Abstract: A heat pump system, a heat management method and a vehicle are provided. The heat pump system includes an integrated heat exchanger integrated with a superconducting liquid flow passage and a refrigerant flow passage. The refrigerant flow passage is provided inside an on-board refrigerant circulation loop and is used for cooling and/or heating to adjust the temperature within a passenger compartment of a vehicle. The superconducting liquid flow passage is in communication with a motor heat dissipating conduit, for absorbing the heat generated by an on board motor and transferring the heat to the integrated heat exchanger by means of phase change heat transfer. The heat pump system can increase the energy utilization rate for the vehicle and reduce the allowable ambient temperature of the heat pump system.

Abstract: Provided is a carbon dioxide fluidity control device comprising, a sample preparation tank, a high-pressure stirring unit, a reciprocating plunger pump and a booster pump, wherein the stirring unit comprises one or more high-pressure stirring tanks, each provided with an atomizing spray probe and a piston, wherein a discharge port of the sample preparation tank is connected to the atomizing spray probe via a plunger pump, which is connected to the piston to push the piston to reciprocate; the booster pump is connected to the high-pressure stirring tanks to provide supercritical carbon dioxide to the high-pressure stirring tank; and a discharge port of the high-pressure stirring tanks is connected to an oilfield well group.

Abstract: Disclosed is a method for performing integral plugging control on water invasion and steam channeling of an edge-bottom water heavy oil reservoir. The method for performing integral plugging control on water invasion and steam channeling of an edge-bottom water heavy oil reservoir comprises the following steps: (1) selecting an oil reservoir; (2) arranging a huff-puff well; (3) performing steam huff-puff development; and (4) performing integral plugging control. An integral plugging control technology is used for the method, a high-strength nitrogen foam system is injected by means of well rows at different positions in the oil reservoir, and effective plugging walls are formed at different positions from the edge-bottom water to reduce water invasion and steam channeling.
