Abstract

In the deviating section of horizontal well, a greater length of horizontal section leads to a more severe friction and a smaller weight on bit transmitted to bit, which affects the rock breaking power. To address this issue, this paper introduces a novel tool termed the Sliding Drilling Controller (SDC). Subsequently, the modal analysis of axial-torsional coupled vibration is carried out. Then, the dynamic model of the horizontal drill string system is established during sliding drilling and compound drilling to obtain the corresponding dynamic response characteristics of axial torsional coupled dynamic response. The results show that the rig speed and external load should be increased as appropriate when the SDC is connected to the drill string system, which prevents resonance. A judicious increase of weight on bit can enhance the effectiveness of reducing friction and drag. In contrast, increasing rotary torque has minor impact on the reduction of friction and drag. The research offers valuable insights for the practical application and structural enhancement of SDC.

期刊介绍： The International Journal of Non-Linear Mechanics provides a specific medium for dissemination of high-quality research results in the various areas of theoretical, applied, and experimental mechanics of solids, fluids, structures, and systems where the phenomena are inherently non-linear. The journal brings together original results in non-linear problems in elasticity, plasticity, dynamics, vibrations, wave-propagation, rheology, fluid-structure interaction systems, stability, biomechanics, micro- and nano-structures, materials, metamaterials, and in other diverse areas. Papers may be analytical, computational or experimental in nature. Treatments of non-linear differential equations wherein solutions and properties of solutions are emphasized but physical aspects are not adequately relevant, will not be considered for possible publication. Both deterministic and stochastic approaches are fostered. Contributions pertaining to both established and emerging fields are encouraged.
