one, Â Â Â Â Â Â Â Â Â Foreword
Ensure the quality of oil well operations, extend the inspection cycle, reduce the rework of operations, and reduce operating costs. Cleaning as the first process in the tubing repair test line,
It can effectively remove the oil, wax and scale inside and outside the tubing rod, ensure the cleanliness of the repair tubing rod, and create clean conditions for other processes.
   Tubing cleaning mainly consists of high-pressure water jet and hot boiling. In winter, due to the large number of oil pipes recovered from the well, and the wax layer is thick and hard, it is generally boiled by hot water, and the other seasons are cleaned with high-pressure water jet.
In addition, the tubing has often caused the entire well tubing to be scrapped due to fouling of the inner wall. The high-pressure water jet cleaning process is used to clean the inner wall of the oil pipe, and the fouling effect is obvious, which can effectively reduce the waste of the oil pipe.
two, Â Â Â Â Â Â Â Â Â High pressure water cleaning
       1. Equipment selection:
Italy Aoweks Group "Aowei Alex" high temperature pressure washers, hot water pressure washer TOPGUN250 (the device by the exclusive agent in Beijing Kay surplus Petroleum Equipment Co., Ltd.)
2, high temperature and high pressure cleaning machine, hot water high pressure cleaning machine technical parameters :
Pressure: 30 ~ 250bar
temperature:
flow:
Power: 11KW
3 , TOPGUN250 high temperature and high pressure cleaning machine , hot water high pressure cleaning machine principle and characteristics
   TOPGUN250 high-temperature high-pressure cleaning machine , hot water high-pressure cleaning machine cleaning principle is to use high-pressure pump to pump high-pressure water, heated by heating coil to 150 ° high temperature hot water steam , through the pipe to the nozzle,
The nozzle converts the high-pressure low-flow water into a low-pressure high-flow jet, which impacts the surface of the cleaning member in a forward or tangential direction; the high-temperature hot water vapor rapidly dissolves the oil and grease on the surface of the object. Jet in
Sufficient pressure is generated on the scale layer or deposit to cause pulverization. Once the scale layer is penetrated, the fluid is wedge-shaped between the scale layer and the surface of the cleaning member, so that the scale layer falls off to expose the surface of the surface to be cleaned.
The layered or porous scale is liable to be broken because the impact of the jet can hit a hole and an internal pressure is formed below the surface of the scale to cause the upper scale to crack. In many jet operations,
The inclusion of crushed particles in the jet can help to impact more particles.
   4 , TOPGUN250 high temperature and high pressure cleaner, hot water pressure washer structure
   TOPGUN250 high temperature and high pressure cleaner, hot water high pressure cleaner mainly consists of high pressure piston pump, power part, heating part, nozzle, high pressure hose
And work attachments and other components.
   ( 1 ) . High pressure piston pump
   The high pressure piston pump is the main component of the Zui in the high pressure water jet cleaning device. The choice of ceramics is both resistant to high temperatures and wear, which increases the service life of the high pressure pump.
   ( 2 ) . Power part
The power source is an 11 kW electric motor. Using 380 volt 50 Hertz power supply plants, very easy to use. This motor is 1000 r / min speed motor, to effectively reduce the high pressure piston pump
Wear and tear. Continuous working hours can reach more than 10 hours.
( 3 ) . Heating section
The heating part is a double-layer heating hob coiled by a seamless steel pipe of more than 50 meters of stainless steel. It can make the cold water fully heated, and the thermal efficiency is over 95% .
Thereby achieving
   ( 4 ) . High pressure hose
   Pass between high pressure water pump and nozzle
Strength to withstand high pressure, while the outer skin protects against corrosion and mechanical damage. The high-pressure hose and the reinforcing layer are woven with steel wire, generally having 2 to 3 layers.
   ( 5 ) . Spray gun, nozzle and work attachment
The high-pressure water passes through the hose and reaches the spray gun, nozzle and working accessories. The nozzle converts high pressure, low flow rate water into a low pressure, high flow rate jet. Under certain other conditions,
The cleaning effect depends mainly on the accessories and nozzles of the high pressure cleaning device. Generally, the nozzles are made of a variety of special metals. In order to produce a water jet for cleaning, generally
Both cylindrical and flat nozzles are used. Because the structures of the two nozzles are different, the effect is different. The jet of the cylindrical nozzle has a long range, but the action area is small;
The jet of the flat nozzle has a shorter range but a larger area of ​​action.
three, Â Â Â Â Â Â Â Â Â Â Â Â Â Â Tubing cleaning process
1, Â Â Â Â Â Â Â Â Â Â Â Â Cleaning of the outer wall of the tubing:
2, Â Â Â Â Â Â Â Â Â Â Â Â Cleaning of the inner wall of the tubing:
The inner and outer walls of the tubing are covered with oil, grease, and wax, which are generally difficult to clean. The old process generally uses the method of caustic soda, the speed is very slow, the cost is high, the efficiency is low, and the cleanliness is poor.
The use of high-temperature high pressure cleaner TOPGUN250 a pressure 250bar, temperature
The high-pressure water stream can take these melts away. Low cost: the cleaning cost of each tubing is only 2 to 3 yuan. High efficiency: the cleaning time of each tubing is about 2 minutes
. The cleaning effect is good.
