How to avoid uneven wear and corrosion on the inner wall of oil well pipes?
Thread Content
As mentioned above, in a certain oil field, the pump pistons began to abrade against the inner wall of the oil well pipes after just over a year of use, resulting in the premature failure of those pipes. There are two reasons for eccentric wear: one is the use of oil containing high levels of corrosive substances such as hydrogen sulfide, and the other is friction against the well wall during the movement of the pump plunger. We usually call it abrasion. Take a look to see if there are any good protection methods to avoid uneven wear.
Only by adjusting the position can abrasion be solved at its root, right?
During oil production, there are inclined wells in the tubing strings, and it is indeed challenging to keep these wells aligned in order to prevent uneven wear.
