Custom External Hook For Precise Cable Salvage In Oil And Gas Exploration

________________________________________

Product overview

The External Hook is a professional tool used for efficient salvage of fallen objects (such as broken drill pipes, casings, metal debris, etc.) in oilfield drilling and well repair operations. It is made of high-strength alloy material and optimized hook body design, and quickly restores the continuity of wellbore operations through precise hooking and locking functions. It is suitable for a variety of well types and complex working conditions (high temperature, high pressure, acidic environment), significantly reducing the risk of stuck drill and downtime losses, and is the core salvage equipment for oilfield rescue and well repair operations.

Working principle

The External Hook produced and sold by our company Huichi petro is usually made of high-strength alloy steel and has the characteristics of durability. Its structural design is unique, and the hook part has been specially treated with good toughness and wear resistance. During the salvage operation, the External Hook is connected to the bottom of the drill pipe and lowered to the location of the fallen object in the well through the drill pipe. The operator controls the rotation and lowering depth of the drill pipe according to the downhole situation, so that the hook part of the outer hook can accurately hook the fallen objects. After confirming that the outer hook has firmly hooked the fallen objects, slowly lift the drill pipe and use the grip of the outer hook to salvage the fallen objects from the well. The design of the outer hook can adapt to fallen objects of different shapes and sizes, which improves the success rate of salvage operations.

Core functions and features

    1. Efficient salvage design

      o Strengthened hook structure: The hook head is forged with wear-resistant alloy steel, and the hook tip angle and curvature are optimized. It can accurately hook the fallen objects in the well (such as fish tops and casing fractures), and the gripping force is more than 150kN.
      o Multi-specification adaptation: Supports API standard casing (5″-13⅜″), adapts to vertical wells, horizontal wells and high-angle well operations, and is compatible with continuous tubing (CTU) and conventional drill pipe systems.

2. Corrosion and wear resistance

      o The material is made of chrome-molybdenum steel or nickel-based alloy, which can withstand high temperature (-30℃ to 150℃), high pressure (≤10000psi) and corrosive environment containing hydrogen sulfide, extending the service life of the tool.

3. Flexible operation mode

      o Rotating outer hook (optional): The hook body can rotate 360°, and cooperate with the jar or hydraulic disassembly frame (maximum torque 300kN·m) to enhance the salvage efficiency and reduce the number of trips.
      o Modular design: The split structure of the hook head and the connecting rod supports the rapid replacement of wear parts, and the maintenance cost is reduced by more than 30%.

4. Intelligent monitoring function (optional)

      o Integrated pressure sensor, real-time feedback of hook load data to the ground system, early warning of overload risks, and ensuring operation safety.

Application scenarios

The External Hook produced and sold by our company Huichi Petro is widely used in drilling operations in various oil fields, including onshore oil fields, offshore oil fields, deep wells, ultra-deep wells, and drilling operations under complex geological conditions. As long as there is a falling object in the well, the external hook can be used for salvage. Common application scenarios include salvaging various downhole tools and equipment components such as drill pipe joints, drill bits, and valves.

• Drilling rescue: salvage broken drill pipes, drill collars and other falling objects in the well to resume drilling operations.
• Well repair operations: remove casing fragments or stuck tools in the well to repair the integrity of the wellbore.
• Abandoned well plugging: Recover metal residues in abandoned wellbore to facilitate environmentally friendly well plugging treatment.
