Oil well pipe wall thickness logging data interpretation and corrosion defect intelligent judgment method

The invention discloses an oil well pipe wall thickness logging data interpretation and corrosion defect intelligent judgment method, which comprises the following steps of S1, collecting wall thickness logging data of a target oil well pipe, and performing integration and numbering preprocessing on the wall thickness logging data; s2, judging whether the wall thickness data is smaller than the standard wall thickness value of the target oil well pipe one by one in the well depth and circumferential direction, and marking wall thickness reduction data points; s3, combining the adjacent wall thickness reduction data points to obtain a corrosion defect part, identifying the corrosion defect form of the corrosion defect part, and dividing the type of the corrosion defect according to the corrosion defect form; and S4, counting the number of corrosion defects, the width and depth of a defect opening and the distribution characteristics of the corrosion defect form along the well depth, and drawing a defect distri
