The rock resistivity testing technology under advanced simulated reservoir conditions is used to obtain the reservoir characteristic core with preserving the saturation of the original formation by using the pressure-tight closed coring technique. In the reservoir environment, the resistivity and temperature of rock, pressure , Saturation and other parameters. At the same time, the saturated crude oil and saturated water samples were analyzed comparatively, and the influence of different fluid saturated mediums on the rock resistivity test was discussed theoretically. Studying the variation law of rock resistivity in reservoir environment can not only calibrate well logging curves, but also determine the oil saturation of reservoirs by measuring the resistivity of saturated crude oil samples. This study, for the first time, applies core obtained from pressure-packed airtight coring techniques to resistivity testing techniques and opens up new areas of resistivity research.
