摘　　要：在塔河油田超稠油区块,有杆泵无法满足稠油入泵要求。通过应用深抽抗稠油电泵配合尾管悬挂技术,超稠油开发取得了良好的效果。该技术目前累计应用187井次,但由于小套管尺寸的限制,依然有56口电泵井未配套尾管悬挂,生产中平均运行寿命仅337 d,远低于加装尾管悬挂井的542 d。通过对国内所用尾管悬挂的套管进行研究,优选强度高、防腐蚀、适合塔河油田开发特点的套管,改造设计了一种铝镁合金尾管及接箍为147 mm的139.7 mm的套管,可同时满足在193.675 mm和177.8 mm套管井中尾管悬挂,在现场成功应用了13井次,最终形成了成熟可靠的超稠油电潜泵尾管悬挂技术,对塔河油田超稠油区块的开发具有一定的指导意义。In Tahe ultra-heavy oil block,the rod pump cannot meet the requirements of heavy oil pumping.Through the application of deep pumping electric pump for heavy oil and its coordination with tail pipe suspension,the development of ultra-heavy oil has achieved good results.Up to now,this technology has been used in wells for 187 times.However,due to the limitation of the small casing size,56 electric pump wells are still not equipped with tail pipe.The average operation life in production is only 337 d,which is far lower than that of wells equipped with tail pipe electric pump,542 d.Based on the investigation of the casing used in China,the casing with high strength,anti-corrosion and suitable for the development of Tahe oilfield is selected.A kind of aluminum magnesium alloy tail pipe and 139.7 mm casing with 147 mm pitch collar are designed.It can be suspended in both 193.675 mm and 177.8 mm cased wells and has been successfully applied in wells for 13 times in the field.Finally,the mature and reliable suspension technology of tail pipe equiped by electric submersible pump for ultra-heavy oil is formed,and has certain guiding significance for the development of Tahe ultra-heavy oil block.
