摘　　要：火山岩岩性是划分岩相、研究储集空间类型及发育规律的基础。目前在火山岩岩性的识别方法中,对岩石物理以及如何综合利用电成像测井2方面尚缺乏深入探讨。在详细探讨岩石成分及其岩石物理性质的基础上,以大庆徐深气田为例,利用常规测井和电成像测井资料综合判断岩性。以此为基础,根据不同岩性组合和岩相的成因联系,划分单井火山岩岩相,并研究亚相的不同部位对于物性的控制作用。实践证明,该方法在大庆火山岩储层研究中取得良好的效果,同时,该方法对同类储层的研究具有一定的借鉴意义。Igneous lithology is the base of dividing lithofacies and studying on accumulation space types and growth history. At present, petrophysical property and FMI are two aspects which have been researched incompletely for the identification methods of vulcanite lithology. Based on the research on rock composition and petrophysical property, herein this article, suggestions are given, taking Xushen gas field in Daqing as an example, to use conventional logging and FMI to discriminate the lithology. According to the relative research and genetic relationship between different lithology association and facies, the igneous lithofacies of single well is defined and the control action of different subfacies＇parts to physical property is also researched. The field practice demonstrates that the application result of this method is very good in the research of igneous reservoir in Daqing, and this method can be taken as references for the research on reservoirs of similar type.
