Abstract: Tarim Oilfield is characterized by ultra-deep reservoir and ultra-heavy crude oil. So heavy oil here has gel asphalt deposition and high frictional resistance. In addition, the temperature is high in bottom hole, as a result the conventional submersible electric pumps are superheated and overloaded as well as easily stuck. This may result in shorter life, frequent operation and soaring oil production cost. For this, Bohai Equipment Zhongcheng Machinery developed and designed deep and heavy oil well submersible electric pumps, developed high-power and high temperature resistant electric motors, and improved their cooling performance. The company also designed and applied full-flow-channel leaves resistant to heavy oil and support diverter cover technology, fulfilling long-lifetime production of deep and heavy oil well electric pumps. The successful development of such pumps fills the blank of domestic like products.

Key words: deep well, heavy oil, submersible electric pump, development and design

摘要： 塔里木油田具有油藏超深、原油超稠的特点,稠油在产出过程中有胶质沥青沉积和摩擦阻力较大的问题;加之井底温度高,常规潜油电泵机组电机过热、过载、易卡泵等,往往引起机组寿命短、频繁作业、采油成本居高不下。为此中国石油渤海装备制造有限公司中成机械制造公司开发设计了深井稠油潜油电泵机组,研制了大功率耐高温电机,电机散热性能改善;设计应用了宽流道抗稠油叶导轮、配套导流罩技术等,实现了深井稠油井电泵开采的长寿命运行。深井稠油潜油电泵机组的研制成功,填补了国内同类产品的空白。
