SYSTEM OF ALTERNATE RESISTANCE TO FLOW (VERSIONS) DESIGNED FOR USE IN UNDERGROUND WELL AND SYSTEM OF WELL PRODUCTION

摘要

FIELD: oil and gas industry.SUBSTANCE: group of inventions relates to equipment of underground well operation, providing for alternate resistance to a flow of various wanted and unwanted fluid media within a fluid composition. The technical result - flow regulation device improvement. The device comprises a through chamber for the passage of the fluid composition, having an inlet and an outlet. There is a possibility provided for the fluid composition arrival into the chamber via the inlet in the direction that changes depending on the ratio between the content of the wanted fluid medium and unwanted fluid medium within the fluid composition. The device comprises at least one structure acting therefore at any part of the fluid composition passing in a curved manner between the inlet and outlet to maintain such a curved flow.EFFECT: specified structure has at least one hole making it possible for the fluid medium to pass straight from the inlet to the outlet.48 cl, 15 dwg
