摘　　要：以大港枣园油田Z35断块火山岩裂缝性稠油油藏为例,利用取心井的岩心薄片鉴定、岩石化学分析等资料,结合岩心观察结果,对火山岩油藏岩石类型进行了划分。结合不同岩性的测井响应特征,建立单井相模式,将火山岩岩相划分为2个亚相和4个微相,并结合地震属性及开发动态资料,开展火山岩平面相分析与评价,进而阐述了岩相与油气分布的关系。评价结果表明,气孔玄武岩微相是该区火山岩油气藏的主要储集层。Taking the fractured condense oil reservoir of the igneous rock in Block Z35 in Dagang Zaoyuan Oilfield as the example, the rock types igneous rock of reservoirs were classified by using the information from the identification of sidewall coring thin section,rock chemical analysis,etc. and by combining the coring observation results.Combined the well logging corresponding features from different lithologies, the single phase mode was set up.the igneous rock phases were divided into 2 sub-phases and 4 micro-phases. And combining seismic attribution and dynamic development information,the plane phase analysis and evaluation for igneous rock was carried out.The paper stated the relationships between lithologic phase and distribution of oil and gas.It was showed by the evaluation results that the microphase in gas pocket basalt was the major reservoir for the area's igneous oil and gas reservoirs of the area.
