CLUSTER DRILLER Russian patent published in 2018 - IPC E21B15/00 E21B7/02 E04H12/18 

FIELD: soil or rock drilling.

SUBSTANCE: invention relates to cluster drillers for production and exploration drilling of oil and gas wells. Cluster driller includes a towing unit with a winch, a rotor, a drilling wrench, modules for rough cleaning, fine cleaning and storage tanks for drilling mud, a module for collecting sludge from a circulating system, modules for a pumping unit connected to each other and a derrick-winch block and located in a level on supports. Modules for mud pumps, coarse drilling mud and sludge collection are installed longitudinally on two trolleys, interconnected with derrick-winch block, and the energy modules are installed behind the derrick-winch block. Remaining modules of the circulation system are installed transversely on supports, while the fine cleaning unit and one drilling mud storage capacity, combined into a single module, are located respectively behind the modules of rough cleaning, collecting sludge and mud pumps. Modules for mud pumps, rough cleaning and sludge collection mounted on trolleys are provided with lower and upper cross beams, while the beams of adjacent modules are rigidly interconnected, and the lower cross beams are rigidly connected with trolleys.

EFFECT: technical result is reduced complexity of manufacturing and installation.
