[0069]The present invention will be further described in connection with the accompanying drawings:
[0070]The present invention provides a method and system for determining the characteristics of electrical response in different wet states of the core, including: according to the logging data and related assay analysis materials, it is determined that the well section that may be the oil and humid reservoir, carrying the drilling Get the target core and collect the formation of the formation of the formation; the saline water of the specific mineralization is configured according to the experimental needs, and the density of crude oil and brine and the nuclear magnetic resonance T of the crude oil are measured.2Spectrum; three treatment of oil water drover after removing oil in the target core, washing oil, washing water, and the oil water drover after washing oil, that is, modified. Wetten state by measuring the binding water state nuclear magnetic resonance T2The resulting USBM ind...
