Applications

SJ Petro's traveling systems are deployed across a broad spectrum of oilfield operations:

• Oil & Gas Well Drilling – Complete hoisting for drilling operations from 1,000m to 9,000m depth. The traveling system provides the lifting power to raise and lower the drill string, change bits, and run casing.

• Workover Operations – Raising and lowering tubing, sucker rods, and downhole tools for well servicing and maintenance. XJ series traveling systems are specifically designed for workover applications.

• Casing Running – The hoisting system supports the weight of casing strings during running and cementing operations. On larger rigs, line tensions over a million pounds are not unusual.

• Fishing Operations – Precision retrieval of lost tools and equipment from the wellbore requires reliable, controllable hoisting.

• Offshore Platform Operations – Traveling systems for offshore drilling and workover rigs, built to marine-grade standards.

• Desert & Extreme Environment Operations – Specialized configurations for high-temperature, high-cold, and harsh environment conditions.

Frequently Asked Questions

Q: What is a drilling rig traveling system?

A: The traveling system—comprising the crown block, traveling block, hook, and wire rope drill line—is the hoisting mechanism of the drilling rig. It works with the drawworks to raise, lower, and suspend the drill string, casing, and downhole tools.

Q: What is the difference between a crown block and a traveling block?

A: The crown block is positioned at the top of the mast and remains stationary. The traveling block moves up and down the mast and is connected to the hook. Together, they form a block and tackle system that multiplies the lifting force of the drawworks.

Q: What traveling system configurations are available?

A: SJ Petro offers traveling systems in 3×4, 4×5, 5×6, and 6×5 configurations, depending on the rig model and operational requirements.

Q: What is the maximum hook load of SJ Petro traveling systems?

A: SJ Petro traveling systems cover maximum hook loads from 675 kN to 2,250 kN, with traveling hook models available from 1,100 kN to 2,250 kN capacity.

Q: What wireline diameters are available?

A: SJ Petro traveling systems are available with wireline diameters of φ22 mm, φ26 mm, φ29 mm, and φ32 mm.

Q: Are SJ Petro traveling systems API certified?

A: Yes. SJ Petro's traveling blocks and hooks are manufactured in accordance with API Spec 8C. The company also holds API 4F, 7K, 6A, and 16C certifications.

Q: What is the integral traveling block and hook design?

A: The integral design shortens the length between the traveling block and hook, making the best use of the traveling space for the lifting system. This provides increased vertical travel and reduced risk of interference.

Q: Do you offer OEM or customized solutions?

A: Absolutely. We offer comprehensive customization including traveling system configuration, hook load capacity, wireline diameter, component selection, and retrofit solutions for existing rigs.

Q: What is your manufacturing capacity?

A: SJ Petro has a complete production facility with more than 2,100 sets of precision equipment. We produce 200 models of products across four major categories and 12 series.

Q: Do you provide after-sales support and spare parts?

A: Yes. We offer comprehensive after-sales support including spare parts supply, equipment inspection, testing, and major overhaul services.
