I. Overview:

The downhole filter of water injection well is improved on the basis of the problems existing in the field application of water filtration in water well at present. At present, the water used for water injection in oilfield injection wells is mostly reinjected with oil-water separated sewage, the water quality is poor, the corrosion and perforation of water injection pipeline is accelerated, and the rust in the water injection pipeline and the surface sand and stone after the perforation are brought into the water injection well. Plug water injection tools and water injection zones. The new type of downhole filter completely solves the problem that the surface sand and stone enter the water injection well after rust and perforation, blocking the tool and water injection layer. The downhole filter design of the water injection well is advanced. The structure is reasonable. The movements are flexible. Reliable use. Features such as ease of operation, It is an alternative to the downhole filter.

II. Structural characteristics:

The assembly diagram is as follows:

Main components: upper joint, screen pipe, tubing segment, plug head, lower joint, hook, etc.

III. Physical photographs:

IV.Technical parameters:

Total length: 1920mm rigid body maximum outer diameter: Φ 110mm maximum flow: 100m3/h

Filter slot area: 452cm filter slot width: 1.5mm

V. Scope of application:

Suitable for all water injection wells.

1. Check tools:

(1) whether the two ends of the connection thread are intact or not.

(2) there shall be no permanent deformation on the outer surface of the tool after collision.

(3) all anti-release pins shall be tightened and shall not be exposed to the surface of the matrix.

(4) the center tube of the filter is free to enter and exit.

3. The inner diameter of the test gate and the production gate used in the wellhead must meet the 250 gate standard, that is, the maximum diameter should not be less than 64 mm.

4. In the first month of use, it must be put forward to check the contact tube, clean up, and then determine the subsequent cleaning cycle through the debris filtered by the pipe.

5. There is no need to bring up the connecting tube when washing the well.

Ⅶ. Transport and maintenance consideration

1. Tools out of the factory for the whole factory, use units must not be disassembled, lest after assembly can not reach the original technical performance.

4. This product shall be placed on the shelf and shall not overlap. The sun is in the sun. Rain, do not touch acid. Alkali. Salt and other corrosive substances, tools require more than 1 meter away from the heat source.
