Abstract

The article deals with the results of field testings of the automatic winding machine for ECP cable in the process of down-lifting operations in the underground and overhaul repair of oil wells at the fields of Joint-Stock Oil Company Bashneft. During the overhaul or underground repair of oil wells equipped with ECP centrifugal pump installations, the mounting of the KRBK cable to the tubing body with special clamps is added to the technological process. This process requires stopping the process of lowering the tubing string. Thus, in the process of lowering the tubing string into the well, a synchronous operation of the mechanisms is necessary: cable feed (KRBK automatic winding maschine) and the mechanism of movement of NK pipes. Taking into account the requirements of safety and porvision of integrity and serviceability of the KRBK cable in the process of down-lifting operations in the underground and overhaul repair of oil wells, smooth stopping and starting of automatic winding maschine is necessery, as well as the synchronous operation of the KRBK automatic winding maschine and the system of lifting and lowering the column of the tubing. Abrupt stopping and starting of the work of automatic winding maschine leads to tension and overvoltage of the cable, which is unacceptable and can lead to destruction of the cable as a whole (breakage, violation of insulation, integrity). For starting and stopping the cable drum (7-8 tons) the following is necessary: a sufficiently large power of the electric motor; gearbox. Moreover, the moment of inertia of the untwisted cable drum is long enough, which is the cause of failure of the gearbox, electric motor and belt drive. Considering the above said, the article proposes the kinematics of the automatic winding machine, which has passed field testings and allows smooth, synchronous operation being done, aas well as eliminating damage of the KRBK cable and optimizing the expenses of maintenance and repair of the automatic winding machine.
