Document Type and Number:
WIPO Patent Application WO/2023/121512
Kind Code:
A1
Abstract:
The group of inventions relates to the oil production industry, and more particularly to downhole equipment, and even more particularly to downhole electric valves for carrying out killing, completion, flushing and hydraulic fracturing operations on a producing formation and subsequently controlling and adjusting inflow (injection) to increase oil or gas recovery. The present electric valve is intended for installation in a well as part of the well tubing. The valve is designed to be capable of controlling the flow of fluid between the tube side and the annulus side at the point where the valve is located and comprises a hollow cylindrical housing with ports, a sleeve arranged inside said housing and having ports, said sleeve being capable of moving between an open position and a closed position in response to a signal received over a remote communication link, and an electric motor connected to the sleeve, wherein the housing is designed to be capable of acting as the stator of the electric motor, and a hollow valve of the electric motor rotor and the movable sleeve are directly connected or are connected into a single rotatable structural element. The invention makes it possible to expand the operational and functional capabilities of a downhole valve while simultaneously increasing the reliability thereof.
