DRILLING RIG, SYSTEM AND ITS MOVEMENT METHOD Russian patent published in 2023 - IPC E21B7/02 

FIELD: drilling.

SUBSTANCE: group of inventions relates to the movement of a drilling rig at a deposit, without assembly and disassembly of structural components. A system for movement of a drilling rig moves the drilling rig or similar structure at an oil deposit or in similar conditions and includes independently controlled installation shoes attached to the drilling rig and controlled with individual and coordinated position control commands. Each of a set of independently controlled installation shoes can change a position of the drilling rig. Each of independently controlled installation shoes includes a case attached to the drilling rig and a structural shell for accommodation of a hydraulic drive and a wireless control circuit. The hydraulic drive provides vertical, horizontal, and rotary forces in response to wireless control signals from the wireless control system. The wireless control system transmits wireless data on a position, control and commands by means of a remote wireless communication device and converts wireless data on a position, control and commands into signals for control of the hydraulic drive. A pusher of an installation shoe cylinder vertically lifts the hydraulic drive, receives and transmits vertical and rotary forces from the hydraulic drive. A node of an installation shoe support is rigidly connected to the pusher of the installation shoe cylinder, receives and transmits a horizontal force from the hydraulic drive. The pusher of the installation shoe cylinder and a transverse movement cylinder of the installation shoe provide stepless adjustment of a position of the independently controlled installation shoe.

EFFECT: reliable, fast, and simple control of placement and position of a drilling rig.
