AI Technical Summary
Technical Problem
In current drilling projects, the intelligence of drilling tools during navigation is low, especially in complex geological environments where the trajectory cannot be adjusted in time, resulting in insufficient control precision.
Method used
By acquiring drilling environment information and drill bit attitude perception module, trajectory planning, obstacle avoidance and attitude analysis are performed. The attitude perception module is used for direction matching and adjustment to ensure that the drill bit moves stably along the optimal path.
Benefits of technology
It enables intelligent drilling tool navigation under complex geological conditions, improves the intelligence and accuracy of drilling tool trajectory control, and ensures drilling safety and feasibility.

Abstract
本发明涉及钻井工程技术领域，一种基于姿态感知的孔内钻具智能巡航方法及系统，包括：进行轨迹规划，得到方案轨迹，确认出第n个钻进节点坐标，根据第n个钻进节点坐标，对钻井钻具进行调度，得到调度钻井钻具，利用姿态感知模块对调度钻井钻具进行姿态分析，得到姿态预测方向，基于姿态预测方向，获取方向匹配结果，基于方向匹配结果，对调度钻井钻具进行轨迹控制，得到稳定轨迹钻井钻具，令N=n+1，将N作为n，将稳定轨迹钻井钻具作为钻井钻具，并返回上述从多个轨迹点坐标中确认出第n个钻进节点坐标的步骤，直至N=H。本发明可解决当前在对钻具的巡航过程中智能性低的问题。
