High temperature and high pressure cleaning machine, hot water and high pressure cleaning machine for oil field tubing cleaning

1、 The repair and recycling of oil field tubing and drill pipe is an important measure to reduce the comprehensive cost of production Improving the repair quality of tubing and rod can ensure the quality of oil well operation, prolong the period of pump inspection, reduce the rework of operation and reduce the operation cost Cleaning, as the first procedure in the tubing repair inspection line, can effectively remove the oil, wax and scale on the inner and outer walls of the tubing rod, ensure the cleanness of the repaired tubing rod, and create clean conditions for other procedures There are two main technologies for tubing cleaning: high-pressure water jet and hot boiling In winter, due to the large amount of recovered tubing in the well and the thick and hard wax layer, hot boiling is generally used, and high-pressure water jet cleaning is used in other seasons In addition, due to the scaling on the inner wall of the tubing, the tubing of the whole well was often scrapped in the past Using high-pressure water jet cleaning technology to clean the inner wall of oil pipe has obvious effect of scaling, which can effectively reduce the waste of oil pipe 2、 High pressure water cleaning 1 Selected equipment: Italy aoweeks group "owex" high temperature and high pressure cleaning machine, hot water and high pressure cleaning machine topgun250 (the equipment is represented by Beijing Zhongkai Yingchuang Petroleum Equipment Co., Ltd.) 2 Technical parameters of high temperature and high pressure cleaning machine and hot water and high pressure cleaning machine: pressure: 30-250bar temperature: 150 ℃ constant temperature flow: 1260l / h power: 11kw 3 Principle and characteristics of topgun250 high temperature and high pressure cleaner and hot water high pressure cleaner The principle of topgun250 high temperature and high pressure cleaner and hot water high pressure cleaner is to pump out high pressure water with high pressure pump and heat it to 150 ℃ high temperature hot water steam through heating coil, When it reaches the nozzle through the pipe, the nozzle converts the water with high pressure and low flow rate into the jet with low pressure and high flow rate, which impacts the surface of the cleaned part in a positive or tangential direction; the high-temperature hot water steam makes the oil and grease on the surface of the object dissolve rapidly Once the scale layer is penetrated, the fluid wedges between the scale layer and the surface of the cleaning part, so that the scale layer falls off and the surface of the cleaned part is exposed Layered or porous scale is easy to break, because the jet impingement can hit a hole and form an internal pressure below the surface of the scale layer, which causes the upper scale layer to crack In many jet operations, the presence of crushed particles in the jet can help to produce more particles 4 Structure of topgun250 high temperature and high pressure cleaner and hot water high pressure cleaner Topgun250 high temperature and high pressure cleaner and hot water high pressure cleaner are mainly composed of high pressure plunger pump, power part, heating part, nozzle, high pressure hose and working accessories (1) high pressure plunger pump is the main part of Zui in high pressure water jet cleaning device Ceramic material is selected to be resistant to high temperature and wear, thus increasing the service life of high-pressure pump (2) the power source of the power part is 11kw motor The factory power supply of 380V 50Hz is adopted, which is very convenient to use The motor is a low-speed motor of 1000 rpm, which effectively reduces the wear of high-pressure plunger pump Continuous working time can reach more than 10 hours (3) The heating part of the heating part is a double-layer heating furnace plate made of stainless steel seamless steel tubes more than 50 meters long It can make the cold water fully heated, with the thermal efficiency of more than 95%, so as to achieve a constant water temperature of 150 ℃ (4) the high-pressure hose is connected between the high-pressure water pump and the nozzle by a 10 meter long high-pressure hose The high pressure hose is composed of inner tube, reinforcing layer and outer skin The inner pipe carries water, and the reinforcing layer improves the strength of the inner pipe to withstand high pressure, while the outer skin plays a protective role to prevent corrosion and mechanical damage High pressure hose and reinforcing layer are woven with steel wire, generally 2-3 layers (5) high pressure water from the spray gun, nozzle and working accessories flows through the hose, Zui, and then reaches the spray gun, nozzle and working accessories The nozzle transforms the water with high pressure and low velocity into the jet with low pressure and high velocity Under certain conditions, the cleaning effect mainly depends on the accessories and nozzles of the high-pressure cleaning device The general nozzle is made of a variety of special metals In order to produce water jet for cleaning, cylindrical and flat nozzles are generally used Because of the different structures and functions of the two nozzles, the range of the cylindrical nozzle jet is far, but the action area is small, while the range of the flat nozzle jet is short, but the action area is large 3、 Oil pipe cleaning process 1 Cleaning of outer wall of oil pipe: 2 Cleaning of inner wall of oil pipe: the inner and outer walls of oil pipe are attached with oil dirt, oil dirt and wax, which are generally difficult to clean The old process generally adopts the method of alkali boiling, which is slow, high cost, low efficiency and poor cleanliness Topgun 250 high temperature and high pressure cleaner is used to produce high pressure and high temperature water vapor with pressure of 250bar and temperature of 150 ℃ High temperature can make oil, oil dirt and Wax Melt rapidly, and high pressure water flow can take away these melted substances Low cost: the cleaning cost of each oil pipe is only 2-3 yuan High efficiency: the cleaning time of each oil pipe is about 2 minutes The cleaning effect is good This equipment and technology have been widely used in CNOOC, Dagang, Daqing, North China and other oilfields Beijing Zhongkai Yingchuang Petroleum Equipment Co., Ltd has been committed to the promotion of oilfield cleaning technology If you are interested, please call :
