The formation of solid deposits of paraffin contained in oil on the inner surface of tubing is one of the adverse factors that significantly complicate the operation of oil wells. Existing methods of cleaning of pipes from paraffin deposits are considered. The scheme and design of the hydro-mechanical device used for cleaning inner surfaces of tubing from paraffin deposits have been developed. Laboratory and practical tests of the developed device are conducted. According to the test results, we can say that hydro-mechanical methods of purification from paraffin deposits are the one of most effective. Setting of drive allows to promote automation of cleaning of tubing, that is provided by absence of necessity of creation of axleloading on stem - from action of expense and pressure of liquid a device independently moves in the cavity of tubing. Also it should be noted that a drive promotes efficiency of process of destruction of paraffin due to creation of oscillation influence. Experimental laboratory researches of drive of cleansing device proved his capacity at the expense of liquid from 0,15 to 0,63 l/s. At the indicated range of expense of liquid the drive of cleansing device provides his steady vibromoving. It is set that high speed of vibromoving of cleansing device is arrived at the expense of liquid from 0,55 to 0,63 l/s. During realization of commercial tests of an experience construction of hydro-mechanical device a cleaning process took place in the automatic mode at the observance of the same values of parameters of temperature and pressure of festering of the heated water in cleansing device, that were set for standard technology of cleaning of tubing in oil and gas mining companies. The conducted laboratory and experimental experiments of the worked out device allow to recommend it for the use in field practice.
