Application
Heavey production oil
Low production wells due to low capital&running cost
Wells with varying in follows
Wells with high water cut
Dewatering of gas wells
pumping principle
The subsurface pump consists of rotating part called rotor and fixed part called stator when the rotator is placed inside stator a series of sealed cavities are formed
as the rotor turns these cavities progress from the suction end to the discharge end positively transporting the well fluid through the pump&up the tubing string to the surface
Pcp classification
Top drive
Similar to beam pump
Surface equipment consists of a motor, gear reducer, drive head
Subsurface equipment consist of pcp&rotor and stator
in between sucker rod&polished rod exist
نتيجه للدوران المستمر لل rod داخل البئر فاذا كان هناك تلامس كبير يحدث تاكل بسرعه كبيره
