摘　　要：根据传热学和两相流原理，计算了包括圆弧段在内的沿井深的温度和压力分布，算出了最大和最小的悬点载荷，并求得了悬点载荷与井筒电加热强度及抽汲速度间的关系。Based on the theories of heat transfer and two phase fluid flow, the temperature and pressure distribution along depth of wellbore and the curved part of horizontal well are calculated. The maximum and minimum loads of sucker rod hanger are estimated. The relations among load of sucker rod hanger, electric heating intensity of wellbore and suction velocity are obtained. The result of the study can provide a basis for avoiding damage accident of sucker rod and its joint.
