Abstract
The most technologically useful for assembling columns in the conditions of crafts are muffled threaded joints. However, the disorder of standard threaded connections causes 70% of all complications with casing and pump-compressor columns. This leads to significant material losses, reduced productivity of the selection of raw materials, pollution of the earth's interior and the environment. Particularly acute is the loss of tightness of these compounds in the exploration and development of gas and gas condensate fields. Pump-compressor tubes (tubes) operated in wells with a watering capacity of more than 60% and in deep-well wells with a curvature of more than 140 can not withstand the established service life. Premature failure of tuberculosis occurs due to the aggressive action of formation water, organic acids, aggressive gases, hydro-erosive effects, mechanical wear, as well as fatigue failure due to variable loads. Therefore, the actual task is to improve threaded joints in order to increase their reliability and performance for conditions of high operating loads. To solve them, it is necessary to conduct theoretical and experimental research, on the basis of which it is possible to develop effective methods and means to increase the reliability of attachment of oil and gas wells.
