Product Description
The Magnetic Fishing Tool is a downhole fishing tool used in oil and gas well operations to retrieve small ferrous metal debris from the wellbore. It utilizes a high-strength permanent magnet to attract and collect metal objects such as broken drill bit fragments, bearings, bolts, and other metallic debris from the bottom of the well.
Tool Definition
The Magnetic Fishing Tool is a specialized tool used to retrieve ferrous objects from the wellbore by utilizing magnetic attraction. It is suitable for recovering small metal debris such as iron filings, steel balls, and other ferrous fragments.
Structural Features
The core adopts a neodymium-iron-boron (NdFeB) high-strength magnetic system. Through a concentric magnetic flux path design, the magnetic force is effectively concentrated, improving the adsorption efficiency.
Technical Parameters
The magnetic pulling force ranges from 30 kg to 800 kg. The tool can be customized according to the wellbore size to meet different operational requirements.
Application Scenarios
It is mainly used to retrieve scattered or small ferrous objects such as roller cone fragments, steel balls, drill bit cones, and iron debris from the wellbore.
Operational Guidelines
Maintain a flushing distance of 3–5 meters, and control the weight on tool to no more than 10 kN to avoid magnetic circuit shorting and ensure effective fishing performance.
