107系列高温潜油电机是根据中原油田的生产需要新研制的小直径系列潜油电机。通过参数优化、材料优选与潜油泵的适应性研究,研制成功外径为107mm、绝缘等级为H级的小直径电机,机组轴向投影尺寸112mm,适用于井筒内径大于116mm的套变、缩径与结垢井及150℃高温油井提液,能节约采油成本,增加原油产量,经济效益和社会效益显著

107 series high-temperature submersible motors,which belong to small diameter motors,are developed according to the production practice of Zhong yuan oilfield.With design and optimization of the parameters,selection of materials and study of the adaptability with submersible pumps,little diameter series motors with outside diameter of 107mm and insulation grade of H-degree have been developed.The axial projected size of the units is ?112mm,and can be applied in liquid-lift from oil wells of which the well casing inside diameter of larger than 116mm and there are casing deformation,undergauge,scale formation and high temperature of 150℃.They can not only save oil recovery costs,increase oil production rate,but also create outstanding economic and social benefit.
