火山岩储层构造–成因分类探讨

Abstract

火山岩传统分类强调岩类学内涵，与储集空间联系不紧密，不能满足油气勘探中储层研究的需要。基于火山岩储集空间类型、组合及其成因分析，归纳了6种与储集空间联系最紧密的因素，结合传统岩类学方案和前人认识，建立了油气勘探中火山岩储层分类新方案。 Traditional classifications of volcanic rock emphasize the connotation of petrography and poorly relate to reservoir spaces, which cannot meet the need for reservoir studies with respect to the oil and gas exploration. Based on the analyses of reservoir space types, combinations and genetics of volcanic rock, six factors that are closely related to reservoir spaces are summed up. Combining with the traditional classification schemes and previous knowledge, a new classification scheme of volcanic rock reservoir in oil and gas exploration is set up.
