Oil drain rotary ZX

I. Summary:

The rotary oil discharge device is improved on the basis of the problems existing in the field use of the oil well venting device at present. It is aimed at the oil rod break that often occurs in the process of oil well operation, the release or piston dropping can not open the oil venting device and the sand buried pump barrel, the heavy oil, the conventional pin oil discharge device in waxing well can not realize the oil discharge and the spurting operation is carried out. Causes the energy waste environment pollution and increases the work difficulty and so on the question specially designed. The oil venting device is advanced in design. The structure is reasonable. The movements are flexible. Reliable use. Easy to operate and other features, is a substitute for oil well spillers.

II. Structural characteristics:

The assembly diagram is as follows:

The main components: upper, lower joint, central pipe, upper and lower release sleeve, oil drainage anchoring device and so on.

V. Scope of application:

Suitable for oil wells within 2500m.

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) Kava shall be free to move without any blocking phenomenon.

(5) the kava and the climbing body must be waxed tightly.

2. The well under the tool must be sand-washed to the bottom of the artificial well: it must be open to the well to ensure that it is not obstructed and the out-of-gauge passage of the well 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, accurate measurement of tubing dimensions, thread coating and fastening of oil to ensure that 20MPA does not leak.

4. The operation rules and safety regulations should be strictly implemented in the downhole of rotary oil spillers. The operation should be stable and the speed should be moderate (30 / H), should not be raised sharply) in the process of downhole. Brake. Let go. The wellhead must be fitted with an indicator.

5. When down the tubing, the back clamp must be made to prevent the string from turning and avoid the mid-way oil leakage.

6. The rotary venting device is connected to 1 or 2 tubing above the pump, and the lower joint is fastened to the tubing without leakage.

7. Rotary oil spillers cannot be used with Packers (or assemblies) sealed by rotary seats.

8. When the pipe lifting operation is carried out in the construction well of the rotary oil drain, when the liquid surface is seen in the upward lift tubing, the suspension tubing, with hydraulic tubing pliers, turns the fast gear several times, and after opening the anchoring device of the oil drain device, it is then changed to a slow-speed positive rotation of about 20 turns. Check the liquid level, such as descent, indicating that the drain switch has been turned on, can normally lift the tubing, otherwise continue to spin the tubing until the switch is open. The 10 cm string should be properly lowered slowly during the operation of the rotary oil drain.

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.

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.
