Abstract

The invention discloses a water injection control valve which comprises a body. A water injection pipeline is arranged at one end of the body along the elongation direction of the body and is communicated with a pipeline B through a pipeline A, the pipeline B is perpendicular to the water injection pipeline, a pipeline C perpendicular to the pipeline B is further arranged in the body, the pipeline B is communicated with the pipeline C, two connectors II are oppositely arranged on the outer wall of the body, each connector II is positioned at one end in the body and communicated with a one-way valve, a water sump is arranged at one end of the body close to the pipeline C, the pipeline C is communicated with the water sump, and the water sump is communicated with two one-way valves. Open and close of the water injection pipeline can be conveniently controlled through a needle valve II on the water injection control valve, water injection flow can be conveniently controlled by monitoring water flow and adjusting the one-way valves by the needle valve II, and the water injection control valve solves the problems that the water injection process is inconveniently controlled and working efficiency is low in the separated layer water injection technological process.

Description

technical field [0001] The invention belongs to the technical field of hydraulic components and relates to a water injection control valve. Background technique [0002] In the development of oil and gas fields, in order to ensure the pressure of the oil and gas fields, the oil is displaced, so water or gas is injected into the formation, and the water injection channel is called a water injection well. Layered water injection separates oil layers with large differences, and then uses a water distributor to distribute water in layers, so that the water injection volume of high permeability layers is controlled, and the water injection volume of medium and low permeability oil layers is strengthened, so that all types of oil layers can play a role . In the process of underground layered water injection in existing oilfields, if it is necessary to control the start or stop of water injection, it needs to be realized by opening or closing the valves of the water injection stat...
