Description

Technical Field

[0001] This utility model belongs to the field of drilling equipment technology, specifically an anti-deviation drill rod guide sleeve. Background Technology

[0002] Drill pipe guide sleeves are key components in drilling or well drilling equipment used to precisely guide the movement of drill pipes. Their core function is to ensure the stability, coaxiality, and safety of drill pipes during drilling, lifting, or lowering. They are widely used in oil and gas drilling, geological exploration, mining, pile foundation construction, and other scenarios.

[0003] By precisely matching the inner diameter of the drill rod with the outer diameter of the drill rod, the drill rod is forced to drill along the preset axis, avoiding borehole deviation caused by the weight of the drill rod, uneven formation, and drilling pressure deviation. During the connection of multiple drill rod sections or the insertion of casing, the guide sleeve ensures that the drill rod is coaxial with the drill spindle and the center line of the borehole, avoiding thread damage or drill rod jamming caused by uneven force at the joint.

[0004] After prolonged use, it was found that when calibrating drill pipes, traditional drill pipe guide sleeves require the replacement of corresponding drill pipe guide sleeves for different specifications of drill pipes, which is inconvenient for size adjustment and affects the use and adjustment of drill pipe guide sleeves.

[0005] Therefore, this utility model provides an anti-deviation drill rod guide sleeve. Utility Model Content
