Description

Technical Field

[0001] This invention belongs to the field of automatic oil pipe cleaning equipment, and in particular relates to an automatic on-site oil pipe cleaning device. Background Technology

[0002] Oil well tubing is an indispensable key component in oilfield production. The biggest factor affecting wells is tubing scaling and pump jamming. Due to long-term operation, scale accumulates inside the tubing, increasing the risk of pump jamming. This is especially true in areas with poor water quality, where insoluble scale such as sulfates and silicates are more likely to form (even boilers with strict sodium ion exchange water treatment can still develop insoluble scale such as sulfates), significantly reducing oilfield production capacity. Severely scaled tubing is difficult to clean and very inconvenient to maintain. In the past, tubing was usually transported back to the plant for cleaning and then transported back out, making it impossible to clean the tubing directly on-site. This resulted in a significant waste of time, manpower, and financial resources for tubing maintenance and cleaning. Summary of the Invention

[0003] In view of this, the present invention aims to provide an automatic on-site cleaning device for oil well tubing to solve the problem that existing technologies cannot directly clean the tubing on-site due to severe scaling in existing oil and water well tubing, and that the tubing needs to be transported back to the plant for cleaning, resulting in a long time wasted on cleaning and maintenance and causing economic losses.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic on-site oil extraction pipe cleaning device, comprising a moving mechanism, a cleaning machine, a cleaning pipe, a conveying mechanism, and an adjusting box. The conveying mechanism is mounted on the moving mechanism. The conveying structure includes two oppositely arranged cleaning pipe conveyor belts, forming a conveying channel between the two conveyor belts. A slide rail is provided on the moving mechanism along the vertical direction, and a slider is slidably connected to the slide rail. The adjusting box is rotatably connected to the slider. A cleaning pipe inlet is provided on one side of the adjusting box, and the other side is connected to the oil extraction pipe through a guide pipe. A sewage outlet is connected to the adjusting box. One end of the cleaning pipe is connected to the cleaning machine, and the other end of the cleaning pipe passes through the conveying channel and the cleaning pipe inlet of the adjusting box in sequence before entering the oil extraction pipe for cleaning.

[0005] Furthermore, an inlet pipe clamp and an outlet pipe clamp of the conveying mechanism are respectively provided on both sides of the conveying channel. Each of the inlet pipe clamp and the outlet pipe clamp of the conveying mechanism includes two rotating and oppositely arranged guide wheels, and the cleaning pipe passes through the two guide wheels.

[0006] Furthermore, the input end of the cleaning tube conveyor belt is connected to a motor.

[0007] Furthermore, a guide wheel is provided between the conveying mechanism and the regulating box, and the outer wall of the cleaning pipe abuts against the guide wheel.

[0008] Furthermore, both cleaning tube conveyor belts are connected to a conveyor belt adjustment mechanism, which adjusts the spacing between the two cleaning tube conveyor belts.

[0009] Furthermore, the inlet of the cleaning pipe is provided with an adjustment box inlet clamp, which includes two rotating and oppositely arranged guide wheels, and the cleaning pipe passes between the two guide wheels.

[0010] Furthermore, the moving mechanism is equipped with a control system, and both the cleaning machine and the conveying structure are connected to the control system.

[0011] Furthermore, the moving mechanism includes a vehicle body and a track mechanism, with two track mechanisms symmetrically arranged under the vehicle body.

[0012] Furthermore, the wastewater outlet is connected to an automatic wastewater recycling tank via a sewage pipeline.

[0013] Furthermore, the cleaning pipe is equipped with a nozzle, which has a spray angle of 45° backward.

[0014] Compared with existing technologies, the advantages of this invention are: This invention is an automatic oil tubing cleaning device that can solve the problem of severe scaling in the inlet of oil tubing, which wastes a lot of time and causes economic losses during cleaning and maintenance. It can quickly complete the cleaning and maintenance tasks without major repairs, saving time and reducing economic losses.

[0015] This invention can clean the inner wall of oil tubing, significantly improving the automation level of the equipment, enhancing ease of operation, reducing manpower consumption, and allowing the application device to be moved to different locations as needed, reducing transportation costs, alleviating the pressure of centralized cleaning, saving total cleaning time, and improving work efficiency. This device can provide an efficient and energy-saving working platform for cleaning oil tubing, enabling quick and convenient cleaning of the inner wall of the tubing, saving time and avoiding economic losses from major repairs.

[0016] An automated on-site tubing cleaning device features a highly automated cleaning process, enabling fully automatic on-site cleaning with fast speed, excellent cleaning effect, safety, high efficiency, simple operation, and environmental friendliness. The device is transported to the wellhead and positioned alongside the tubing at the well site. The adjustable box allows for height and angle adjustments, and the guide tube can move vertically and be angled to adapt to the height and angle of the tubing. It is suitable for all well sites. Wastewater generated during the cleaning process is discharged into an automatic wastewater recovery tank through the wastewater outlet, ensuring safe, environmentally friendly, and green cleaning operations.

[0017] An on-site automatic oil pipe cleaning device can travel to the opposite side of the oil pipe via a moving mechanism, control the height and angle of the regulating box, and through the control system, the speed and frequency of the automatic cleaning device can be set according to the actual scaling condition of the oil pipe, so that the cleaning pipe can move freely and clean smoothly. The cleaning pipe sprays high-pressure water jets to remove scale from the oil pipe, which has the characteristics of good cleaning effect, fast cleaning speed, high automation, safety, high efficiency, and green environmental protection.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0021] See Figure 1-2This embodiment describes an automatic on-site oil extraction pipe cleaning device, comprising a moving mechanism, a cleaning machine 1, a cleaning pipe 2, a conveying mechanism, and an adjusting box 10. The conveying mechanism is mounted on the moving mechanism and includes two opposing cleaning pipe conveyor belts 4 forming a conveying channel between them. A slide rail 14 is vertically mounted on the moving mechanism, and a slider 15 is slidably connected to the slide rail 14. The adjusting box 10 is rotatably connected to the slider 15. The height of the adjusting box 10 is adjusted by adjusting the position of the slider 15, and the angle of the adjusting box 10 is changed by rotating it. One side of the adjusting box 10 has a cleaning pipe inlet, and the other side is connected to the oil extraction pipe 12 via a guide pipe 11. A wastewater outlet 9 is connected to the adjusting box 10. One end of the cleaning pipe 2 is connected to the cleaning machine 1, and the other end of the cleaning pipe 2 passes through the conveying channel and the cleaning pipe inlet of the adjusting box 10 before entering the oil extraction pipe 12 for cleaning.

[0022] On both sides of the conveying channel are respectively provided an inlet clamp 3 and an outlet clamp 6. Both the inlet clamp 3 and outlet clamp 6 include two rotating, oppositely arranged guide wheels. The cleaning pipe 2 passes between the two guide wheels, guiding its direction within the conveying channel. The input end of the cleaning pipe conveyor belt 4 is connected to a motor 13, which drives the belt, causing the cleaning pipe 2 to move within the conveying channel. A reversing guide wheel 7 is provided between the conveying mechanism and the regulating box 10. The outer wall of the cleaning pipe 2 abuts against the reversing guide wheel 7, changing its direction to allow it to smoothly enter the regulating box 10. Both cleaning pipe conveyor belts 4 are connected to a conveyor belt adjustment mechanism 5, which adjusts the distance between them to accommodate cleaning pipes 2 of different diameters. The conveyor belt adjustment mechanism 5 can be a combination of guide rods, springs, and bolts. A regulating box inlet clamp 8 is provided at the inlet of the cleaning pipe. The regulating box inlet clamp 8 includes two rotating and oppositely arranged guide wheels. The cleaning pipe 2 passes between the two guide wheels, further stabilizing the path of the cleaning pipe 2 into the regulating box 10.

[0023] The mobile mechanism is equipped with a control system 16. Both the cleaning machine 1 and the conveying mechanism are connected to the control system 16. Through the control system 16, the speed and frequency of the automatic cleaning device can be set according to the actual scaling condition of the oil pipe. The cleaning pipe 2 is equipped with nozzles that spray high-pressure water jets to clean and remove scale from the inner wall of the oil extraction pipe 12, achieving fully automatic on-site cleaning. The nozzles have a 45° backward spray angle, enabling self-feeding. The wastewater discharge outlet 9 is connected to an automatic wastewater recovery tank via a sewage pipeline. Wastewater generated during the cleaning process enters the automatic wastewater recovery tank through the wastewater discharge outlet 9, ensuring safe, environmentally friendly, and green cleaning operations.

[0024] During operation, the device is first moved to the opposite side of the oil extraction pipe 12 via the crawler mechanism 18. The height and angle of the regulating box 10 are controlled, allowing the guide pipe 11 to move up and down and adjust its angle, raising or lowering it to align with the oil extraction pipe. The cleaning pipe 2 moves freely and cleans smoothly: one end of the cleaning pipe 2 is connected to the cleaning machine 1, and the other end enters the conveying channel formed by two cleaning pipe conveyor belts 4 via the guide wheel of the conveying mechanism inlet clamp 3. The motor 13 drives the cleaning pipe conveyor belts 4, moving the cleaning pipe 2 towards the regulating box 10. During this process, the outer wall of the cleaning pipe 2 abuts against the reversing guide wheel 7 to change direction, then enters the cleaning pipe inlet of the regulating box 10 via the guide wheel of the regulating box inlet clamp 8, and subsequently enters the interior of the oil extraction pipe 12 via the guide pipe 11. The nozzle sprays cleaning medium to clean the inner wall of the oil extraction pipe 12. The nozzle has a 45° backward spray angle and can achieve self-feeding during cleaning. Wastewater and impurities generated during cleaning are discharged into the automatic wastewater recovery tank via the wastewater discharge port 9 on the regulating box 10 and the sewage pipeline. After cleaning, the control system 16 controls the conveying mechanism to reverse. The cleaning pipe 2 moves in reverse sequentially through the inlet clamp 8 of the regulating box, the guide wheel 7, and the cleaning pipe conveyor belt 4 of the conveying mechanism, finally exiting through the guide wheel of the outlet clamp 6 of the conveying mechanism, completing the entire cleaning process. The cleaning process and the subsequent exit of the cleaning pipe 2 are all completed automatically by the cleaning equipment, requiring no manual operation. This device features a high degree of automation, fast cleaning speed, good cleaning effect, safety, high efficiency, simple operation, and environmental friendliness. It can quickly and conveniently clean the inner wall of oil pipes, saving time and avoiding the economic losses of major repairs.
