Analysis and Countermeasures on the Efficiency of the Pumping Wells System in the Old Oil-field

Abstract: In China, some old oil fields into the late stage of development, the wellbore fluid become complexity, and the production and the pump efficiency gradually decline, which lead to an increase in production costs. According to the statistics, the efficiency of 36.7% of the total wells are lower than 30%, By analyzing the main reason for the low efficiency of the pump and combined the status of oil well production, statistical analysis on the impact of system efficiency under different working conditions and est… Show more
