Problems solved by technology

[0003] The invention provides a split-type intelligent water distributor for large-flow water injection in oil fields, which adopts a water flow ring groove flow channel with split water inlet holes, and an electric-driven adjustable water nozzle structure that can automatically adjust the injection amount of the formation, which solves the problem of existing problems. When injecting water at a large flow rate in oilfield water injection wells in the technology, the intelligent water distributor cannot meet the problem of water injection volume, which ensures the requirements of large flow rate, reliability, and high-precision testing of water injection during oilfield construction operations

Embodiment

[0024] Such as Figure 1-3 As shown, the present invention is a shunt-type intelligent water distributor for large-flow water injection in oil fields, which includes a main body 4, which is the main body. 3 are installed in sequence, the motor 1, the limit device 2, and the water nozzle 3 are assembled and installed in the installation hole of the main body 4, and the motor 1 drives the valve core of the water nozzle 3 to move through the limit device 2 to adjust the injection volume. A water flow ring channel 13 is opened on the main body 4, and a plurality of sub-inlet water flow channels 17 are opened on the water flow ring channel 13 to ensure the entry of a large flow.

[0025] The water flow ring groove channel 13 is an annular groove opened on the main body 4, and a plurality of sub-water inlet holes 12 (corresponding to a plurality of sub-water inlet channels 17) are opened at the bottom of the annular groove, and an electromagnetic flow channel is connected to the sid...

Abstract

The invention discloses a shunting type intelligent water distributor for large flow water injection of oil fields. The shunting type intelligent water distributor includes a main body, a motor, a limiting device, an adjustable water nozzle and an electromagnetic flow meter body; the motor, the limiting device and the water nozzle are mounted on mounting holes of the main body, and a water flow ring groove channel with dividing water inlet holes are formed in the main body; a water inlet of the water nozzle communicates with the water flow ring groove channel with the dividing water inlet holes, and an electromagnetic flow meter is installed on a main water inlet hole previously formed in the main body; and injected liquid flow enters the water nozzle through a main water inlet and a plurality of dividing water inlet holes, and enters stratum from an water outlet hole on the main body to achieve the large flow water injection and the flow regulation.

Description

technical field [0001] The invention relates to the technical field of oilfield exploitation, in particular to a split-type intelligent water distributor for large-flow water injection in oilfields. Background technique [0002] Traditional intelligent water distributors generally have a small injection volume during water injection, and the small flow channel will generate high flow resistance and pressure difference, which limits the single-layer injection volume and test accuracy. For example, in offshore oil fields and difficult oil wells, water injection A single operation takes a long time, is difficult and expensive, and requires high water injection. Not only does it require high water injection volume, but it also requires high reliability and precision. Due to the small flow channel of traditional intelligent water distributors, it is difficult to meet the water injection volume required for construction operations. Not to mention the accuracy of water injection. A...
