String Magnet

The high-efficiency strong magnetic fishing tool is used to recover the iron scraps and dirt produced in the process of oil, geological drilling and casing repair, which cannot be returned by the circulating liquid. The mag netic debris is adsorbed on the outer pipe at the position of the magnetic ring, and cannot be sucked up throu gh the circulation and deposited in the recovery cylinder to be taken out of the well.

Detailed Description

APPLICATION
The high-efficiency strong magnetic fishing tool is used to recover the iron scraps and dirt produced in the
process of oil, geological drilling and casing repair, which cannot be returned by the circulating liquid. The mag netic debris is adsorbed on the outer pipe at the position of the magnetic ring, and cannot be sucked up throu gh the circulation and deposited in the recovery cylinder to be taken out of the well.

FEATURES AND BENEFITS
1. Simple Structure, convenient operation and reliable performance.
2. High temperature model also avliable.
3. The design enables drillstring rotation while the magnet section remains stationary, which reduces casing wear and minimizes the risk of debris becoming detached.
4. By using the permanent magnet with itself, the small pieces of falling objects are sucked up, so as to effec tively salvage such falling objects and achieve the purpose of purifying the bottom of the well.
