RU28174U1 - DEVICE FOR CLEANING INTERNAL CAVITY OF PIPES FROM PARAFFIN AND OTHER DEPOSITS - Google Patents

Description

A device for cleaning vyutrenny cavities of pipes from paraffin and other deposits

The utility model relates to the oil and gas industry, in particular, to devices for cleaning tubing from paraffin and other deposits.

A device for cleaning internal pipe cavities from paraffin and other deposits is known, the known device comprises a housing, a cleaning head with cutting edges, made integral with the impeller mounted on the shaft for rotation, an attachment unit to the traction body, mounted in the upper part of the housing and stabilizer, and the stabilizer is made in the form of longitudinal protrusions located on the housing, each of which has a sharp edge at the apex and two lead-in sections at the ends of the protrusion, in the treatment head a mechanism is fixed that ensures unimpeded rotation of the treatment head in one direction only, and a bearing is mounted between the housing and the attachment unit to the traction unit. (Witnesses of the Russian Federation No. 11261, Е21 В 37/02, publ. 16.09.95, bull. No. 9).

In the known device, when refueling into the well and lifting, the traction body experiences large bending stresses.

The objective of the utility model is to increase the reliability of the device.

The technical result achieved by the implementation of the claimed device is to reduce bending stresses in the traction body.

The problem with the achievement of the technical result is solved in that the device for cleaning the internal cavities of the pipes from

paraffin and other deposits contains cleaning heads with cutting 1 crowns, an attachment unit to the traction unit and a load, according to a utility model, an attachment unit to the traction unit further comprises a shock absorber in the form of a coil spring, inside of which a traction unit is passed.

The figure 1 shows the proposed device.

The device consists of a load 1, cleaning heads 2 with cutting edges 3, a connection unit 4 to the traction body - a wire 5. The connection unit 4 contains a shock absorber 6. The shock absorber can be made, for example, from a coil spring.

The device operates as follows. With the buffer valve closed, the device is placed in a lubricator. Lubricator is sealed. Open the buffer valve and through the traction of the wire 5 carry out the descent of the device into the pipe string. The shock absorber 6 prevents the bending and twisting of the wire 5. The sharp edge of the treatment head 2 cuts into tight deposits and forms a grid of spiral grooves in them. The cleaning head rotates only due to the interaction of cutting pans 3 and deposits.

When moving the traction body - wire 5 up, the cutting edge 3 cuts off the remnants of dense deposits. The flow passing through the grooves between the sharp 1shapes 3, cuts off the cut products.

By lowering and raising the device to the required depth, they produce an inner surface of the pipes.

This embodiment of the device allows you to reliably operate it at a high density deposits.
