摘    要:储层岩性识别是火山岩油气藏勘探的基础。 通过对准噶尔盆地石炭系火山岩储层典型井的岩心观察,结合对岩石薄片及测井资料的详细分析,总结了火山岩的测井响应特征,提出了火山岩岩性测井识别方法。 该方法利用常规测井资料识别岩性,再应用成像测井资料识别火山岩的结构及构造,其中自然伽马、密度和声波时差是对火山岩岩性识别较有利的 3 种测井资料。 利用 GR-R t /AC 交会图可有效区分火山岩与沉积岩,在此基础上根据 GR-DEN 交会图与 GR-AC 交会图可区分出火山岩类型,最后结合成像测井图( FMI )可进一步识别火山岩的结构及构造特征。

关 键 词:沉凝灰岩  致密油藏  测井评价  条湖组  三塘湖盆地

Abstract:Reservoir lithology identification is the foundation of volcanic reservoir exploration. Based on core observation,combined with detailed analysis of thin sections and logging data, this paper summarized the logging response characteristics of volcanic rocks, proposed logging identification method of volcanic lithology. Conventional logging data were used to identify the mineral composition of volcanic rock, and imaging logging data were applied to distinguish the structure and texture of volcanic rocks, of which the natural gamma raylogging ( GR ) , density logging ( DEN ) and acoustic time logging ( AC ) are the more advantageous three logging curves to identify the lithology of volcanic rocks. The crossplot of GR-R t /AC can be used to effectively identify volcanic rocks and sedimentary rocks,and then the crossplots of GR-DEN and GR-AC can be applied to identify the volcanic rock types. Finlly,combinedwithFMI,thestructureandtexturecharacteristicsofvolcanicrockscanbefurtherdistinguished.
