Product Overview

Releasing Spear is the core tool used for internal salvage in oilfield drilling and repair operations. It is designed for precise capture and recovery of drop fish from wells (such as fracture casing, drilling rods, oil pipes, etc.). It uses high-strength alloy material and precision spiral tiles structure, and can achieve reliable grasping through the internal occlusion mechanism. It is suitable for high pressure, high temperature and complex well conditions, significantly improving salvage efficiency and operation safety. It is not possible in oilfield rescue and well repair operations. or lack of professional equipment.

Working Principle

The working principle of Releasing Spear is designed with unique structural designs such as kali, mandrel, etc., which can be closely linked to the inner wall of the fallen object, and then the fallen object is salvaged to the ground with the help of lifting equipment. At the same time, when special circumstances occur during the salvage process, such as the fallen object being stuck and cannot be salvaged smoothly, the retractable structure of the retractable spear can safely separate it from the fallen object, avoiding the tools and fallen objects being trapped in the well together. It effectively ensures the smooth progress of salvage operations and reduces economic losses and operation delays caused by falling objects.

Core Functions And Features

1. High-precision internal grabbing technology

• Spiral caulking design: built-in spiral taper caulking, which adaptively expands and tightens the inner wall of the fish through rotation operation, and the grip force reaches more than 200kN to ensure salvage stability.
• Small diameter adaptability: suitable for a variety of casing sizes (5″-13⅜″), compatible with straight wells, horizontal wells and large slope well operations, and adapted to API standard casing (such as J55, N80, etc.).

2. High pressure resistance and corrosion resistance

• It is made of chromium molybdenum steel or nickel-based alloy, which withstands extreme temperatures (-30℃ to 150℃), high pressure (≤10000psi) and acidic media environment, and extends the service life of the tool.

3. Flexible operation and release mechanism

• Supports fast operation modes of left-hand locking and right-hand release, and cooperates with hydraulic disassembly (maximum torque of 300kN·m) or continuous oil pipe (CTU) system to reduce the number of drilling and downs, and improve the operating efficiency by 40%.
• Modular design supports rapid replacement of consumable parts such as tiles and seals to reduce maintenance costs.

4. Intelligent security monitoring (optional)

• Integrate pressure sensor and data transmission unit to monitor and capture load and tool status in real time, and warning abnormalities through ground system to reduce the risk of underground accidents.

Application Scenarios

Releasing Spear is widely used in drilling, well repair and other operations in oil fields, especially when frequent connection and release of downhole tools or equipment, and its efficient and reliable connection and release performance has been widely recognized and applied.

• Casing salvage: Accurately recover underground fractured or stuck casing to restore wellbore integrity.
• Well repair and rescue: Use shock absorbers, shoe grinding and other tools to remove foreign objects in the well and deal with casing deformation problems.
• Discarded well sealing: Quickly recycle the discarded casing to facilitate subsequent cement sealing and environmentally friendly treatment.
