DRILLING RIG WITH HIGH RATE OF ROUND-TRIP OPERATIONS Russian patent published in 2020 - IPC E21B19/08 E21B19/20 

FIELD: drilling of wells.

SUBSTANCE: group of inventions relates to drilling rigs and methods of moving tubular candles. Drilling installation includes: upper drive assembly, made with possibility of vertical translational movement along tower; rack module connected to the tower; pipe supply lever made with possibility of vertical translation along the tower. Pipe feed lever comprises a pipe clamp which is configured to move between a position in the well center above the well center and a second position, located ahead of position in the well center. Drilling rig also comprises: an upper drive bogie connected with the tower translationally; tackle assembly; upper drive, suspended on tackle assembly in assembly; cross bar connecting traveling block with bogie of upper drive with possibility of rotation; extending drive connected between upper drive car and crossarm; propeller shaft, rigidly connected with tackle unit. Propeller shaft is connected with possibility of vertical sliding movement with upper drive. As a result of the drive extension, the crossarm is turned to extend the tackle block and the top drive from the bogie for placement above the well center. As a result of the drive retraction, the beam is rotated to drive the tackle block to the bogie for placement away from the well center.

EFFECT: technical result consists in acceleration of lifting and lifting operations.
