Product Description
The friction between the sucker rod and the tubing, as well as the friction between the sucker rod coupling and the tubing, can cause the rod to break or trip, leading to the shutdown of the oil well. This results in string leakage and tubing scrapping, causing significant economic losses in oilfield production. This device integrates advanced technologies, optimized specifically for the characteristics of eccentric wear in oil extraction wells. Developed as a specialized anti-wear solution, it excels in severely eccentric wear oil wells through two core processes: improving the self-lubricating ability of the rod coupling and increasing the friction contact area. It not only protects the device body from wear but also significantly reduces oil pipe wear, achieving a service life more than ten times that of ordinary stabilizers.
Structure & Working Principle
The device consists of a triangular fan-shaped self-lubricating alloy spray straightening body, an extended sucker rod coupling, and a fixing ring. The triangular fan-shaped stabilizer is fitted onto the extended coupling of the sucker rod and secured with the fixing ring. The supporting body slides freely on the extended coupling of the sucker rod. Its innovative triangular shape enables the supporting body to rotate automatically, ensuring that the wear-resistant surface matches the inner wall of the oil pipe.
Main Features
Significant Self-Protection: The unique self-lubricating additive component of the stabilizer sleeve reduces the friction coefficient between the coupling and the oil pipe, playing an essential self-lubricating role while protecting and slowing down the wear of the oil pipe surface.
Eccentric Wear Protection: The stabilizer sleeve adopts a special eccentric structure design. This design overcomes the disadvantages of short eccentric wear cycles and oil pipe damage typically caused by point and line contact in standard stabilizers, greatly reducing sucker rod wear.
Frequently Asked Questions (FAQ)
What causes sucker rod breaking and tubing damage in oilfields?
Friction between the sucker rod/coupling and the tubing leads to eccentric wear. This wear causes rod breaks, trips, string leakage, and eventual scraping of the tubing, leading to production shutdowns and high economic losses.
How does this device reduce wear on the oil pipe?
The stabilizer sleeve incorporates a unique self-lubricating alloy spray coating with self-lubricating additives. This drastically reduces the friction coefficient between the coupling and the pipe, protecting the pipe surface from severe wear.
What are the main components of this anti-wear device?
The assembly consists of a triangular fan-shaped self-lubricating alloy spray straightening body, an extended sucker rod coupling, and a fixing ring that holds the components securely in place.
What is the advantage of the triangular fan-shaped design?
The triangular shape allows the supporting stabilizer body to rotate automatically on the coupling. This ensures that the wear-resistant surface continuously matches the inner wall of the oil pipe rather than wearing down a single point or line.
What is the coating specification of the stabilizer?
The coating applied has a high hardness index of 50 to 63 HRC and features a thickness of ≥0.25 mm, providing premium wear protection and a lifespan ten times longer than standard stabilizers.
What materials and processes are used to manufacture the device?
The device is manufactured using a high-quality Casting process with Cast Steel material. The surface undergoes a specialized Sand Blast treatment to ensure coating adhesion and component durability.
