摘要
Abstract
This study focuses on the design of direc-tional drilling operations for crossing high-strength rock formations under complex geological conditions.Highly targeted technical optimization schemes,en-compassing key aspects such as drilling tool systems,rajectory control,and prevention of pipe sticking are proposed.The implementation of these optimized schemes in specific engineering cases has demon-strated their effectiveness in significantly improving drilling efficiency,reducing bit wear rate and drilling tool damage rate,enhancing the accuracy of trajectory control,and effectively strengthening the stability and safety of the drilling process.关键词
