Fishing Magnet For Easy Salvage Of Small Objects In Petroleum And Geological Drilling
________________________________________
Product overview
The oilfield drilling equipment Fishing Magnet produced and sold by our company Huichi petro is specially designed for salvaging metal objects in oilfield downhole operations. This product is made of high-performance permanent magnetic materials and has extremely strong magnetic force. In a complex drilling environment, when metal parts such as drill bits and drill rods accidentally fall, the fishing magnet can quickly locate and absorb metal objects, such as drill bits, drill rod fragments, tools, etc., with strong magnetic force, effectively avoiding drill jams and blockages during drilling, avoiding obstacles to subsequent drilling operations, and ensuring the smooth progress of oilfield mining.

Working principle
When the Fishing Magnet is lowered into the well and close to metal objects, its strong magnetic field will attract metal. The magnetic lines penetrate the surrounding drilling fluid, rock debris and other media, interact with the metal objects, and magnetize the objects and absorb them on the surface of the magnet. By connecting with the drill string, the fishing magnet can safely lift the absorbed metal objects to the ground.

Core functions and advantages
1. High-strength magnetic adsorption
o Using rare earth permanent magnet materials (such as NdFeB), the magnetic strength can reach more than 12,000 Gauss. It is specially designed for complex underground environments and can efficiently adsorb various ferromagnetic metal fragments (such as drill bit fragments, bolts, etc.).
o High temperature and high pressure resistance: Adapt to extreme underground environments (maximum temperature resistance of 150℃, pressure resistance of 50MPa) to ensure operational stability.
2. Fast salvage and reduce downtime losses
o Simplify the traditional salvage process, directly adsorb metal impurities through magnetic force, avoid drilling interruptions caused by foreign body blockage, and improve operational efficiency by more than 30%.
3. Flexible adaptation
o Provide a variety of sizes (Φ50mm-Φ200mm), compatible with different well diameters and drilling tool types, and support fast installation and disassembly.
4. Safe and reliable, reducing risks
o Equipped with anti-drop locking device to avoid secondary pollution; multi-layer anti-corrosion treatment of surface coating can effectively resist the erosion of hydrogen sulfide, salt water, etc., and extend the service life.

Application scenario
The oilfield drilling equipment salvage magnets produced and sold by our company Huichi petro are widely used in various oilfield drilling operations, especially when metal objects fall during drilling, they can be quickly salvaged to avoid interference with drilling operations. At the same time, it is also suitable for other industrial fields that need to salvage metal objects. Including the following scenarios:
- Recovery of metal fragments in drilling operations: used to remove iron chips generated by drill bit wear and protect the integrity of downhole equipment.
- Tool recovery during completion and workover: quickly recover lost tools and reduce non-productive time (NPT).
- Preventive maintenance: regularly clean the wellbore to reduce equipment failure rate and extend drilling cycle.
