COMBINED DEVICE FOR CLEANING THE INTERNAL SURFACE OF COLUMNS OF PIPES IN A WELL OF DEPOSITS (OPTIONS)

摘要

The proposal relates to the field of oil and can be used in oil producing wells during their operation. The technical result is expressed in the realization purpose utility model and decrease the time required to descent device downhole. For this purpose the device comprises a housing having a detachable connection at the top to allow connection to a connecting element for connection with a traction organ. On the shaft connected with its upper part through the load, or directly to the housing is mounted freely rotatably, at least one cleaning head with obliquely arranged relative to the longitudinal axis of the cutting elements. There is an additional cleaning unit disposed on the housing. The housing is designed as a carrier plate stabilizer, additional purification unit - in the form of spaced adjustment of arcuate blades. The lower knife is fixedly mounted on the housing, and the upper - plane-movably with the possibility of limited movement. A distinctive feature of the second embodiment is the presence of at least one cleaning head with obliquely arranged relative to the longitudinal axis of the cutting elements having a shape close to spherical, such as an ellipsoid. 2 bp f-ly, 11 ZP f-ly. 3 yl.
