Volcanic rock saturation calculation method considering altered clay

The invention discloses a volcanic rock saturation calculation method considering altered clay, which is characterized in that on the basis of natural volcanic rock plug sample rock electricity data and total rock analysis measurement data, the conductive contribution of altered clay minerals is evaluated by applying a Simmen model, and a saturation model more suitable for altered volcanic rocks is obtained. The stratum conductivity calculated by the new altered volcanic rock saturation model is matched with real measurement data, and when the new altered volcanic rock saturation model is applied to a well, a more reliable saturation evaluation result of the altered volcanic rock is obtained. The model experiment effect is good, and the method is more suitable for volcanic rock conductivity research. 本发明公开了一种考虑蚀变粘土的火山岩饱和度计算方法，该方法基于天然火山岩塞样岩电数据和全岩分析测量数据，应用西门度模型评估蚀变粘土矿物的导电贡献，得到更适合蚀变火山岩的饱和度模型。新蚀变火山岩饱和度模型计算得到的地层电导率与真实测量数据相吻合，在井中应用，获得了蚀变火山岩更可靠的饱和度评价结果。模型实验效果良好，更适合火山岩岩石导电性研究。
