1.Basic Definition
The non-magnetic integral blade stabilizer is a downhole tool used in drilling operations, mainly used to stabilize the drill bit trajectory, control wellbore inclination, and prevent wellbore collapse. Its’ non-magnetic ‘characteristic means that the tool is made of non-magnetic materials and will not interfere with the magnetic field measurement of measurement while drilling (MWD) or logging (LWD) instruments, ensuring the accuracy of directional control and geological guidance.
2.Structural features
Integral structure: The blade and spindle are forged together without threads, providing higher strength and reducing failure rates.
Blade design: typically with spiral or linear blades, used to maintain the gap between the drill bit and the wellbore to avoid sticking.
Non-Magnetic Material: Common materials: non-magnetic stainless steel (such as Monel, Inconel, 15-5PH, Non Mag Stainless)
Characteristics: High strength, corrosion resistance, non-magnetic, good wear resistance.
Surface treatment: The blades can be spray welded with hard alloys (such as tungsten carbide) to enhance wear resistance.
3.Application Fields
Oil &Gas Drilling: used for trajectory control of directional wells, horizontal wells, S-shaped wells, and complex formation wells
Geothermal well drilling: In high-temperature and highly corrosive environments, non-magnetic and high-strength materials are required
Geological exploration and logging: ensuring the accuracy of geomagnetic data measurement, especially in magnetic anomaly formations
Measurement while drilling system (MWD/LWD): Non-magnetic characteristics are a necessary condition for cooperating with measurement tools to avoid magnetic field interference
Deep/ultra-deep well drilling: high structural strength and stability requirements, integrated non-magnetic design is more reliable
