Dynamics of Pipeline Pulling Process By Horizontal Directional Drilling

[摘要] For using in horizontal directional drilling, the authors developed a model of a cyclical pipeline pulling process, enabling to perform calculations of resistance forces of pipeline movement considering the well profile geometry, mass characteristics of drill pipes, pulled pipeline and mud, as well as the velocity parameters of pullback. Analytical dependences were derived to determine absolute values and time changes in pipeline pullback force considering the well geometry, physical properties of interacting elements of the pullback process. In addition, analytical dependences were obtained for certain power consumptions of a drilling rig during pipeline pulling considering the pullback process model.
