<p>The invention relates to the oil industry and can be used for putting into operation paraffined oil wells in different climatic regions. The inventive method differs form the known methods in that it consists in simultaneously controllably heating different layers of a heating cable wound on a drum when said heating cable runs in the well, in overcoming a high well head pressure acting on the cable by a transporter axial force which ensures the alignment of the lowered cable with the pushing well head pressure and in running the hot cable in a paraffin-forming area by gravity. The inventive device for putting into operation a paraffined oil well comprises a heating cable (hereafter a cable) whose one end is connected to a power supply and the other end is closed an insulated inside the cable which is provided with at least one temperature sensor arranged therein. According to said invention, the cable, prior to be lowered, is wound on a controllable winch drum and temperature sensors connected to respective temperature measuring devices are disposed between the cable winding layers. The invention for putting into operation a paraffined oil well is characterised in that it also comprises a one-drive cable transporter which is used for running in and lifting the cable in the wellhead area under a high well head pressure and comprises a detachable body consisting of two parts one of which is embodied in the form of a power-driven part and the other in the form of a cover. Each body part comprises independent rolls which are arranged therein on whose axes gear wheels are rigidly fixed and disposed in such a way that they are cinematically connected to each other and to rolls. Odd number of pairs are mounted on the power driven part of the body, the shaft of one pair is connected to a drive, the cover shafts are disposed just on center between the shafts of the power-driven part of the body, wherein the gear wheels thereof are connected by pairs to each gear wheel of the cover.</p> |
