SYSTEM OF DRILLING RIG WITH SELF-LIFTING DRILL FLOOR Russian patent published in 2016 - IPC E21B15/00 

FIELD: mining.

SUBSTANCE: group of inventions relates to a drilling rig system and a method of assembling the drilling rig. Transportable drilling rig with a self-lifting drill floor includes a base structure containing several base supports of a tower type, which can be transported to the drilling site and installed around a well shaft drilling point. Horizontal base frame is installed between the lower parts of the tower supports for formation of a stable base structure of the drilling rig, and the drill floor can then be mounted on the base frame between the base supports of tower type. Suitable derrick of the drilling rig can then be mounted on the drill floor. Floor lifting wire ropes are attached to the upper parts of the tower-type supports and reeved into corresponding pulley units connected to the drill floor. Free ends of wire ropes for floor lifting can be attached to a casing block in the drilling rig derrick, after which a drill winch of the rig can be actuated for lifting of the drill floor and derrick into a required position with subsequent attachment to base supports of tower type.

EFFECT: higher efficiency of assembly/disassembly of a drilling rig.
