The sucker rod is an important part of the spare parts of the oil drilling rig. The main function of the sucker rod is to transmit the power of the ground pumping unit to the downhole pump, drive the piston of the pump to move up and down, and thus achieve the purpose of lifting the crude oil from the well to the ground.
Yilait sucker rod raw material control:
Material of the sucker rod: Low-quality carbon steel, nickel-molybdenum alloy steel, alloy steel.
Tensile strength: 621-1295.
Lower yield strength: ≥414, ≥793.
Percentage reduction in cross-sectional area: ≥45.
Surface hardness (HRC) : ≥42
As a sucker rod manufacturer, we will test each raw material to ensure that all our products are qualified before leaving the factory. Let all drilling companies and oil companies be more efficient in oil operations.
Classification of Yilait’s high-quality sucker rods:
- 1. Anti-corrosion sucker rods:
PE semi-coated anti-corrosion sucker rods are anti-corrosion sucker rods with an ultra-high molecular polyethylene anti-corrosion layer coated on the sucker rod body, and a nickel-based alloy spray-welded on the head within a certain length range. It consists of a PE-coated rod body, a fully spray-welded rod head, and an anti-biased spray-welded hoop. It is suitable for corrosive oil wells and can be using within a well depth of 1,700 meters. The working temperature should be lower than 80°C.
- 2. Full spray-welded anti-corrosion sucker rods:
Fully spray-welded anti-corrosion sucker rods have good mechanical properties and super corrosion resistance. The spray coating material is nickel-basing powder. It adopts advanced overall spray-welding technology. The spray-welded layer and the substrate are melted into one, with strong bonding force, which extends the service life of the sucker rod. The fully spray-welded anti-corrosion sucker rod is anti-corrosion, wear-resistant, and high-temperature resistant. It is suitable for wells with complex well conditions such as severe corrosion, high temperature, and severe wax deposition, and is not limiting by temperature.
- 3. Wax scraping sucker rod:
- 4. Straightening sucker rod:
We can inject 2-3 straighteners on the sucker rod body according to requirements.
- 5. Weighted sucker rod:
Used for the counterweight of the sucker rod column for downhole operation, improve the stress condition of the sucker rod, prevent the eccentric wear of the pipe and rod, and extend the service life of the sucker rod.
6. Pony rod:
Spray welding bare rod has good mechanical properties and strong corrosion resistance. The spray welding layer has excellent corrosion resistance (anti-corrosion of H2S, CO2, CL-, water, etc.), anti-scaling and good wear resistance. The spray welding layer is fusing into one with the rod body and has strong bonding force, which extends the service life of the bare rod.
- 7. Continuous sucker rod pony rods:
The continuous sucker rod is a steel sucker rod with a semi-elliptical cross-section and a circular cross-section. The weight of the entire sucker rod column is reducing by 8-10%. Reduce the flow resistance in the oil pipe, improve the pump efficiency, and increase the output. It can be using for small diameter oil pipes to save oil pipe costs.
- 8. Hollow sucker rod pony rods:
The hollow structure can be injected with hot oil, hot water, steam and various chemicals, and can also be used to lay heating cables. Hollow sucker rods are particularly suitable for heavy oil wells, sand-containing wells and pumping wells that require continuous injection of media.
- 9. Special sucker rod for screw pump:
The torque rod is specially designing for screw pump wells and is suitable for screw pump well oil production under general or slightly corrosive well conditions. It includes HY grade (taper thread) torque rod and HY grade plug-in stop torque rod.
Precautions for use and maintenance of sucker rods:
- 1. Choose the right model: According to the depth, output, crude oil properties and type of pumping unit, choose the right specifications and models of sucker rods to ensure that they can meet the requirements of oil well production.
(Contact Elite engineers to recommend sucker rod models)
- 2. Installation and removal: When installing the sucker rod, strictly follow the operating procedures to ensure that the sucker rod is firmly connecting and well sealing. When disassembling the sucker rod, pay attention to protecting the threads of the rod body and the coupling to avoid damage.
- 3. Daily maintenance: During use, the sucker rod needs to be checked regularly to check whether the rod body has defects such as wear, deformation, cracks, and whether the coupling is loose. At the same time, pay attention to lubrication and anti-corrosion treatment of the sucker rod to extend its service life.
Fault handling: When the sucker rod fails, such as breaking, severe wear, etc., it must be handled in time. For the broken sucker rod, it must be salvaged as soon as possible and replaced with a new sucker rod; for the sucker rod with severe wear, it must be repaired or replaced according to the situation.
