Technical Field

[0001] The utility model relates to the field of oil production equipment, in particular to a well washing vehicle. Background Art

[0002] Well washing trucks are mainly used for cleaning, sand flushing, pressure testing and other operations of water injection wells during oil field production operations. They are mainly composed of chassis, auxiliary frame, lifting box, three-cylinder plunger pump, suction manifold, discharge manifold, high-pressure elbow box, water tank, etc. During the long-term water injection process, a small amount of mechanical impurities and oil contained in the water will accumulate in the stratum near the wellbore, reducing the water absorption capacity of the stratum, thereby polluting the water injection well, causing the water injection pressure to increase year by year, and even blocking the stratum, affecting the oil production of the oil well. In order to ensure normal water injection and achieve high and stable crude oil production, the water injection well must be cleaned regularly.

The connecting head 6 is a tapered opening that becomes larger when opening downward. The mounting frame 7 is rotatably mounted on the connecting head 6, and the interior of the mounting frame 7 is a plurality of sealed chambers connected to the surrounding areas. The nozzles 8 are provided in plurality and are respectively installed at the ends of the chambers of the mounting frame 7. The water suction pipe 9 is provided inside the water injection pipe 5, and the water suction pipe 9 runs through the entire water injection pipe 5, and the length of the water suction pipe 9 is longer than the water injection pipe 5. The water pump II 14 is installed on the top of the water tank 2, and the water suction port of the water pump II 14 is connected to one end of the water suction pipe 9, and the water outlet of the water pump II 14 is connected to the water tank 2, and the other end of the water suction pipe 9 runs through and is exposed outside the chamber of the mounting frame 7.

[0026] like Figure 3-Figure 5As shown, the inner wall of the connecting end of the connecting head 6 is a card slot protruding inward, and the card slot is covered with a waterproof sealing gasket. A connecting ring 71 is provided on the mounting frame 7, and the connecting ring 71 is fixedly connected to the top of the mounting frame 7. The outer wall of the top of the connecting ring 71 is a groove adapted to the card slot. The mounting frame 7 and the connecting head 6 are adapted to the card slot through the groove and the card slot buckle, so that the connecting head 6 and the mounting frame 7 can rotate relative to each other in a sealed connection, and the connecting head 6 and the mounting frame 7 can be disengaged by the groove and the card slot, so that the connecting head 6 and the mounting frame 7 can be easily replaced. The spray head 8 is detachably installed in the water outlet cavity of the mounting frame 7. The surface of the spray head 8 is provided with a texture that increases friction, and the spray head 8 can be conveniently disassembled or installed by twisting it.

[0027] like Figure 4 As shown, it also includes a ring gear 10, a motor 12 and a gear 13. A circle of openings is provided on the side wall of the connecting head 6. The ring gear 10 is fixedly installed on the outer side of the connecting ring 71. The ring gear 10 is located at the opening on the side wall of the connecting head 6. The motor 12 is installed on the outer wall of the connecting head 6. The gear 13 is arranged on the output shaft of the motor 12. The gear 13 and the ring gear 10 are meshed with each other. The motor 12 can drive the ring gear 10 to rotate through the gear 13, and then the rotating ring gear 10 drives the mounting frame 7 to rotate relative to the connecting head 6, so that the nozzle 8 installed on the mounting frame 7 can be rotated to spray water.

[0028] like Figure 4 and Figure 6 As shown, it also includes a shell 11, which is arranged on the outer wall of the connecting head 6. The shell 11 covers the outside of the motor 12. The motor 12 inside can be waterproofed by the shell 11. It also includes an outer frame 15, a cover plate 16 and a filter plate 17. The outer frame 15 is fixedly installed on the top of the water tank 2 and close to the water pump II 14. The suction pipe 9 is connected to the right side of the outer frame 15, and the left side of the outer frame 15 is connected to the water pump II 14 through a pipeline. An opening is provided on the rear side of the outer frame 15, and the cover plate 16 is hinged at the opening of the outer frame 15.

[0030] When it is necessary to use a well washing vehicle to clean the water injection well, the staff first drives the vehicle body 1 to the target well washing position and stops, then removes the mounting frame 7 from the vehicle body 1, pulls out the water injection pipe 5 from the vehicle body 1, and then connects the mounting frame 7 to the connecting head 6 through the connecting ring 71, and installs the nozzle 8 on the mounting frame 7 as needed. Then the staff can put the mounting frame 7 into the water injection well, and then activate the water pump Ⅰ3. The water pump Ⅰ3 first pumps the water in the water tank 2 into the connecting tube 4, and the pumped water enters the water injection pipe 5 through the connecting tube 4. Finally, the water that flows through the water injection pipe 5 will flow from the connecting head 6 into the chamber of the mounting frame 7, and the water injected into the chamber of the mounting frame 7 will be sprayed out from multiple nozzles 8. At this time, the motor 12 is activated, and the motor 12 will drive the gear 13 to rotate through the output shaft. The rotating gear 13 and the ring gear 10 mesh with each other and drive the connecting ring 71 to rotate. , the rotating connecting ring 71 synchronously drives the mounting frame 7 to rotate, thereby realizing that the multiple nozzles 8 on the mounting frame 7 can rotate to spray water, so that the dirt inside the water injection well can be effectively cleaned. When the nozzle 8 cleans the inside of the water injection well, the water pump II 14 is started synchronously, and the water pump II 14 will apply a suction force to the water suction pipe 9 to extract the sewage generated when the inside of the water injection well is cleaned outward through the end of the water suction pipe 9, so as to prevent the sewage in the water injection well from being directly sprayed out from the wellhead when the nozzle 8 injects a large amount of water into the water injection well for cleaning, thereby causing environmental pollution and waste of water resources. The extracted sewage will first flow into the outer frame 15, and the sewage in the outer frame 15 can be filtered and purified by the filter plate 17. The filtered and purified sewage will flow back to the water tank 2 under the action of the water pump II 14, thereby realizing the recycling of water resources and saving the workload of subsequent separate sewage treatment.

Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
