INSTALLATION FOR DRILLING, TESTING AND REPAIR OF OIL AND GAS WELLS UPA-80 Russian patent published in 2009 - IPC E21B7/02 

FIELD: oil and gas production.

SUBSTANCE: invention refers to drilling equipment. The technical result is achieved due to a known installation consisting of a self-propelled transport vehicle and of a frame with equipment assembled thereon; according to the invention a winch of the installation is made single-drum with a chain drive, while a distributing reduction gear is made conical - one-stepped; also the front and rear support of the mast are rigidly mounted on the frame; two brackets and a crow's nest equipped with a facility for evacuation of a derrick man are arranged on the upper section of the mast; notably, a repair platform is hinged on the rear support of the mast and is designed to be transformed from a working position into a transport one; a block-and-tackle system is equipped with a traveling block. The disclosed installation is of a simplified design in comparison with the prototype model due to implementation of the single-drum winch, a block-and-tackle system of simple design, demountable structures of the crow's nest and the repair platform.

EFFECT: reduced cost of structure of installation due to simplification and to reduced metal consumption at maintaining functionality to perform operations at completion and repair of oil and gas wells.
