description The invention provides a resistance gradient test experiment device and method. The experiment device comprises a clamp holder, a resistance gradient test device and a controller, the compound live oil pipeline is used for filling compound live oil into one end of the clamp holder; the kerosene pipeline is used for emptying the fluid in the clamp holder; the pressure difference sensor is used for detecting the confining pressure of the clamp holder; the pressure detector is used for detecting the end pressure of the two ends of the clamping device; and the other end of the clamp holder is communicated with the gas booster pump. According to the method, the dissolved gas drive seepage resistance gradient in the tight reservoir core under different pressure conditions can be accurately tested, the control range of production pressure of reservoirs with different permeability can be obtained through analysis according to curve characteristics, and theoretical support is provided for depletion type effective deve
