摘　　要：根据多相流体力学的能量守恒原理，从油管和抽油杆的环空入手研究油气水混合物在油管内的压力分布和抽油泵的能量损失，推导出定向井有杆抽油泵入口压力、出口压力、排量系数、泵效之间的关系，从而得到定向井有杆泵抽油井筒压力分布预测模型。计算实例表明，计算精度满足工程要求，对预测定向井的垂直和倾斜井筒压力分布有重要的参考价值。On the basis of the energy conservation of multiphase fluid mechanics,the relations among the pump intake presssure,pump outlet pressure and pumping coefficient are derived for a directional well with a sucker rod pump ,and the predicting models for pressure distribution in a directional wellbore are obtained. The examples show that the precision of the models can meet the requirements of petroleum engineering,and they have an important reference value for oil production.
