Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling, in particular to a hydraulic stabilizer for oil directional drilling. Background Art

[0002] Directional well technology is one of the most advanced drilling technologies in the field of oil exploration and development in the world today. It is a drilling technology that uses special downhole tools, measuring instruments and process technologies to effectively control the wellbore trajectory, so that the drill bit can drill in a specific direction to reach the predetermined underground target. The use of directional well technology can make the oil and gas resources with limited surface and underground conditions economically and effectively developed, can greatly increase oil and gas production and reduce drilling costs, is beneficial to protecting the natural environment, and has significant economic and social benefits.

[0003] A utility model with patent number CN218716581U disclosed a hydraulic stabilizer for oil directional drilling, which is provided with a hydraulic cylinder, an output shaft, a push plate, a guide rod and a slide plate. The hydraulic cylinder extends the output shaft at its output end, drives the push plate to move, and trims and limits the drill rod to prevent the drill rod from shaking back and forth and causing unstable drilling, thereby ensuring the quality of drilling. When the push plate moves, the slide plate moves on the outer surface of the guide rod, thereby increasing the support effect on the push plate, making its movement more stable and the accuracy enhanced.

[0004] The above patent extends the output shaft at its output end through a hydraulic cylinder to drive the push plate to move, thereby trimming and limiting the drill rod. The two push plates can only be used to rest and position the two sides of the drill rod, while there are no limiting measures on the other two sides of the drill rod, and the drill rod may still be offset.
