Description

Technical field:

[0001] The invention relates to a method for intelligently cleaning a movable and closed oil pipe and a pumping rod at an oil well operation site. Background technology:

[0002] At present, the oil pipes and sucker rods pulled out after oil well operations are generally placed on the pipe rack next to the wellhead manually. In order to avoid pollution, tarpaulin is generally laid on the bottom of the pipe rack, and then processed by two methods: one is to manually transport the oil pipes and sucker rods to the oil pipe factory for cleaning, and then transport a batch of cleaned oil pipes and sucker rods to the oil well operation site for use in the well; the other method is to manually clean the oil pipes and sucker rods on-site with steam or hot water, and use them in the well after the cleaning is relatively qualified. No matter which of these two methods is used, there will be problems such as environmental pollution (including secondary pollution), high energy consumption, low manual operation efficiency, poor safety and high operation cost. Summary of the invention:

[0003] In order to solve the above problems, the present invention provides a movable, closed type oil pipe and sucker rod intelligent cleaning method at an oil well operation site.

[0004] The technical solution of the present invention is: a method for intelligently cleaning movable and closed oil pipes and sucker rods at an oil well operation site, comprising a vehicle-mounted movable closed oil pipe and sucker rod cleaning device and a vehicle-mounted movable closed waste oil recovery, sludge separation and sewage recycling treatment and reuse device, the two of which can be connected by a pipeline; when the cleaning vehicle arrives at the oil well operation site, the vehicle-mounted movable closed oil pipe and sucker rod cleaning device automatically adjusts its level under the action of hydraulic support according to the sensors installed on itself according to the site road conditions, and then automatically extends the cleaning telescopic box and the folding transmission line located at the bottom of the box body in the direction of the wellhead, and automatically adjusts its level, while the cleaning device located at the top of the box body automatically drops to the bottom of the box body; when the oil pipe and the sucker rod are pulled out of the oil well and fall into the transmission line in sequence, After that, the following can be completed successively: the oil pipe is automatically lifted to the oil pipe cleaning position, and then automatically input into the cleaning box for cleaning of the inner and outer walls; the cleaned oil pipe and sucker rod are automatically output along the transmission line and automatically fall onto the finished product pipe rack, and can be used in the well; the sewage generated during the cleaning process is automatically separated by the vehicle-mounted movable closed waste oil recovery, sludge separation and sewage recycling treatment and reuse equipment, the separated waste oil and sludge can be pumped out regularly, and the separated sewage can be purified and heated before reuse; after the oil pipes are completely cleaned, the cleaning device at the bottom of the box will automatically move upward, the folding transmission line and the cleaning telescopic box will automatically be recovered in place, and various horizontal hydraulic supports will be automatically recovered, so that the whole set of closed cycle cleaning process can be automatically completed, and the next well cleaning operation can be carried out.

[0005] The beneficial effects of the present invention are:

[0006] 1. The mobile and closed intelligent system for cleaning oil pipes and sucker rods at the oil well operation site is easy to transport and can be delivered to the oil well operation site anytime and anywhere without lifting. It can also automatically adjust the level and pipe discharge position, which has overturned the traditional method of cleaning oil pipes.

[0007] 2. Since the cleaning of oil pipes and sucker rods is completed automatically in a closed environment without manual operation, environmental pollution (including secondary pollution) is completely avoided, safety hazards are eliminated, a large amount of labor costs are saved, and operating efficiency is greatly improved.

[0008] 3. Since the wastewater generated during the cleaning process can be separated and treated on site and then recycled, it greatly saves energy consumption and benefits the society. Description of the drawings:

[0013] When performing on-site cleaning operations, the inclination sensor 57 controls the movement of the support hydraulic cylinder of the work vehicle to automatically adjust the level of the work vehicle. The cleaning telescopic box 12 is extended under the action of the cleaning telescopic box hydraulic cylinder 13, and the flushing platform drives the gear assembly 33 to extend the oil pipe bridge 1 to the working position through the rack 32, and automatically adjusts the level through the adjustable support wheel 35. At this time, the oil pipe cleaning box 14 is lowered into place through the support guide rail 44 under the action of the cleaning box lifting hydraulic cylinder 36; when a piece of oil pipe pulled out from the operating oil well falls into the oil pipe bridge 1, the loading proximity sensor 58 is triggered to control the lifting platform 2 to lift the oil pipe bridge 1 to the position of the oil pipe inlet 38 through the lifting hydraulic cylinder 7 using the lifting rail 9. When the cleaning of the oil pipe triggers the proximity sensor 59, the drive sensor The transmission roller motor uses the transmission roller 5 to push the oil pipe into the oil pipe inlet 38. At this time, the lifting platform 2 falls to the pipe outlet position of the operating wellhead to receive the next oil pipe out of the well. After the oil pipe enters the oil pipe inlet 38, it first passes through the outer wall cleaning machine 37 and the outer wall cleaning machine water pipe 10 on both sides of the oil pipe inlet 38 for outer wall cleaning, and enters the pipe entry station 47, and then triggers the position photoelectric sensor 60. The pipe entry station hydraulic cylinder 45 drives the pipe entry station hydraulic cylinder pull rod 56 to flip the pipe entry station turning frame 46 to the inner wall high-pressure washing station 48, and triggers the trolley photoelectric sensor 61. At this time, the circulating water is pressurized by the high-pressure water pump 16 and then transported by the high-pressure water pipe 31 to the high-pressure washing nozzle 8 of the high-pressure washing pipe 6 on the washing platform 4. Driven by the moving trolley 3, it enters the inner wall flushing port 39 of the oil pipe to clean the inner wall of the oil pipe. After cleaning, the high-pressure flushing drives the trolley 3 to withdraw. After successively triggering the trolley stroke sensor A62 and the trolley stroke sensor B63, the pipe outlet station hydraulic cylinder 53 pushes the high-pressure flushing station hydraulic cylinder push rod 54 to flip the high-pressure flushing station pipe turning rack 49 to the pipe outlet station 52. The oil pipe cleaning box roller 15 sends the oil pipe from the oil pipe outlet 41 to the lifting platform 2. At the same time, the outer wall high-pressure nozzle water pipe 11 separated by the high-pressure water distributor 34 cleans the outer wall of the oil pipe again. After cleaning, the oil pipe triggers the unloading proximity sensor 64, drives the unloading roller motor to run, and the lifting platform 2 falls. The oil pipe is pushed to the pipe outlet support plate 42 by the pipe outlet hydraulic cylinder 40, and is pushed from The outlet pipe rack 43 rolls down on the pipe bridge rack and can be used in the well; the circulating water pump 18 pumps the dirty oil and sewage mixture generated during the cleaning process into the box of the vehicle-mounted movable closed dirty oil recovery, sludge separation and sewage recycling treatment and reuse equipment through the circulating water pipe 29 and the diffuser 30. Under the action of the floating oil separator 26, the separated circulating water 25 is filtered through the fence filter 24, the filter 21 and the alternating filter 19, and then transported to the high-pressure water pump 16 by the cleaning box water supply pump 20, and is recycled after being heated by the circulating water heater 17. The separated dirty oil 27 enters the dirty oil pool and is regularly discharged and recovered by the oil discharge pump 28. The sludge 23 settled at the bottom of the box is regularly discharged by the sludge discharge pump 22, and the entire closed cleaning process can be automatically completed.
