Description

Technical Field

[0001] The utility model relates to the technical field of guide devices, in particular to a guide device for oil drilling pipes. Background Art

[0002] Oil drilling pipes are pipes used to transport the drill bit from the surface to the target formation and recover cuttings and cores during oil drilling. They must be able to withstand high pressure, high temperature and corrosion, and have sufficient strength and durability to cope with harsh underground environments and complex drilling conditions. Oil drilling equipment is used to drill through multiple formations along the designed track from the ground to reach the predetermined target layer (oil and gas layer or possible oil and gas layer), forming a stable channel (i.e. oil and gas well) for oil and gas extraction or injection of the required fluid (water, gas, steam), and completing coring, logging, logging and testing during and after drilling to obtain various information required for exploration, development and drilling. The work of drilling holes from the ground using mechanical equipment or manpower is called drilling. In the process of the pipe entering the oil well, not only a driving device is required, but also a guiding device is required to ensure that the movement trajectory of the pipe is correct and it can correctly enter the designated position in the oil well. The existing guiding device is very simple and cannot accurately and omnidirectionally guide. The guidance is unstable and has large deviations. When lowering the pipe casing, the operator needs to frequently adjust the direction and lower the casing little by little, which is inefficient and labor-intensive.

[0003] In the prior art, some pipe guide devices cannot adapt to the rugged terrain at the drilling site, making the overall structure unstable and easy to tip over during positioning. Some pipe guide devices cannot adapt to a variety of different types of pipe bodies, so different pipe bodies require different machines, which increases the working cost when using different pipe bodies.
