No magnetic measurement tube
Product Description
In order to ensure an undisturbed magnetically free environment at the bottom of the hole, magnetically free drill pipe is connected at both ends of the front and back of the pipe. The outer pipe of the magnetically free pipe is composed of magnetically free steel, which has the characteristics of low permeability, high tensile strength and good torsional resistance, providing a magnetically free environment free from the magnetic interference of the drilling tool for the measurement system in the hole. The magnetic field at the probe pipe is almost equal to the nearby geomagnetic field. Therefore, the geomagnetic direction of borehole can be accurately distinguished to ensure the measuring accuracy of the measuring system
Product Features
1, non-magnetic: has no magnetic characteristics, its permeability is less than 1.005;
2, good safety performance: impact and friction in the process of no sparks:
3, with high tensile strength and torsional performance: tensile strength ≥1035MPa, yield strength ≥965MPa;
4, good plasticity: fracture elongation is 2~5 times of beryllium copper, can fully reach the level of 135 steel;
5, corrosion resistance: has a strong anti-corrosion and downhole environment adaptability, can be operated in hydrogen sulfide acid high corrosion environment.
Scope of application
The outer pipe is mainly used to cooperate with the measuring pipe.
