Open publisher page 0 citations

Abstract

To sucker-rod pumping well,defect of sucker rod is one of main factors which inflence production of pumping well.On the basis of electromagnetic induction eddy principle,the sucker rod wellhead nondestructive inspection unit is developed.It solves the defect detection problem to sucker rod during production of oil well,thus,the sucker rod existing defect is eliminated through selection. Through field application in 315 wells,the unit can ensure the quality of running sucker rod and prolong the service life of sucker rod.$$$$
