Preliminary investigation for electric conductivity structure of the crust and upper mantle beneath the Aershan volcano area;

Conventional well logging, gas logging and new well logging technologies can be used to evaluate the volcanic reservoir integratedly on the basis of full consideration of the characteristics of volcanic reservoir and formation heterogeneity.

It is hard to name and identify the volcanic lithology because it has many types.

There is mostly volcanic rocks in the reservoirs of Xushen gas field where the volcanic reservoir litholagy is complex and variable.

Application of neural networks technique based on crosspiot and multielement statistics to recognition of volcanic rocks;
