Experimental evaluation device of high temperature high pressure steam on rock core pollution

The invention relates to an experimental evaluation device of high temperature high pressure steam on rock core pollution. The experimental evaluation device is characterized by comprising an injection device, a thermostat, a condenser, a loop pressure control device, a back pressure control device and a data acquisition and processing device. A coiler is connected with a rock core clamper, the rock core clamper is externally provided with the thermostat, by the arrangement, kerosene or steam flowing through a rock core can be heated sufficiently to the temperature required by experiments, the temperature of the rock core clamper and the thermostat is maintained same, the temperature of the rock core in the rock core clamper can be calculated by the temperature of the thermostat, then the kerosene viscosity can be accurately conversed, the rock core permeability can be calculated, and the accuracy of the data of the rock core permeability can be effectively guaranteed. The experimental evaluation device can be widely used in the aspects of laboratory studies on pollution degree of steam injection exploitation on the rock core in the process of petroleum exploration and development.
