摘要：
Well YT1 obtained industrial gas flow from the Permian volcanic breccia lava. This set off a wave of exploring volcanic rock in Sichuan Basin in 2018. Affected by the quality of seismic data, there are still some deficiencies in understanding volcanic mechanism and eruption model, resulting in the lack of eruptive formation in wells such as ZJ2 drilled later. Starting from the characterization of volcanic channels, a joint study of gravity, magnetic and seismic data was carried out, and a volcanic mechanism model was established and the plane distribution of volcanic mechanism was effectively predicted after characterizing the characteristics of fissure-type eruption from the volcanic rock along the shear zone between the basement faults in Sichuan Basin. Used to guide well TF2, the drilling result is remarkable. The method provides a new idea for exploring special lithologic bodies of volcanic rock in Sichuan Basin. © 2021, Editorial Department OIL GEOPHYSICAL PROSPECTING. All right reserved.
