The application discloses a carbon dioxide flooding miscible experimental device for oil and gas field development, including a bottom plate, a carbon dioxide gas tank, a lifting cylinder, a jacket, a horizontal plate, a rotating motor, a connecting rod, a cleaning plastic wire brush, a rotating sleeve, a socket, a rotating adjustment Rod, round sleeve, round rod, fixing nut, bolt, first reaction barrel, second reaction barrel, electric push rod, counterweight, power supply, wire, electromagnetic chuck, ring, electromagnet, iron movable sleeve, screw Springs, bent rods, sealing caps, pressure relief valve stubs, adjustable temperature heating tapes, regulating valves and air pipes. The advantages of the present application are that interval experiments can be performed through the first reaction barrel and the second reaction barrel. When one reaction barrel is performing an experiment, the other reaction barrel can be loaded with crude oil, and the state to be tested can also be dumped to remove the last experiment. The crude oil is loaded with new crude oil, and there is no need to stop the experiment to carry out the operation of pouring oil and loading oil, thereby improving the efficiency of the experiment.
Description
technical field [0001] The application relates to a carbon dioxide flooding miscible experimental device, in particular to a carbon dioxide flooding miscible experimental device for oil and gas field development. Background technique [0002] The carbon dioxide flooding technology is the technology of injecting carbon dioxide into the oil layer to improve the oil recovery rate of the oil field; in the initial contact of carbon dioxide with the crude oil in the formation, it cannot form a miscible phase, but under the conditions of suitable pressure, temperature and crude oil composition, carbon dioxide can form a miscible phase leading edge. [0003] In the prior art, the carbon dioxide flooding miscible phase experiment device conducts experiments by changing pressure and temperature; during the experiment, there is generally a lack of a bearing container for the crude oil to be tested, and the equipment to be tested is packed. of pouring and loading, thus affecting the ex...
