COGENERATION SYSTEM OF ENERGY SUPPLY OF CLUSTER DRILLING RIG Russian patent published in 2018 - IPC E21B41/00 

FIELD: power engineering.

SUBSTANCE: invention relates to heat and power engineering, namely to cogeneration systems for obtaining energy for power supply of machines and complexes of oil production facilities with the use of associated petroleum gas as an energy carrier and heat to ensure the own needs of enterprises of the mineral and raw materials complex, located far from the existing centralized power supply systems without communication with the unified energy system. Cogeneration power supply system of the cluster drilling rig contains an electrical equipment unit and a unit with capacitive equipment. At the same time, the electrical equipment unit is made in the form of a micro-gas turbine electric generator, connected by a pipeline of the exhaust system with a plate heat exchanger and a coil located in the tanks with the drilling fluid of the capacitor equipment block. Moreover, the plate heat exchanger is connected by an additional pipeline with the air heating system of the derrick building.

EFFECT: technical result is increased overall energy efficiency of drilling operations, improved working conditions of the drilling crew, and provided technology for the preparation and storage of drilling fluid.
