Investigating the rodless technology of oil and gas fluid production in deviated wells

Abstract

The article presents the results of field trials of an experimental plunger submersible pumping unit on a directional well at the Romashkino oil field. The authors compare the performance parameters (electricity consumption and torque developed by the drive during steady-state operation) of the rodless oil production technology to the use of rod pump units and traditional pumping units.It is dealt with the inclinometric parameters of the wellbore, certain characteristics of energy consumption, as well as data on the torque developed during operation on the drive shaft of an experimental plunger submersible pumping unit obtained during field trials.The authors of the article considered the experimental results obtained and came to the conclusion that the new rodless technology of oil production fundamentally proves its performance under operating conditions in a directional well, and the energy indicators confirm the efficiency and significantly exceed installations based on rod pumps.
