摘　　要：随着常规油气勘探开发的加深,潜力局限性愈加明显,常规油气储量已经不能满足需求。火山岩油气藏作为勘探界的一股清流,且有较好的前景与潜力浮现,受到了众多地质研究者的关注。岩性、岩相特征,以及不整合关系诸多因素控制了火山岩储层的优劣性,使得火山岩储层有较沉积岩储层更加复杂的特征。因而,在火山岩储层的勘探开发过程中,对于火山岩的岩石结构、岩石类型的准确识别是储层评价有效性的关键,鉴于此,本文归纳了火山岩的测井响应特征:火山岩在常规测井曲线的响应特征,ECS测井针对化学成分复杂的火山岩的识别特征。with the deepening exploration and development of the conventional oil and gas, potential limitations became apparent and conventional reservoir has can't meet the demand. Volcanic rock reservoirs as a new way of exploration industry, and have good prospects and potential with many geological researchers' attention. Characteristics, lithology, lithofacies and unconformity relation factors controlled the superiority and inferiority of volcanic rock reservoir, which makes the volcanic reservoir is more complex compared with the sedimentary reservoir. Therefore, in the process of exploration and development of volcanic rock reservoir, the volcanic rock structure and accurate recognition of rock type is the key to effective reservoir evaluation. in view of this, this article summarizes the logging characteristics of volcanic rock: the characteristics of conventional logging curve, ECS logging to deal the rocks of complicated chemical composition, And FMI logging on the response of the structure characteristics in its unique way to identify volcanic rock lithology.
