Abstract: To address the issue of excessive friction and torque in extended-reach well operations, which restricts the extension capability of the wellbore and poses safety threats during the operation, this paper adopted an inductive analysis method to systematically review the core influencing factors of friction and torque in extended-reach wells, analyzed the applicable conditions and calculation characteristics of two classic analysis models (soft rope and rigid rod), and comprehensively summarized five types of engineering measures for friction and torque reduction, such as optimizing drilling and completion fluids and designing wellbore trajectories. The analysis reveals that friction and torque is affected by multiple factors such as well deviation and friction coefficient, and when the well deviation exceeds 60°, the contact pressure between the pipe string and the well wall shows an exponential increase. Currently, the research still has limitations in modeling the mechanism of friction and torque and real-time monitoring. The classic analysis models need to comprehensively consider wellbore dogleg severity and drill string rigidity, and intelligent models in complex conditions can improve the prediction accuracy. Based on this, this paper proposes future research directions in multi-physics field coupling modeling, intelligent monitoring, and green friction and torque reduction technology research. The research results can provide support for the precise prediction and effective control of friction and torque in extended-reach wells, and enhance the reliability and economy of extended-reach well engineering design.
