| Summary: | An analysis of the main loads acting on drill string pipes in the process of drilling an oil well is performed. The method is given for determining the total bending stresses arising in the drill string pipes, depending on the geometric parameters of the well, as well as taking into account the drill string operation, depending on the drilling equipment basic parameters (bit load and rotor speed). The calculation is made for the bending stress components caused by the well curvature, as well as the column stability parameters as a flat rod determined by the rotor speed and the bit load. An analysis of the influence of changing drilling parameters on the total amount of bending stress is carried out for various options of the drilling equipment operation. The dependences of the maximum bending stresses on the increased values of the bit load and the rotor speed are obtained. Conclusions are made on the influence of the main operating parameters of the drilling equipment on the magnitude of the bending stress experienced by the drill string pipes during the oil well drilling. |
