SYSTEM AND METHOD OF USING THE INTEGRATED COLLECTOR OF PRESSURE EXCHANGE FOR HYDRAULIC FRACTURING OF FORMATION Russian patent published in 2018 - IPC E21B43/267 F04F13/00 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to variants of a system and a method for treating a fluid for fracturing a formation. System is proposed that includes an integrated collector system containing several isobaric pressure exchangers (IPX), each having an inlet for the first fluid at a low pressure, an inlet for the second fluid under high pressure, an outlet for the first fluid under high pressure, and an outlet for the second fluid at a low pressure. Integrated collection system includes a reservoir for the first low pressure fluid that is connected to each of the inlet ports for the first fluid at a low pressure and configured to supply the first fluid at low pressure to each of the inlet ports for the first fluid under low pressure; a header for a second fluid under high pressure connected to each of the inlet ports for the second fluid under high pressure and configured to supply the second fluid under high pressure to each of the inlet ports for the second fluid under high pressure; a header for a first fluid under high pressure connected to each of the outlets for the first fluid under high pressure and configured to discharge the first fluid under high pressure; and a header for the second low pressure fluid connected to each of the outlets for the second fluid under low pressure and configured to discharge the second fluid under low pressure.

EFFECT: technical result is to increase the efficiency of hydraulic fracturing of formation.
