Description
Technical field
The present invention relates to high-pressure cleaning device.
Background technology
After oil well work certain hour, there will be tube inner wall and sucker rod fouling, hang wax, can crude output be affected like this, need well workover cleaning tubing and sucker rod.At present, each oil field of China general diesel oil boiler that adopts in cleaning heats into 120 DEG C ~ 130 DEG C steam water, utilizes pipe to be naturally ejected in oil pipe or on sucker rod by water vapour, makes grease, wax deposition dissolves to a certain extent outflow naturally.But a lot of oil pipe fouling is serious, and dirt is too thick, even that pipe plug is dead, slowly dissolve grease by vapours, the time is long, efficiency is low, and consumption diesel oil is many.For large, the inefficient cleaning equipment of this power consumption, a kind of electricity consumption is had to replace diesel oil, replace nature cleaning system with hydraulic press at present, the patent No. is that to provide a kind of take electricity as the cleaning device of the energy to ZL 201120281938.7 patent, with electric-heating water, with hydraulic press, hot water is boosted, then by hot water lance ejection out cleaning tubing, this device uses obviously more energy-conservation than original " oil field high temperature wax removal vehicle ", noiselessness, no operatton pollutes, and safety and environmental protection is obvious.But its problem is water temperature, and point molten compared with tube wall incrustation is low, the most high-temperature resistant 85 DEG C of general hydraulic press, the water of this temperature partly can only dissolve grease, powerful jet power (being no more than 30Mpa) be leaned on to remove grease, wax dirt, to the serious oil pipe of a small amount of fouling, sucker rod cleaning.Very long, same operating efficiency consuming time is not high.The hydraulic press of the domestic and international manufacturing all has heat-resisting speciality conflicting with pressure, and namely carry out coolant-temperature gage high, the pressure of generation is then little; Coolant-temperature gage is low, then can produce larger expulsion pressure, and this is the problem that hydraulic press temporarily cannot solve simultaneously.And institute's fouling melting temperature is generally in 90 DEG C ~ 110 DEG C intervals on tube inner wall, sucker rod, tack is extremely strong, washes such material, first apply 90 DEG C ~ more than 110 DEG C water-solubleization it, then remove it with having the strong expulsion pressure water yield.This requirement that namely will reach wax dirt melting temperature, have certain pressure again, is difficult to realize by hydraulic press self at present.
Summary of the invention
It is large that the object of the invention is to provide a kind of driving force, and water temperature is high, take electricity as the oil tube high-temperature high pressure cleaning device of the energy, thus improve cleaning efficiency, realizes the real safety of this work, energy-saving and environmental protection.
Technical scheme of the present invention as shown in Figure 1, a kind of oil tube high-temperature high pressure cleaning device, comprise a heater, thermal medium container, thermal medium increasing apparatus, reheat system and injection apparatus, the output of thermal medium container is connected with thermal medium increasing apparatus input, it is characterized in that the output of thermal medium increasing apparatus connects a hot high pressure medium second heating apparatus, the output of hot high pressure medium second heating apparatus connects injection apparatus.
Operating principle of the present invention is as follows: heater and thermal medium container (heating part) by media preheating to about 80 DEG C, by increasing apparatus, 80 DEG C of thermal mediums boostings are reached the pressure of 15 ~ 27Mpa(need of work again), the thermal medium that pressure is 15 ~ 27Mpa by reheat system again, temperature is 80 DEG C is heated to more than 110 DEG C, finally completes cleaning by injection apparatus again.The temperature of heat outputting medium of the present invention is more than 110 DEG C, pressure is at 15 ~ 27Mpa, improve temperature and the expulsion pressure of thermal medium, temperature exceed be attached to oil pipe, beam hanger dirt of waxing dissolves a little, oil pipe, beam hanger Fouling Cleaning can easily be fallen through spray gun by the thermal medium possessing ideal temperature and pressure, high temperature wax removal vehicle cleans 12 minutes average used times of oil pipe that a wax dirt blocks, and this device only uses 5 minutes, improves effect 41%.The power consumption of the every washing and cleaning operation of apparatus of the present invention (120 pipes) well flatly, higher temperatures wax removal vehicle saves about 1800 yuan, and efficiency and economic benefit significantly improve, and be one is desirable oil pipe cleaning device.
Embodiments of the invention are provided below in conjunction with accompanying drawing.
