摘要: 塔河油田原油地面黏度大于100×104mPa·s,油藏埋深超过5700m,随着油田的开发,地层能量不断降低,常规的深抽工艺已难以满足开发需求。该文在分析塔河油田原油物性与井筒温度场的基础上,对电泵结构和性能参数进行优化。通过提升电机的耐温等级、绝缘与密封性能;增强潜油离心泵的抗压强度,提高单级叶导轮扬程,并配套高温电缆、正弦滤波器等技术,研制出了超深抗稠油电泵,并在塔河油田TH10113CH 井成功应用,创造了电泵下深5029.8m的世界纪录。Abstract: In the Tahe Oil Field,surface viscosity of crude oilsis over 100×104mPa?s andreservoirsareburied over 5700m deep.When drilling deeper,formation energy decreases and normal deep-pumping techniques fail to meetwellbore temperature fieldsexploration needs.Based nnanalyses of crude oil physical properties andin the Tahe Oil Field。StYnCtnYeand performance parameters of electricpump wereimproved.Heat resistance,insulation and sealing capacities of motorwere enhanced.Compressive strength of submersiblepump was strengthened.Lift of single-stage impellers and diffusersincreased.Combined with high temperature cable andsine filter technologies,ananti-heavy-oil electric pump wasdeveloped and successfully applied in Well TH10113CHultra-deep andof the Tahe OilField,resulting in the deepest drilling depth in the world,5029.8 m.
