The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 5, an embodiment of the present application discloses a paraffin removal vehicle, which can be applied to a well-flushing paraffin removal operation. The disclosed paraffin removal truck includes a truck chassis 100, a heating device 200, a first pressurizing device 300, and a manifold system.

The chassis 100 is a base mounting part of the paraffin removal truck, and can provide a mounting base for the heating device 200, the first pressurizing device 300, the manifold system and the like, and the chassis 100 can also be used for enabling the paraffin removal truck to move to change the operation place. Alternatively, the vehicle chassis 100 may be fuel powered, electrically powered, or a hybrid fuel and electric drive. Alternatively, the heating device 200 and the first pressurizing device 300 are respectively disposed on the chassis 100, and the chassis 100 can carry the heating device 200, the first pressurizing device 300 and other components to travel, so as to perform work on different places.

Manifold systems are used to connect components and to transport fluid media. The manifold system comprises a liquid inlet pipe 910, a liquid outlet pipe 920 and a first connecting pipe 930, wherein the liquid inlet pipe 910 is connected with the heating device 200, the heating device 200 and the first pressurizing device 300 are connected through the first connecting pipe 930, and the liquid outlet pipe 920 is connected with the first pressurizing device 300. Thus, the liquid inlet pipe 910, the heating apparatus 200, the first connecting pipe 930, the first pressurizing apparatus 300, and the liquid outlet pipe 920 are connected in sequence along the flowing direction of the fluid medium, respectively. Based on this, the fluid medium may flow into the heating device 200 through the liquid inlet pipe 910, and the fluid medium is heated by the heating device 200 to reach a preset temperature, and then the heated fluid medium flows into the first pressurizing device 300 through the first connecting pipe 930, and is pressurized by the first pressurizing device 300 to reach a preset pressure, and then the pressurized fluid flows out through the liquid outlet pipe 920, so that the fluid medium with high temperature and high pressure is injected into the well to realize paraffin removal operation, and at the same time, the blockage removal operation may also be realized.

Based on the above arrangement, in the embodiment of the present application, the fluid medium is preferentially heated and then pressurized, so that the high-pressure fluid medium formed after pressurization is effectively prevented from flowing into the heating device 200, and therefore, the pressure of the fluid medium is not limited by the heating device 200, so that the fluid medium can reach a higher pressure, and the requirement of the deep well for the higher pressure of the fluid medium is met. In addition, the wax removal vehicle can freely move through the vehicle chassis 100, and operations in different places can be realized, so that the scheduling time can be saved, and the operation efficiency can be improved.

Referring to fig. 2, in some embodiments, the manifold system further includes a first branch pipe 950, one end of the first branch pipe 950 being connected to the first connection pipe 930, and the other end of the first branch pipe 950 being connected to the outlet pipe 920. Based on this, fluid medium can flow into through feed liquor pipe 910 to flow to heating device 200 and heat, in order to reach preset temperature, and then the high temperature fluid medium that passes through the heating flows to drain pipe 920, and flows out through drain pipe 920, thereby can be used to the cleaning operation of ground pipeline and equipment.

It should be noted here that the above process can produce high temperature liquid, and the high temperature liquid is not pressurized and thus is not used for injecting into a well to perform paraffin removal and blockage removal operation, but rather, the high temperature liquid is produced so as to be used for cleaning some components (such as ground pipelines, equipment and the like) and thus ensure the cleanness of the components. In addition, in order to switch the flow path of the fluid medium, control valves may be provided on the side of the first connection pipe 930 near the first pressurizing means 300 and on the first branch pipe 950, respectively, in which case the on/off of the side of the first connection pipe 930 near the first pressurizing means 300 and the on/off of the first branch pipe 950 may be controlled by the control valves, respectively.

The second pressurizing device 400 is disposed on the liquid inlet pipe 910. Based on this, the second pressurizing device 400 is located at the upstream of the heating device 200, so that the fluid medium pressurized by the second pressurizing device 400 flows into the heating device 200, and then flows through the first pressurizing device 300 to be pressurized for the second time, so that the fluid medium reaches a higher pressure.

In view of the fact that the heating device 200 itself is not subjected to too high a pressure, the second pressurizing device 400 may be a low-pressure pressurizing device. Alternatively, the second pressurizing means 400 may be a centrifugal pump. Based on this, can realize that the low pressure supplies liquid operating mode demand, and can cooperate with first pressure device 300, effectively alleviate the not enough problem of first pressure device 300 imbibition ability to guaranteed that first pressure device 300 can not appear the phenomenon of resorption, prolonged first pressure device 300's life.

Based on this, the fluid medium that is primarily pressurized by the second pressurization device 400 may also flow to the first connection pipe 930 through the second branch pipe 960, and then flow into the first pressurization device 300 for secondary pressurization, and finally flow out through the outlet pipe 920.
