Ⅰ. Overview:

The dual-acting centralizer is improved on the basis of the problems existing in the field application of oil well control bias wear. It uses carbon fiber composites, high wear resistance. The centralizer steel body has four forced commutation grooves, each stroke cycle, the carbon fiber centralizer rotates by 90 degrees, and the centralizing block rotates automatically in the well for one week to make the centralizer wear evenly. Overcome the conventional centralizer centralization block bias wear problem, prolong the use of centralization block. The dual-acting centralizer is advanced in design. The structure is reasonable. The movements are flexible. Reliable use. Easy to operate and other features, is the alternative to the control of grinding wells.

V. Scope of application:

It is suitable for the treatment of oil well partial wear within 2000m.

VI. Usage instructions:

1. Check tools:

Tools must be carefully checked before going down to make sure the tools are in good condition. The check reads as follows:

(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) track commutation mechanism should be flexible, without any blocking phenomenon.

2. The tubing under the tool must be unobstructed and must be greater than the maximum external diameter of the tool.

3. Downhole tubing and tools must be kept clean. The tubing is made up of standard tubing gauges, and the measurement of tubing dimensions is accurate.

4. The down-hole operation rules and safety regulations should be strictly carried out in the double-acting centralizer downhole. The operation should be stable and the speed should be moderate (30 / H), should not be raised sharply). Brake. Let go. The wellhead must be fitted with an indicator.

Seven。 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.

2. The used tools are delivered to the original shipping unit for maintenance to ensure its performance.

3. This product should be transported and stored to avoid collision and rain, both ends of the buckle with wire protection.

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.
