[0043] Preferably, a salinity meter 515 is provided on the mounting plate 1.

[0044] Preferably, a heating mechanism 6 is provided on the pressurizing pipe 501. The heating mechanism 6 includes a frame body 601, an electric telescopic rod 602, a moving frame 603, a second heating plate 604, an elastic rod 605, and a scraping blade 606. The frame body 601 is fixedly installed on the outer wall of the pressurizing pipe 501. The electric telescopic rod 602 is fixedly installed on the top of the inner wall of the frame body 601. The moving frame 603 is fixedly connected to the bottom of the output end of the electric telescopic rod 602, and sealing rings are provided at the bottom and top of the inner wall of the moving frame 603.

The number of scraping blades 606 is forty, and the forty scraping blades 606 are staggered at the top and bottom of the elastic rod 605.

[0046] Working principle: Filtered water is injected into the inner frame 503 through the water adding pipe, so that the filtered water is below the first connecting pipe 506. By starting the oil pump 4, the oil is extracted through the oil extraction pipe 2 and the oil extraction branch pipe 3. Then, the air pump 504 is started to send the external gas into the inner frame 503 first. The gas is filtered by the filtered water in the inner frame 503, and the impurities in the gas are left in the filtered water. The filtered gas will enter the pressure pipe 501 through the first connecting pipe 506 to pressurize the oil, thereby improving the oil extraction efficiency. By starting the first heating plate 511 to heat the filtered water, the gas entering the oil can be heated up, thereby preliminarily heating the oil, accelerating the fluidity of the oil, and thus increasing the oil extraction rate. At the same time, an inert gas is provided between the box body 502 and the inner frame 503, which can keep the filtered water warm and reduce the heat loss of the filtered water, achieving the purpose of energy saving. Open the control valve, and the oil enters the salinity measuring instrument 515 from the second connecting pipe 516 to detect the salinity of the oil. When the salinity of the oil is relatively high, the air pump 504 is turned off, and the water pipe 507 is connected to the external water source, so that clean water enters the inner frame 503. The clean water will drive the partition plate 510 to descend until the partition plate 510 contacts the water surface of the filtered water below. At this time, the partition plate 510 is below the first connecting pipe 506, and the clean water above the partition plate 510 enters the oil through the first connecting pipe 506 and the pressure pipe 501, reducing the salinity of the oil while continuing to pressurize the oil, thereby ensuring the stability of oil extraction. When the temperature of the oil is too low, by starting the electric telescopic rod 602 to drive the moving frame 603 to move downward, the second heating plate 604 is extended into the oil to heat the oil around the oil extraction pipe 2, thereby improving the fluidity of the oil around the oil extraction pipe 2 and accelerating the oil extraction speed. When the oil extraction is completed, the heating plate is retracted into the interior of the frame 601 through the electric telescopic rod 602, and the oil on the surface of the second heating plate 604 is cleaned by the elastic rod 605 and the scraping blade 606 to avoid affecting the subsequent use of the second heating plate 604. At the same time, the sealing plate 512 is removed to clean the filtered water in the inner frame 503 and remove the impurities generated by filtering the atmosphere in the inner frame 503.

[0047] Please refer to Figure 1-8, on the basis of the above embodiments, in another embodiment of the present invention, preferably, a conveying mechanism 7 is provided on the tubing string 2. The conveying mechanism 7 includes a motor 701, a auger 702, a rotating rod 703, a support rod 704 and a stirring rod 705. The motor 701 is fixedly installed on the top of the tubing string 2. One end of the auger 702 is fixedly connected to the output end of the motor 701, and the other end of the auger 702 passes through the top of the tubing string 2 through a bearing. The rotating rod 703 is fixedly connected to the bottom of the auger 702. One end of the support rod 704 is fixedly connected to the outer wall of the rotating rod 703. The stirring rod 705 is fixedly connected to the other end of the support rod 704.

[0048] Preferably, the number of the support rods 704 and the stirring rods 705 is four each, and they are arranged around the outer wall of the rotating rod 703.

[0049] Preferably, mounting blocks are fixedly connected to the mounting plate 1, and the number of the mounting blocks is four. The four mounting blocks are respectively arranged on the front and back sides of the mounting plate 1.

[0050] Working principle: By starting the motor 701 to drive the auger 702 to rotate, the oil can be transported more stably. At the same time, the rotation of the auger 702 will drive the rotating rod 703 to rotate, and then drive the stirring rod 705 to rotate through the support rod 704. The stirring rod 705 stirs the oil around the tubing string 2, improving the fluidity of the oil and making the second heating plate 604 heat the oil around the tubing string 2 more evenly.

[0051] The present invention provides an automatic pressurizing device for oil extraction equipment. There are many methods and ways to specifically implement this technical solution. The above are only the preferred embodiments of the present invention.
