CNIO3558648A discloses untethered well ground electrical method and microseism combined system and method for testing, the party
Method is the function realizing two kinds of instruments with a set of equipment, reduces equipment investment, and has played the excellent of two kinds of instruments
Point, it is possible to make up the multi-solution of a kind of detection method, monitor the trend of fracturing fracture more accurately.This side
Though method can provide accurate crack result on former electrical method or micro-seismic monitoring, again due to micro-in fracturing process
Seismic signal and electrical method signal faint, and cannot efficient solution determine the multi-solution of two kinds of exploitation methods.And this
Method, when two kinds of methods being measured simultaneously, does not accounts for the effect of intercoupling between geophysical field, number
It is to process respectively according to respective method during according to process, thus the mistake of experimental result can be caused.
