摘　　要：研究不同油井环境下各种管杆配对材料的磨蚀规律,可以指导油田正确选择使用管杆配对材料.笔者通过油井管杆磨蚀试验机,对常用的管杆材料进行了耐磨蚀性能对比实验,并探讨了油井温度、径向载荷等因素对常用管杆材料磨蚀率的影响.实验结果认为,非调质钢接箍与涂料油管配对使用时耐磨蚀性最佳;随着温度的升高,管杆磨蚀率逐渐增大,而当腐蚀介质升高到一定温度时,管杆磨蚀率又有下降的趋势.管杆磨蚀率均随着径向载荷的增加而增大.Study the corrosive-wear rules of the oil tube and pumping rod in different environment can guide technologists through the selection of the suitable tube and rod materials. The effect of the oil temperature and the radial load on the corrosive-wear rate of the traditional tube and rod materials was studied by means of the corrosive-wear experimental tester. The results show that with the increasing of the oil temperature at definite extent, the corrosive-wear rate of the rod and tube materials become larger and larger. The heavier the radial load acts on the tube and rod, the higher corrosive wear rate of the materials has.
