Comprehensive Application of Geophysical Prospecting and Drilling Technology to Detect Buried Faults in Quaternary Period
In this work,high-resolution seismic exploration,combined with transient electromagnetic and high-density resistivity detection,has been used to quickly and accurately delineate the location and buried depth of the upper breakpoint of Beiwu fault;Through cross fault joint profile drilling and geophysical logging,the late Quaternary stratigraphic characteristics and sequences are found out,the spatial position and fault displacement of the target fault are accurately located,and then the activity of the target fault is re-vealed. The interpretation results of comprehensive geophysical exploration technology are basically consis-tent with the drilling results,which proved that the application of comprehensive geophysical exploration and drilling technology in the detection of Quaternary concealed faults is effective.
