摘　　要：根据直井有杆泵抽油有关理论,结合斜井井身轨迹和生产特点,建立了斜井三维井眼中杆柱轴向和侧向载荷计算数学模型,给出了扶正器间距计算方法。按照修正的API抽油杆柱设计方法,研究了斜井抽油杆柱等强度设计方法,给出了设计步骤,形成了斜井有杆泵抽油时机、杆、泵及抽汲参数优化设计方法,编制了相应的设计软件。应用实例表明,该优化设计方法理论正确可靠,为工程人员提供了科学准确的设计工具。Based on related theory of oil pumping with rod in vertical well and combining with feature of deviating hole track and production feature, mathematic model for calculating load of axis and side direction of rod in three dimensions of deflecting well is created and the method to calculate the space of the stabilizer is provided. According to modified designing approach for API oil pumping rod, the paper studies the designing way for stress of pumping rod in deviating well, gives out its procedures and forms an optimal design and approach for unit, rod and pump of oil pumping system and its swabbing parameters in deviating well and compiles a corresponding software. Actual examples show that the theory of this method is right and reliable which provides a scientific and accurate designing tool for engineers.
