PORTABLE DEVICE AND SIMPLE METHOD FOR MULTI-PARAMETER COMPREHENSIVE TESTING OF CORE

A portable rock core multi-parameter comprehensive testing apparatus and testing method. The testing apparatus comprises a rock core wrapper and a parameter testing host machine; the rock core wrapper comprises a wrapping belt and parameter testing elements (8, 9, 10, 13) provided on the wrapping belt, the wrapping belt for wrapping a rock core comprises an inner layer and an outer layer, a sealed pressurizing air bag is provided between the inner layer and the outer layer of the wrapping belt, and the pressurizing air bag is connected to an inflating device by means of a rubber tube (1); the testing elements (8, 9, 10, 13) comprise a resistivity testing element (8), wave velocity testing elements (9, 10), and a strain testing element which are in signal connection with the parameter testing host machine. The apparatus can implement the multi-state geophysical parameter testing of rock cores having different diameters, wherein resistivity testing and wave velocity testing can be performed in the free state of the rock core and also in the axial compression state of the rock core, and strain testing is performed when the rock core is damaged by rock deformation under axial compression.
