摘要
根据侧钻水平井的作业过程,考虑井眼轨道、作业管柱的重力、液体的浮力、作业管柱与井壁的摩擦力等因素的影响,建立了侧钻水平井作业管柱的稳态拉力和扭矩模型,结合大庆油田第一口侧钻水平井的设计过程,给出了该模型的应用实例。
Based on the considerations of sidetracking horizontal well workover procedures, wellbore track, weight of tubing string, fluid buoyancy and friction between well wall and pipe string, pipe string steady state tension and torque physical models were built. The paper describes the model applications in the design work of first side tracking horizontal well in Daqing Oil Field.
