Changing, sucker rod pumping system working environment progressively deteriorates, and exacerbates side-abrasion of rod string, and High water cut is rod pumped well tube rod
There is eccentric wear, the basic reason of corrosion.According to sucker rod pump side-abrasion of rod string present situation, scene is typically taked following anti-
Eccentric wear measure: mainly use the instrument such as oil pumping rod centering device, abrasion resistance pair to draw, its basic ideas are not allow pipe
Bar contacts.Using oil pumping rod centering device weak effect, the cycle is short, increases polished rod load, there is also mill itself
Damage problem；Use anti-wear pair for sucker rods subject matter to be centralizer body and stuck phenomenon easily occurs in the body of rod, stuck
After be equivalent to common bias wearing joint hoop, cost is high, affects field popularization application.Wear-resistant tube rod is to a certain extent
Can improve the wear resistence of tube rod, reduce wear rate, pump detection period has certain prolongation, but itself processes work
Skill is complicated, and cost is high, and there is spot corrosion phenomenon.Currently also utilize hollow stem endoporus as well liquid passage
, but annular space is slowly enriched with only with the oil of well liquid, or oiling before completion, it is impossible to according to need
Will oiling at any time, and can not deeply take out.In a word, high water-containing rod pumped well tube rod eccentric wear-proof process general thought is also
Rest in the aspect of righting, wear-resistant, anti-attrition, it is impossible to fundamentally solve the eccentric wear of high water-containing rod pumped well
Problem.
