What is the method of centralizer eccentric wear?

The centralizer has the function of centralizing tool string,which can improve the logging effect of centralized logging tool.It can also prevent the instrument from hitting the borehole wall,reduce the interference to the acoustic logging instrument,and prolong the service life of the instrument.Centralizer is a kind of oil production tool used in pumping well.It is a new product to improve pump efficiency.It adopts automatic opening and closing structure of slide valve and is connected with sucker rod.As the sucker rod drops,the slide valve rises and opens.As the sucker rod rises,the slide valve descends,closing the oil path on the centralizer.Therefore,the section extraction column can reduce the load of the sucker rod and the section pump,reduce the leakage of the pump and the elastic elongation deformation of the sucker rod leakage and stroke loss,so as to improve the effective stroke of the pump,increase the filling amount of the pump cylinder and improve the efficiency of the pump.
