摘要
考虑井眼轨迹、杆(管)柱构成及杆(管)柱与管(井)壁的滑动摩擦力,建立了定向水平井杆(管)柱纵向振动的微分方程。分别给出有杆泵抽油系统动态参数诊断、预测,钻进过程中钻柱的纵向振动和起下杆(管)柱时杆(管)柱纵向振动的定解条件。
Taking the pathway of hole,the make-up of rod(pipe) string and the friction between rod (pipe) string and tubing (wellbore) wall into account,the differential equation for the longitudinal vibration of down-hole string in a directional horizontal well is established,and the rated conditions for the diagnosis and prediction of the dynamic parameters of sucker rod pumping system and for the calculation of the longitudinal vibration of rod(pipe) string in tripping operation or that of the drill pipe in drilling operation are given respectively.
