The company has independently developed a comprehensive suite of continuous sucker rod operation equipment, which has been successfully deployed in over 3,000 wells across major domestic oilfields with proven performance. In 2023, this complete equipment set was exported to Albania, marking a significant breakthrough in our overseas market expansion. This milestone serves as a testament to the international recognition of our high-end oilfield equipment manufacturing capabilities.
This equipment facilitates one-stop core operations for steel continuous sucker rods, including running, pulling, and fishing. Compared to conventional rod string operations, it increases single-well operational efficiency by over 30%. This significant improvement effectively minimizes well occupation time, substantially reduces labor intensity, and enhances both operational safety and the overall level of automation.
In terms of R&D, this equipment series has secured 3 invention patents and 6 utility model patents, demonstrating outstanding proprietary intellectual property advantages. Leveraging deep industry expertise and technical influence, HIGHLAND Company serves as the primary drafting unit of the SY/T 7335 "Continuous Sucker Rod Operation Equipment" industry standard. This pivotal role highlights our leadership in driving industry technical development and establishing benchmarks in the continuous rod operation equipment sector.
Continuous sucker rod operation equipment is classified into three structural types based on wellsite conditions:
Requires only two main vehicles on site (power unit + transport/welding unit), featuring compact footprint, high integration, and quick mobilization, especially suitable for clustered well pads with limited space.
Requires three main vehicles on site (crane + power unit + transport/welding unit), suitable for high wellhead wells, wells with existing derricks above the wellhead, or well testing operations to reduce workover costs.
Composed of multiple modules (hydraulic power unit, injector head, guide tube, welding machine, reel support, toolbox, etc.), suitable for offshore platforms and complex well conditions.
The equipment delivers a maximum pulling force of 130 kN and is suitable for well conditions up to 3,800 meters in depth, fully meeting the requirements of heavy-duty oilfield operations.
Maximum welding area: 750 mm². On-site weld strength matches the base material.
With a maximum rod running speed of 30 m/min, this system improves single-well operation efficiency by over 30% compared to traditional processes.
Fully mechanized operation eliminates manual coupling handling, significantly reducing human intervention. Crude oil on the rod surface remains in the well, ensuring clean, environmentally friendly operation and reducing workload.
An integrated enterprise combining R&D, manufacturing, and service of continuous sucker rods.
SY/T 6585 "Continuous Sucker Rod" and SY/T 7335 "Continuous Sucker Rod Operation Equipment."
Extensive one-stop service experience in continuous sucker rod running, pulling, fishing, welding, well reaming, and cutting operations.
