Top Anchored Stationary Barrel Downhole Pumps For Sandy Wells
Top anchored downhole Pump description:
A downhole Sucker Rod Pump is used on onshore sites to create a mechanical lifting motion. This motion is created by a series of valves, plungers, rod strings and rods that are assembled together as a pumping system.
There are two different barrels and plungers in series connection
pump. According to the theory of hydraulic feedback, during the
down stroke, a downward force is formed to overcome the friction
between the viscous crude and the sucker rod, thus improving the
load condition on the sucker rod and decreasing and eliminating the
disconnection and break of
the sucker rod. The pump applies to the wells of oil viscosity less
than 4,000mPa*s(50℃),the wells with thin oil and the viscous
oil wells without thermal recovery conditions.
