DEVICE FOR PROVIDING GEOSTATIONARY OF NAVIGATIONAL EQUIPMENT OF TELEMETRIC SYSTEM OF MONITORING OF WELL DIRECTION

摘要

FIELD: mining.;SUBSTANCE: geostationary device for navigational equipment of the telemetry tracking system of the wellbore trajectory includes a hollow cylindrical hermetic body comprising a base rotatable. Based on the installed navigation sensors. A speed sensor, a torque motor is installed in the housing, a cylindrical hole is made in the stator of the instantaneous motor, into which the current conductor and the first bushing connected to the base are mounted. On both sides of the body, there are two shock absorbers with gaskets. The first shock absorber is fixed to the torque motor on one side, and on the other hand, it is made with the possibility of a rigid connection, for example, with the telemetry system equipment. The second sleeve contains a rotation bearing, is rigidly connected to the second shock absorber and is connected to the base via a rotation bearing. The second shock absorber is designed to be rigidly connected, for example, to the power part of the bottom hole assembly. The stiffness of shock absorbers in the transverse direction exceeds the longitudinal one.;EFFECT: increasing the reliability of the device, increasing the stability of the geostationary position of navigation sensors, increasing the accuracy of determining the spatial position of the drilling tool.;1 dwg
