摘要

With the deepening of exploration and development, volcanic gas shows the feature of separate reservoir of volcanic edifice. The non-homogeneous characteristics of volcanic rocks formation are obvious. For meeting the need of meticulous study of exploration and development, improving the level of volcanic gas reservoir comprehensive study and achieving a leap in understanding, in the Xujiaweizi depression dense well pattern-three dimensional seismic work area of Songliao Basin, the authors research the seismic volcanic edifice anatomy under the geological prior model constraint. Three kinds of volcanic edifices can be identified as layered, dome, and funnel-shaped. In order to achieve digital modeling and numerical simulation of volcanic edifice model, a two-phase superimposed composite volcanic edifice model is designed. Using drilling and core data, the acoustic characteristics of different lithological digital parameters are established.
