We have successfully forecasted the planar distribution of volcanic rocks. Furthermore, we have applied wave impedance inversion which is based on geological model, by using of this method to identify the reservoir of the volcanic rock and forecast the reservoir transverse distribution and trap the containing gas area. This method which combined geological, logging, seismic and many other informations into a model and realized the combination of all kinds of formations in the model space, has its particular advantages compared with conventional methods, it has improved using quantity of inversion information, precision of information match and credit of the results of inversion.
