摘　　要：近年来火山岩储层正逐渐成为石油勘探的热点，如何快速准确的确定火山岩的岩性越来越成为火山岩勘探的难题。本篇文章在对薄片、井壁取芯确定的取芯点上的岩性定名的基础之上，综合利用常规测井，ECS元素测井资料建立研究区的测井识别图版，在本区快速的利用所建立的识别图版完成对安山岩、流纹岩、闪长岩识别，再利用成像测井资料来区分开凝灰岩和沉凝灰岩，最终建立本区火山岩和侵入岩的岩性识别流程。In recent years volcanic reservoirs become the hotspot of oil exploration.How to determine the volcanic lithology fast and accurately is becoming a problem in volcanic exploration.In the paper,on the basis of naming the coring point determined through slice and side wall coring,the logging identification plate of interest area can be set up through comprehensive utilization of conventional logging and ECS element logging data,with which andesite,rhyolite,diorite can be identified and volcanic tuff and bedded tuff can be distinguished with imaging well logging data.Finally the lithologic identification flow can be established for volcanic and irruptive rocks in the area.
