Development of a new heavy oil submersible submersible pump

In order to improve the effect of heavy oil production, the technical personnel of Dagang oil production plant adopt the amplification production pressure difference, increase the flow pressure of the wellbore, the submersible submersible pump to exploit heavy oil, and make a series of improvements on the process structure of the original submersible pump, widen the liquid channel, improve the temperature resistance level of the electric pump and cable, increase the power of the motor, and form the needle. A new heavy oil electric submersible pump for heavy oil production. The new heavy oil submersible submersible pump improves the liquid channel, widens the flow channel and reduces the flow resistance. The 50 cubic meter of the liquid submersible pump is changed from 4 square millimeter to 6 square millimeter. Due to the poor heat dissipation of oil, in order to ensure the normal operation and prolong the service life of the electric pump, the temperature rating of the motor and cable has been raised from 90 degrees Celsius to 150 degrees Celsius. The motor power is increased, the motor power of 50 cubic meters is changed from 37KWH to 46KWH, and the hot oil washing is carried out before the operation of the well, and the dead oil in the wellbore is washed out.
By December 21, 2017, the Dagang oil production plant improved the production process of thick oil well by organizing technical personnel to develop a new heavy oil submersible submersible pump suitable for the production of thick oil well, which increased 3171 tons of oil, which made the "short Shou well", which was not normally produced in the past, turned into a "longevity star well". The new type of heavy oil electric submersible pump has improved the production rate of oil wells and extended the service life of electric pumps, which has opened up a new way for heavy oil recovery.
