102系列斜井潜油电泵机组抗弯性能试验

Bending resistance test of electric Submersible pump assembly in deviated holes.

抗弯强度是斜井潜油电泵机组能否通过斜井弯曲段 ,通过后能否恢复直线状态且保证机组正常工作的技术关键之一。根据电泵机组通过弯曲段的受力分析与计算 ,确定了机组的造斜曲率和变形量 ,随后选择两节外径为 95mm、长度为 4 8m的潜油电动机进行中间加力的抗弯性能试验。试验结果表明 ,电动机弯曲后几乎不产生变形 ,基本恢复直线状态 ,说明 10 2系列斜井潜油电泵机组可以通过套管内径为 12 3 7mm、造斜曲率为 10°/ 30m的斜井弯曲段 。

Bending strength is of gut importance to ensuring normal operation of electric submersible pump (ESP) assembly. The building curvature and deformation of the ESP assembly were determined according to force analysis and calculation of the assembly passing through the curved portions. Bending resistance test of a ESP assembly with a OD of 95mm and a length of 4. 8m was conducted. The result of the test shows that, series 102 ESP assemblies operate well when passing through a curved portion with a build-up rate of 10°/30m cased with 123 .7mm OD casing.
