Significant advantages of non-magnetic drill collars

Significant advantages of non-magnetic drill collars

Non magnetic drill collars are a special type of drill collar made of low-carbon, high chromium manganese alloy steel refined through strict chemical composition ratios. This type of drill collar has good low magnetic permeability and high mechanical strength, as well as excellent intergranular corrosion cracking resistance and wear resistance.

Analysis of the Reasons for the Good Performance of the Non magnetic Drill Collar Market

Non magnetic drill collars, also known as non-magnetic drill collars, are a type of non-magnetic drill collar made of austenitic stainless steel or K-Monel alloy. Because it lacks magnetism, it will not affect the direction of the compass. Non magnetic drill collars are often used because they not only have extremely low magnetic permeability, but also have good mechanical properties and corrosion resistance, providing a measurement environment for logging instruments that is not affected by the magnetic field of the drill string. During directional drilling, in order to use a compass inclinometer inside the drilling tool, a certain length of non-magnetic drill collar is connected to the lower part of the drill string, which depends on the inclination angle, azimuth angle, and geographical location of the drilling.

The important role of petroleum drill pipe stabilizer in petroleum drilling

The important role of petroleum drill pipe stabilizer in petroleum drilling

Oil drill pipe stabilizer (also known as stabilizer) is an important tool in oil, natural gas, and geological exploration drilling engineering to prevent well deviation changes. It is connected to a section of drill pipe near the coarse diameter drilling tool to stabilize the drilling direction. During the drilling process, whether it is the inclined section or the inclined section, it is necessary to install several drilling tool stabilizers on the drill string to improve the quality of the wellbore and drilling speed, and reduce drilling costs.

The important role of drill collars in oil drilling

Drill collars are important drill string components in petroleum and geological drilling. They are located at the bottom of the drill string and are the main component of the lower drilling tool assembly. Its characteristic lies in its large wall thickness, which is generally equivalent to 4-6 times the thickness of the drill pipe wall, and it has a large gravity and stiffness.
