Description

Floating scraper type high pressure water jet nozzle

technical field

The utility model relates to the technical field of oil pipe cleaning devices, which is a floating scraper type high-pressure water jet nozzle.

Background technique

At present, there are more than 4,000 oil and water wells in Karamay Oilfield, about 1 million oil pipes in use, and 230,000 to 300,000 meters of oil pipes need to be cleaned every year; if the cleaning efficiency and effect of conventional nozzles can be improved, energy consumption and cost-effectiveness can be reduced quite a lot. Conventional nozzles have cleaning blind spots when cleaning the inner wall of the oil pipe, and it is difficult to clean stubborn dirt under a certain working pressure. The accumulation of oil dirt in the tubing will affect the normal production of the oil well, and more serious may lead to blockage of the tubing. If the oil pipe is not cleaned and used again, it is easy to cause the accumulation of dirt. At this stage, if the cleaning effect is to be improved, the working pressure will generally be increased. However, the higher the working pressure, the higher the performance of the equipment and the tightness and material requirements of the high-pressure jet system will also increase, which will increase the cost of oil pipe cleaning and the danger of high-pressure work.

Below in conjunction with embodiment and accompanying drawing, the utility model is further described:

As shown in Figures 1 and 2, the floating scraper type high-pressure water jet nozzle includes a nozzle body 1, a high-pressure jet nozzle, a nozzle cap 2 and a floating scraper 3; There is at least one through hole 5 communicating with the water inlet channel 4 in the middle part, and a high-pressure jet nozzle is fixedly installed on the outer inner wall of the radial through hole 3, and at least two scraper grooves 6 are distributed along the circumference of the nozzle cap 2, and the scraper There is a compression spring 7 at the bottom of the groove 6. The floating scraper 3 is fixedly mounted on the compression spring 7 and is located outside the nozzle cap 2. The outer ring surface of the nozzle cap 2 is higher than the outer ring surface of the high-pressure jet nozzle. When in use, when cleaning the inner wall of the oil pipe, the oil pipe can be rotated in and out. The inner wall of the oil pipe is first cleaned by a high-pressure jet, and then mechanically cleaned by the elastic floating scraper 3. The elastic floating scraper 3 can closely fit the inner wall of the oil pipe to achieve the best cleaning effect. There are cleaning "blind areas" and residual dirt, and the stubborn dirt can be effectively removed without increasing the working pressure. The nozzle cap 2 can effectively prevent the oil pipe from vibrating and abrading the high-pressure jet nozzle, and protects the high-pressure jet nozzle.

According to actual needs, the above-mentioned floating scraper type high-pressure water jet nozzle can be further optimized or/and improved:

The high-pressure jet nozzles are distributed on three sides of the nozzle body 1 in a three-dimensional spiral shape. During cleaning, the jet cleaning beams of the high-pressure jet nozzles interfere with each other to form a flushing overflow area on the inner wall of the oil pipe. Here, the flushing overflow area is defined as a water belt, and the water The width and length of the belt increase with the increase of the working pressure. The cleaning area of the hose can be adjusted by the pump pressure. When the coverage area of the hose is large enough, the cleaning blind area on the inner wall of the pipeline can be eliminated; the V-shaped groove 8 There are through holes perpendicular to the side wall. When installing and using, ensure that the installation angle of the high-pressure jet nozzle is 45°, which can not only ensure sufficient radial impact force, but also have sufficient axial impact force.
