Analyses on integrated geophysical logging results in shallow hole across the Anninghe fault zone

Using the integrated geophysical logging technique, we measured resistivity, sonic velocity, spontaneous potential and natural gamma logs of two wells which were located in Mianning-Xichang segment of Anninghe fault in western Sichuan, and obtained the integrated physical parameters combining with coring data drilled around the drilled rock layer. The integrated logging interpretation results reflect the physical properties and lithological characteristics of the east and west sets of the Anninghe fault zone objectively, and reveal the physical properties variation of the P-wave velocity and the apparent resistivity of the fault zone, providing the basic data for research on material composition, media properties, structure and active state of the fault zone. Integrated geophysical logging technology is expected to become a new mean of monitoring dynamic variation of physical parameters near active fault zones.
