征为高孔隙度和高渗透性.火山岩储层的储集性受多种因素的控制,重点探讨了岩相和构造应力的控制作用.

关键词: 枣35断块, 火山岩储层, 裂缝, 岩相, 喷发期次, 储集空间

Abstract: The characteristics of volcanic reservoir were studied with some geological and logging methods.Zao 35 Block was classified into two lithofacies and four microfacies on the basis of lithology and log features of volcanic rock in this area.The eruption periods of volcanic rock in Zao 35 Block were marked off by clay beds and volcanic formation rhythm.There are four categories of reservoir spaces including 14 types which formed five relationships between reservoir spaces and flow paths.The pores and throat of volcanic reservoir in Zao 35 Block are relatively broad,and the properties of volcanic reservoir in this area were characterized by high porosity and permeability.Many factors controlled the reservoir features of volcanic rocks.The lithofacies and tectonic stress were specially discussed.

Key words: Zao 35 Block, volcanic reservoir, fracture, lithofacies, eruption period, reservoir spaces
