摘　　要：七棵树油田水平井的应用,加大了抽油杆的载荷,对抽油杆抗拉强度、收缩率、伸长率等提出了更高的要求。笔者为有效适应水平井举升工艺,优化了组合结构,降低了最大载荷,提高了抽油杆的抗拉强度,延长了抽油杆的使用寿命,为水平井在七棵树油田的高效开发,提供了保证。优化后的杆柱结构在现场使用中获得了较好的效果,具有较高的推广价值。The application of seven tree oilfield horizontal well increases the load of sucker rod,tensile strength,elongation,and shrinkage rate are proposed with higher requirements.In order to effectively adapt to the horizontal well lifting technology,the author optimizes the structure,reduces the maximum load,improves the tensile strength of pumping rod,prolongs the service life of the oil pumping rod,which provides a guarantee for horizontal well in seven tree of oilfield development.The optimized structures of rod string in use at the scene has got good results and high spreading value.
