Description
Technical field
The utility model is a kind of elongated tubular inwall rust removing and contaminant releasing isolated plants such as petroleum machinery field oil pipe that are used for, and specifically, is a kind of oil pipe high-pressure water jet inwall rust removing and contaminant releasing cleaning device.
Background technology
Cleaning by High Pressure Water Jet is a high-tech cleaning technique that rises in the world in recent years.So-called high-pressure water jet, be that ordinary tap water is pressurized to hundreds of and even thousands of atmospheric pressures by high-pressure pump, then by special nozzle (aperture has only the 1-2 millimeter), with the concentrated current of one energy height of high speed (200-500 meter per second) ejection.This one weep has huge blow energy as pellet, and it can carry out steel plate cutting, cast cleaning, metal-derusting, more can remove salt, alkali, dirt and the various tamper of tube wall.The current that utilize this strand to have huge energy clean and are Cleaning by High Pressure Water Jet.
In oil exploitation, oil pipe is the higher crucial goods and materials of the essential a kind of quality requirement of Petroleum Production, and is very big to the influence of Petroleum Production.Oil pipe is carrying the conveying effect of oil gas, be in for a long time in the complicated well ore deposit, in the military service process of oil pipe, because crude oil composition complexity, in the course of conveying of oil gas, the complex salt of formation, rust, dirt often are attached to tube inner wall, even stop up oil pipe, having had a strong impact on the oil gas conveying, is one of insoluble the biggest problem in the oil exploitation.Because oil pipe belongs to elongated tubular, the highest with 23/8 " and 27/8 " oil pipe utilization rate, internal diameter only is φ 50.66 and φ 62.00mm, and length but reaches 6.1～9.7m, and general cleaning method is difficult to guarantee the rust removing and contaminant releasing quality.At present, for the dirty oil pipe of height, the domestic method that generally adopts high temperature incineration, chemical cleaning solution to handle is again carried out cleaning and descaling, mainly has following problem:
1, high temperature incineration can be removed the grease of high dirty oil pipe inside and outside wall, fusible mass such as cured.Main existing problems, the gas componant complexity behind the high temperature incineration, the exhaust-gas treatment difficulty is very big, and directly discharging is serious to atmosphere pollution; Simultaneously, because the influence of incinerator operating noise produces harm to surrounding enviroment and operator's hearing, be difficult to reach safety, environmental protection requirement; In addition, in the process of high temperature incineration, incineration temperature is difficult to control, burning often occurs or burns inadequate phenomenon, causes oil pipe to scrap or the secondary burning, has increased the production run cost.
2, chemical cleaning solution is handled again, can remove oil pipe inside and outside wall complex salt, rust.Main existing problems are, the method that Chemical cleaning uses strong acid, highly basic and chemical agent to soak more, and desalination, scale removal, rust cleaning time are long, can not reach desired effects.In addition, in the time of with chemical cleaning method desalination, scale removal, rust cleaning, the oil pipe body is also carried out partial corrosion, caused the tube wall uneven distribution, reduced body bearing strength and bonding strength.
3, automaticity, production efficiency are low.All there are the problem that automaticity is low, the time is long in high temperature incineration and chemical cleaning solution scale removal dual mode, are difficult to enhance productivity.
Owing to above reason, the oil pipe inside and outside wall is handled problems becomes the petroleum industry technical barrier, and the practical new technology of seeking a kind of high environmental protection, low damage is an urgent demand of the sector.
