Embodiment

[0027] Such as Figure 1~3 As shown, a water distributor adjustment structure includes a fairing 1, a main body 2, a compression spring 3, a moving piece 4, a fixed cylinder 5, a driving sleeve 6, a motor assembly 7 and a water guide pipe 10. The fairing 1 is connected to the front end of the main body 2 through bolts, and the fairing 1 is located at the entrance of the internal channel of the main body 2 . The opening at the end of the fairing 1 is a conical water-passing grille, and the rear barrel-shaped structure rectifies the water flow entering the internal channel.

[0028] The interior of the main body 2 has internal passages for the circulation of water injection. The fixed cylinder 5 is fixed in the internal passage of the main body 2, and the fixed cylinder 5 is provided with layered channels, through which the water flow entering the internal channel is diverted in layers, and the layered channels can be provided with one layer, two layers or more layer. The int...

Abstract

The invention discloses a water distributor adjusting structure. The water distributor adjusting structure comprises a main body with an internal channel, a fixing cylinder is arranged inside the internal channel of the main body, a layering channel is arranged on the fixing cylinder, a rotating movable piece is arranged in the internal channel of the main body, a movable piece matches at an inlet of the layering channel, and a water outlet opposite to the layering channel is formed in the main body. The water distributor adjusting structure has the advantages and beneficial effects that water injection of two stratums is achieved through one set of control system, the functionality of the water distributor is improved, rotation angle control is achieved, accurate layering can be achieved, the flow injected into a single layer or two layers is controlled, layered water injection is achieved through the layering channel, a water passing channel is omitted, the overall structural size is reduced, the size is small, and work is efficient.

Description

technical field [0001] The invention relates to an oil field water injection instrument, in particular to an adjusting structure of a water distributor. Background technique [0002] Layered water injection means that a packer is lowered into the water injection well to separate the oil layers with large differences, and then the water distribution device is used to distribute water in layers, so that the water injection volume of the high permeability layer can be controlled, and the water injection of the middle and low permeability oil layers can be obtained. Enhanced, a water injection method that enables all types of oil layers to play a role. At present, in the development process of oilfield water injection instruments and tools, water injection instruments have complex structures, large volumes, and limited functions, which cannot meet the increasing demand for water injection. Therefore, the existing field has begun to develop intelligently and multi-functionally. ...
