[0002] As global demand for oil resources continues to grow, the difficulty of oil extraction is also gradually increasing. To improve oil recovery rates, more complex drilling operations are required, including drilling in deep formations, areas with complex geological structures, and offshore environments. In these situations, the drill bit is easily affected by factors such as formation heterogeneity, changes in rock hardness, and ground stress, causing it to deviate, causing the wellbore trajectory to deviate from the designed target. In traditional drilling, the main control method is the gravity of the drill tool, but this method has low precision and cannot meet the requirements of complex drilling operations. Especially when encountering geological conditions such as inclined formations and faults, the drill bit can easily deviate from the predetermined trajectory. Currently, the anti-deviation drilling guide device on the market is composed of a drill pipe, a clamping block, a guide tube, and other structures. Traditional anti-deviation drilling guide devices have poor guidance effect.
