A kind of heat exchanger for oil field

Abstract

The invention relates to the technical field of heat exchangers, and discloses a heat exchanger for oil fields, including a shell mechanism, a side sealing mechanism, a feed sealing mechanism, a feeding mechanism and a heat exchange mechanism; the shell mechanism includes a pipe body, and the The two ends of the pipe body are oppositely provided with a heat medium outlet nozzle and a heat medium inlet nozzle; the side seal mechanism includes a side seal cover, the top of the side seal cover is in a hemispherical structure, and the side seal cover A support seat is provided, and the side of the side seal cover is sealed and connected to the end of the pipe body through a flange; the feed sealing mechanism includes a feed seal cover, and the feed seal cover and the top end of the pipe body pass through a method The blue plate is sealed and connected, the top surface of the feed sealing cover is provided with a refrigerant liquid outlet, and the bottom surface of the feed sealing cover is provided with a refrigerant liquid inlet. The invention can use the high-temperature tail gas to heat the heat medium liquid, reduce its cooling rate, and further improve the heating efficiency of the oil, thereby reducing the loss of heat medium liquid resources.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a heat exchanger for oil fields. Background technique [0002] A large amount of associated gas will be produced in the process of oilfield exploitation. Most of the associated gases are methane, ethane, and propane. Generally, these associated gases will be burned by gas generators to make full use of energy. At the same time, the oilfield exploitation process It is also necessary to heat the oil through a heat exchanger. [0003] However, the existing heat exchangers for oil fields have the following defects in use: [0004] (1) The oil is simply heated by the heat source, which requires a large amount of heat source. At the same time, a large amount of high-temperature exhaust gas generated by the gas generator during power generation cannot be used, and is directly discharged into the air, resulting in a waste of a large amount of heat source; [0005] (2) In the pr...

Problems solved by technology

[0004] (1) The oil is simply heated by the heat source, which requires a large amount of heat source. At the same time, a large amount of high-temperature exhaust gas generated by the gas generator during power generation cannot be used, and is directly discharged into the air, resulting in a waste of a large amount of heat source;

[0005] (2) In the process of heating the oil, stagnation is easy to occur at the inflection point of the heat exchanger, which makes the flow rate of the oil slow and the heat exchange efficiency is low;

[0006] (3) In the process of oil supply, since the inlet and outlet of the oil are located at the same end of the device, mutual penetration is likely to occur, resulting in incomplete heating of the oil and uneven heating
