POWER UNIT OF PUMPING UNIT FOR DEEP-PENETRATING HYDRAULIC FRACTURING OF BRIDGES IN ISOLATED CAVITIES OF OIL AND GAS FORMATIONS Russian patent published in 2024 - IPC F04B47/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to units for hydraulic fracturing of oil and gas formations and can be used for the most complete development of isolated cavities during drilling of oil and gas fields. The power plant of the pumping unit for deep-penetrating hydraulic fracturing of bridges in isolated cavities of oil and gas formations comprises an internal combustion engine with an effective power of 3000 to 6000 hp, a two-flow multi-speed high-speed gearbox, the intermediate shafts of which are mounted on the outer gears of a spur transfer gearbox and are connected to the internal combustion engine through a speed-raising planetary gearbox with a fixed epicyclic gear with a gear ratio i₁ = 0.25, and the load shaft is connected to a cylindrical-planetary reduction gearbox of the hydraulic pump through a speed-reducing planetary gearbox with a fixed epicyclic gear.

EFFECT: increased productivity, reliability and durability of the power unit of the pumping unit, ensuring its efficient use.
