摘要
针对油田高含水期开采井液所具有的特点 ,合理选择抽油泵泵筒和柱塞摩擦副的材料及表面处理工艺 ,可提高抽油泵的使用寿命。选择泵筒材料及工艺为碳钢表面镀铬、碳钢表面镀镍磷和 38CrMoAl氮化 ;柱塞材料及工艺为碳钢表面镀铬、碳钢表面镀镍磷、碳钢表面喷焊和38CrMoAl氮化 ,分别配对组成 9对摩擦副在同等条件下进行了耐磨性试验。综合分析试验结果 ,结合摩擦副的摩擦系数 ,认为碳钢喷焊柱塞与碳钢镀铬泵筒配对为最优 ,38CrMoAl氮化柱塞与碳钢镀铬泵筒配对次之。
The abrasion resistance of the barrel and plunger influences directly the life of the subsurface pump. Proper selection of the material and surface treatment technology of this friction pairs can improve the life of the pump operating in high-water-cut wells. Abrasion resistance of 9 friction pairs of various materials with treating technologies was tested, and the result shows that, the carbon steel spray weld plunger and the chrome plated carbon steel barrel pairs is the best in abrasion resistance, and the pairs of nitrided 38CrMoAl plunger and chrome plated carbon steel barrel is the second best.
