The anti-eccentric wear coupling (pipe anti-eccentric wear device) is a supporting tool for sucker rod anti-eccentric wear of pumping wells. It has the characteristics of simple structure, convenient use, long service life and relatively low cost. It is suitable for eccentrically worn pumping wells, especially suitable for eccentrically worn pumping wells and directional inclined wells above the neutral point of the sucker rod. The sucker rod is below the neutral point and matched with the nylon centralizer on the sucker rod body for better anti-eccentric wear effect.
The sucker rod guide, also known as the universal coupling, is suitable for directional wells, horizontal wells, and well conditions with large doglegs. It is used in series with the sucker rod and is arranged at a fixed point at the deflection point. The sucker rod can be placed underneath. To the horizontal segment. Mainly play a guiding role in the pipe string, effectively reduce the eccentric wear of rods and pipes, increase the pumping depth, and increase the crude oil output. The products have been widely used in Daqing Oilfield and Offshore Oilfield Liaohe Oilfield.
The sucker rod anti-drop device is manufactured by a special process. It is installed on the polished rod end and the screw pump end respectively, and is used in series with the sucker rod string. The screw pump can transmit torque when it rotates in the forward direction. When it stops, it can quickly release the energy stored in the rotation of the rod to prevent tripping caused by the reversal of the rod and avoid the risk of injury caused by the polished rod detaching from the rod. The modified products have been widely used in Liaohe Oilfield, Daqing Oilfield, Offshore Oilfield, Shengli Oilfield.
The sucker rod is connected to the universal joint, and the screw pump is connected to the anti-dropping device through the connecting end. A connector is inserted between the universal and the anti-dropping device. The anti-dropping spring group is installed on the anti-dropping device. The universal joint and the anti-dropping device are connected to the screw pump and sucker rod together. It has a stable and firm structure, prevents the screw pump from eccentric vibration, prolongs the service life, prolongs the pump inspection cycle, and improves the oil extraction efficiency.
As a kind of mechanical oil production equipment in the oil field, the screw pump has good adaptability in the exploitation of heavy oil, sand-bearing and high gas-bearing wells, and has the characteristics of small size, convenient installation, and low energy consumption.
Casting cable protectors are widely used in cross joints, tubing, safety valve protection, well completion, fixing, workover and instrument completion. The main body of the cable protector is made by precision casting using high-grade materials to ensure the reliability of the product. The unique streamlined design can prevent damage to the production tubing during dynamic movement and ensure the continuity and accuracy of the complexity of the gauge. Since there are no separate parts or pins, the cable protector can be installed quickly, thereby reducing the risk of hanging. Moreover, it can be easily uninstalled and still allows reinstallation.

It is a positive displacement pump. It relies on the interference fit between the eccentrically moving rotor and the stationary stator to form a sealed cavity that is not connected to each other. Through the rotation of the rotor inside the stator, the sealed cavity extends axially from the inlet of the pump. The end moves to the outlet end, so that the medium in the sealed cavity can be transported by the pump.
