摘要
At present, the fluid identification technology of volcanic reservoir still on the develop stage, even more gas identification is a hotspot especially for during exploitation. There are 5 common fluid identification methods such as chart, curve overlap, 3 porosity combination, ratio and parameter etc. This paper will focus on how to identify fluid effectively using enlarge principle of statistic which avoid the complex rock component and put forward a new fluid identification skill for volcanic gas reservoir and take Yingtai gas field for an example.
