Abstract: Few Heavy oil fields like Shengli oil field were found in succession in the early 60s of 20th century. In order to effec
tively develop this kind of heavy density and high viscosity oilfield by using producing casing with diameter of 139.7 mm, research on
hydraulic piston pump technology was officially launched in Shengli oilfield by ex-petroleum Ministry. The water was just starting to
yield in middle- high permeability oilfield which original operated in 60s in the 20th century, and for meeting the requirement of liquid
lifting and deep pumping in 70 ar ificial lifting production measures were progressed under the condition of 139.7 mm production cas
ing, besides, the hydraulic piston pump technology was studied, improved and integrated by Petroleum Ministry, and opened cycle and
power fluid with crude oil were adopted to simplified the process. The state of water replaced by oil was occurred with the increasing of
water content, which results in the issues that the amount of power fluid was excessive and the surface flow process system continued
to extend which was not considered economically feasible. So the hydraulic piston pump tcchnology was quitted the historical stage in
China because of above problems in lately 20th century. In this paper through practical analysis we proved that the reason for disuse of
hydraulic piston pump technology not was the immature of the technique but the incorrect operating condition and improper direction
of rescarch. At present, any kind of artificial lifting techniques has its own characteristics and can not replace by each other. In order to
improve the performance of manual lifting series, this paper has proposed to re-study the hydraulic piston pump and correctly understand
the usage conditions of piston pump to restore the key role of hydraulic pump in artificial lifting technology
Key words: hydraulic piston pump; power fluid; opened cycle; closed cycle
