High Performance Internal Hook For Smooth Cable Salvage In Oil Wells

Product Specification

Product overview

The inner hook produced and sold by our company Huichi petro is a salvage tool designed for oilfield drilling operations. It is a core tool dedicated to salvaging tubular or hollow objects (such as drill pipes, casings, tubing, etc.) in the well. It adopts high-strength alloy steel integrated forging and barbed hook tooth design, which can accurately lock the inner wall of the object under complex well conditions. It has high temperature resistance, impact resistance, and anti-jamming performance, which greatly improves the salvage efficiency and reduces the operation risk.

Working principle

The working principle of the inner hook produced and sold by our company Huichi petro is based on a clever mechanical structure design. When the inner hook is lowered to the position of the object in the well with the drill pipe, the operator opens the claw of the inner hook by controlling the rotation and up and down movement of the drill pipe. When the claw reaches the appropriate position, the drill pipe is rotated in the opposite direction, and the claw will shrink inward and tightly grasp the object. At this time, slowly lift the drill pipe, and the inner hook can safely salvage the object to the ground. The whole process can achieve effective capture of objects of different shapes and sizes through precise operation control.

Core functions

• Capturing tubular objects: For hollow objects such as broken drill pipes and casings, stable capture is achieved through inner wall anchoring.
• Working in narrow spaces: Suitable for small boreholes, curved well sections and other restricted environments, with a minimum operating well diameter of up to Φ40mm.
• Tolerance to extreme working conditions: Supports high temperature and high pressure environments (-30℃~180℃), is resistant to hydrogen sulfide corrosion, and is suitable for deep well and ultra-deep well operations.
• Easy to operate: The inner hook is simple and convenient to operate, can be quickly installed and disassembled, and improves operating efficiency.

Product structural features

1. Material and process:

    o Main body material: Made of high-quality high-strength alloy steel, it has undergone a special heat treatment process, which greatly enhances the strength and toughness of the inner hook. Whether facing hard metal objects or withstanding the huge pulling force during the salvage process, the inner hook can maintain structural integrity, is not easy to deform or damage, and ensures repeated use.

    o Hook tooth design: spiral barbed hook tooth layout, automatically embedded in the inner wall of the object after grabbing to prevent slipping; the hook tip is blunted to avoid damaging the well wall.

2. Technical parameters:

    o Specification range: Φ25mm-Φ200mm (support non-standard customization)

    o Maximum tensile load: 300kN-1200kN

    o Connection interface: API standard REG, FH and other threads, suitable for mainstream drilling tool combinations

3. Safety design:

    o Built-in anti-stuck mechanism, can be manually unlocked when encountering obstacles to prevent tools from being stuck in the well.

    o Passed API 7-1, ISO 9001 certification, in line with international drilling safety regulations.

Product advantages

1. Precise adaptation: The unique hook claw design and precise operation control enable the inner hook to achieve high-precision grabbing of the object. During the salvage process, it can accurately grasp the key parts of the object, avoid secondary damage to the object during the grabbing process, and also improve the success rate of salvage.
2. High efficiency and durability: reuse times ≥ 30 times, maintenance cost is 20% lower than similar products.
3. Fast delivery: regular specifications are shipped within 72 hours, and urgent orders are responded to within 24 hours.

Application scenarios

The inner hooks produced and sold by our company Huichi Petro are widely used in various oilfield drilling operations. In the daily drilling process, if the drill pipe, casing and other parts fall off, the inner hook can be quickly put into use and quickly salvage and resume operations; tools and parts that fall into the well during the maintenance and replacement of oilfield equipment can also be salvaged by the inner hook. In addition, for some complex old well repair operations, the inner hook can also play an important role and help solve the problem of falling objects in the well.
