ELECTRIC SUBMERSIBLE PUMP (ESP) SEAL UNIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18604755 titled 'ELECTRIC SUBMERSIBLE PUMP (ESP) SEAL UNIT
The abstract describes an electric submersible pump (ESP) system that includes a pump and a motor connected to drive the pump in a wellbore to pump fluid into production tubing. The motor produces heat while operating, and a seal unit is connected between the motor and the pump to contain oil for lubrication and to manage heat exchange.
- The ESP system consists of a pump and a motor connected to drive the pump in a wellbore.
- The motor generates heat during operation, which is managed by a seal unit connected between the motor and the pump.
- The seal unit contains oil for motor lubrication and receives heat from the motor during operation.
- The seal unit is designed with a structure to reduce heat loss after the motor stops running, minimizing oil exchange with the wellbore and preventing the influx of wellbore fluids into the seal unit.
Potential Applications: - Oil and gas industry for wellbore fluid pumping - Submersible pump systems for various industrial applications
Problems Solved: - Heat management in ESP systems - Preventing oil and wellbore fluid exchange
Benefits: - Efficient operation of ESP systems - Extended lifespan of motor and pump components
Commercial Applications: - Oil and gas production - Industrial fluid pumping systems
Questions about the technology: 1. How does the seal unit in the ESP system prevent heat loss and oil exchange? 2. What are the key advantages of using an ESP system in wellbore fluid pumping operations?
Frequently Updated Research: - Ongoing studies on improving heat management in ESP systems for increased efficiency and longevity.
Original Abstract Submitted
An electric submersible pump (ESP) system is described herein. The ESP system includes a pump and a motor connected to drive the pump. The pump and motor are disposed to pump fluid into production tubing in a wellbore. The motor produces heat when operating. The wellbore contains wellbore fluids. A seal unit is connected between the motor and the pump. The seal unit contains oil to lubricate the motor. Further, the seal unit receives heat from the motor when the motor is running. The seal unit contains a structure to reduce loss of heat after the motor stops running to reduce an exchange of oil from the seal unit to the wellbore and to reduce an exchange of wellbore fluids from the wellbore to the seal unit.
