Applications

SJ Petro's drilling hooks are deployed across a broad spectrum of oilfield operations:

• Oil & Gas Well Drilling – The drilling hook suspends the swivel and drill string, providing the connection between the traveling block and the rotating equipment. It is used to hoist and trip the drill pipe, replace bits, and run casing during petroleum drilling operations.

• Workover Operations – Raising and lowering tubing, sucker rods, and downhole tools for well servicing and maintenance. The drilling hook is an essential component of XJ series workover rigs.

• Casing Running – The hook supports the weight of casing strings during running and cementing operations.

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

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

• Top Drive Operations – The integral traveling block and hook design helps satisfy the requirements of top drive operation.

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

Frequently Asked Questions

Q: What is a drilling rig hook?

A: A drilling hook is the primary load-bearing component of the rig's hoisting system. It connects the traveling block to the swivel, top drive, or drill string, and is used to hoist and trip the drill pipe, replace bits, and run casing during petroleum drilling operations.

Q: What is the advantage of the integral traveling hook and block 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, reduced risk of interference, and simplified maintenance.

Q: What drilling hook models does SJ Petro offer?

A: SJ Petro offers the SYG Series (SYG110, SYG150, SYG170, SYG225) with capacities from 1,100 kN to 2,250 kN, and the YG Series with capacities from 900 kN to 4,500 kN.

Q: What is the maximum hook load of SJ Petro drilling hooks?

A: SJ Petro drilling hooks cover maximum hook loads from 1,100 kN to 2,250 kN (SYG Series), with YG Series models available up to 4,500 kN.

Q: What safety features are included on SJ Petro drilling hooks?

A: SJ Petro drilling hooks are equipped with a reliable safety device, a braking device to lock up and lock out the body, and spring and hydraulic buffering devices for protection of drill pipe joints.

Q: Are SJ Petro drilling hooks API certified?

A: Yes. SJ Petro's drilling hooks are manufactured in accordance with API Spec 8C (Drilling and Production Hoisting Equipment). The company holds API 4F, 7K, 8C, 6A, and 16C certifications.

Q: Can drilling hooks be used on both drilling rigs and workover rigs?

A: Yes. SJ Petro's drilling hooks are designed for use with both drilling rigs and workover rigs, with reliable quality and large versatility.

Q: What is the difference between a drilling hook and a traveling hook?

A: A drilling hook is the load-bearing hook component that connects to the traveling block. A traveling hook typically refers to an integral unit where the traveling block and hook are combined into a single assembly. SJ Petro offers both configurations.

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

A: The integral design combines the traveling block and hook into a single unit, shortening the overall length and maximizing the available traveling space within the mast.

Q: Do you offer OEM or customized solutions?

A: Absolutely. We offer comprehensive customization including hook series, load capacity, integral design options, material selection, safety device configuration, and retrofit solutions for existing rigs.

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.
