Description

Technical Field

[0001] The invention belongs to the technical field of non-magnetic drill collar processing, in particular to a non-magnetic drill collar production and processing device and an operation method thereof. Background Art

[0002] Non-magnetic drill collars are mainly used in drilling work in the oil, gas, geology and other industries. Non-magnetic drill collars have good low magnetic permeability characteristics, which can reduce the interference of the earth's magnetic field on the drill collars. Therefore, they are widely used in magnetic measurement instruments to ensure the accuracy of measurement data.

[0003] During the drilling process, the non-magnetic drill collar is installed between the drill bit and the drill pipe to transmit torque and withstand pressure. It can help the drilling operation locate the wellbore direction more accurately, thereby meeting the drilling project's requirements for wellbore trajectory control.

[0004] Non-magnetic drill collars are made of a low-carbon, high-chromium-manganese alloy steel. They are refined after strict chemical composition ratio and forged to achieve mechanical properties. They have good low magnetic permeability, high-strength mechanical properties, excellent intergranular corrosion cracking resistance and excellent wear resistance.

[0005] In the prior art, when processing drill collars, the outer ring wall of the drill collar is generally polished by ball rolling to increase corrosion resistance and friction resistance. However, the existing rolling operation has the following problems: First, when using ball rolling, the ball and the inner wall of the protruding end are in close contact. When adding lubricating oil, it is generally sprayed directly on the surface of the drill collar. In order to ensure its comprehensiveness, a large amount of lubricating liquid needs to be sprayed. Because the lubricating oil is easy to slip, it causes waste, resulting in reduced lubrication efficiency at the rolling point, affecting its rolling effect; second, after long-term use, the lubricating oil on the surface of the ball and the impurities on the surface of the drill collar itself will cause stagnation, which will increase the wear of the ball surface and affect the subsequent rolling effect.

At this time, when the rolling ball 19 is sprayed with lubricating oil by the oil spraying component in the fine cavity 17, the surface of the rolling ball 19 is covered to ensure the rolling lubricity. The outer surface area of ​​the rolling ball 19 is small, and the amount of lubricating oil required for its coverage is small. Moreover, because the rolling ball 19 is not directly in contact with the inner arc surface 35, the lubricating oil on the rolling ball 19 will not be scraped off by the inner arc surface 35 when the rolling ball 19 is in rolling contact with the outer surface of the drill collar.

At this time, the inner pressure wheel 62 and the outer pressure wheel 61 are in a non-connected state, so only the outer pressure wheel 61 is in a rotating state. When the rolling ball 19 is in a non-working state, the rolling ball 19 needs the outer pressure wheel 61 to rotate to drive it to rotate. The inner pressure wheel 62 will drive the outer pressure wheel 61 to rotate through the connecting piece, and then drive the rolling ball 19 to rotate, and the scraper plate 51 contacts the rolling ball 19 and scrapes the material.

[0029] The pushing unit includes an L-shaped rod 55. Two symmetrically distributed L-shaped rods 55 are arranged in the rough cavity 18.
