Sharp Razor Straight Magnet
wellbore cleaning tools
INTRODUCTION:
ModelSharp Razor Straight Magnet (including String Magnet & Super String Magnet) is a fishing tool for recovering iron scraps and dirt which are generated during the cleaning operation of petroleum, geological drill and casing repair and cannot be returned by circulating liquid; wherein, magnetic scraps in the dirt will be attached on external pipe in the position of magnetic ring, and those cannot be attached for circulation will deposit inside the recovery barrel and then be brought out of the well. It possesses advantages such as simple structure, convenient operation and reliable performance. It can utilize the permanent magnet of itself to attract small objects which fall off, thus effectively fishing this kind of fallen objects, and realizing the purpose of purifying the bottom hole.
STRUCTURE AND PRINCIPLE:
1. The Sharp Razor Straight Magnet Straight Magnet mainly consists of upper joint, main body, rectangular magnet and lower joint.
2. Its function is to recover dirt which cannot be returned by circulating liquid in the well; wherein, magnetic scraps in the dirt will be attached on magnetic ring, and those cannot be attached will deposit inside the recovery barrel and then be brought out of the well.

Casing Scraper
Manage debris for a variety of applications
The magnet is run downhole on the workstring as part of the cased hole drilling, milling, or polishing assembly. A dedicated flow path prevents restrictions when the magnet is packed with debris.
Displacements, postperforating, prefracturing, multizone completions, milling, burning, fishing, and smart completions are ideal applications for the MAGNOSTAR magnet, especially when there is the potential for a significant amount of ferrous debris.
