Description
Technical field
The present invention relates to a kind of defect quantitative nondestructive inspecting equipment for oil casing.
Background technology
The methods such as existing tubing and casing defect ray detection, Ultrasonic Detection, Magnetic testing, Liquid penetrant testing, EDDY CURRENT can realize the qualitative detection of excessive defect, but can not determine surface or inherent vice size measures, data cannot be provided for the calculating of the tubing and casing safety reliability in use, the reliability design of tubing and casing tubing string can not be applicable to, need the reliability design that a kind of lossless detection method that quantitatively can detect flaw size is tubing string to provide basic data.The quantitative detecting method that a kind of oil annular tube defect quantitative non-destructive control probe of the present invention can be defect provides appointed condition.
Electromagnetic supersonic flaw detecting is an emerging Dynamic Non-Destruction Measurement.Have without the need to couplant due to electromagnetic supersonic flaw detecting and be convenient to features such as exciting various mode ultrasonic, all having wide practical use at metallurgy, railway, oil, electric power, chemical industry, nuclear energy and even military industry field, more and more cause the concern of people.It is particularly suitable for using the place of couplant to carry out carrying out flaw detection.Alternating current field measurement technology (ACFM) detects for fatigue crack and welded structure and has for a long time, alternatively there has also been at marine industry now and applies widely.Because this technology is electromagnetic method, avoid thorough cleaning requirement, have many facilities than classic method, particularly do not need to carry out visual inspection to detection zone, whole testing result records can be obtained for examination and alignment purpose, to provide higher reliability, reduce manual operation and rely on.Because this technology provides the information that defect length, depth and place etc. are a large amount of, these results detected can be used as historgraphic data recording in computer, trace to the source and audit for later data.
Summary of the invention
The object of this invention is to provide a kind of defect quantitative nondestructive inspecting equipment for oil casing, the quantitative detecting method that can be defect provides appointed condition.
Defect quantitative nondestructive inspecting equipment for oil casing of the present invention is made up of probe, probe frame, signal wireless transmission and signal amplifying system, ball, stator, mover, support and roller;
The drum type brake stator being wound around copper cash is fixed on support, three balls are fixed on stator inner surface, the drum type brake mover being wound around copper cash is placed on ball, mover connects as one with probe frame, 2-4 probe is circumferentially evenly arranged on probe frame inside surface, signal wireless transmission and signal amplifying system and battery are arranged on probe frame outside surface, and are connected with probe; Roller is placed in support both sides.
Probe is by ac-excited signal coil, and strong magnetoelectricity magnet and magnetic susceptibility original paper are formed, ac-excited signal coil is a cubic coils, strong magnetoelectricity magnet is made up of four Z-direction periphery strong magnetoelectricity magnet and the strong magnetoelectricity magnet in Z-direction center, four Z-direction periphery strong magnetoelectricity magnet are evenly arranged in ac-excited signal coil 1 periphery, Z-direction center strong magnetoelectricity magnet is positioned at ac-excited signal coil center, contrary with Z-direction periphery strong magnetoelectricity magnet direction, magnetic susceptibility original paper is by the responsive original paper of Z-direction magnetic field magnetic, the responsive original paper of X-direction magnetic field magnetic and the responsive original paper of Y-direction magnetic field magnetic are formed, the responsive original paper of Z-direction magnetic field magnetic is made up of four magnetic susceptibility original papers, be evenly arranged between Z-direction center strong magnetoelectricity magnet and the strong magnetoelectricity magnet of Z-direction periphery, the responsive original paper of X-direction magnetic field magnetic is made up of two magnetic susceptibility original papers, be arranged between Z-direction center strong magnetoelectricity magnet and the strong magnetoelectricity magnet of former and later two Z-direction peripheries, the responsive original paper of Y-direction magnetic field magnetic is made up of two magnetic susceptibility original papers, be arranged between Z-direction center strong magnetoelectricity magnet and the strong magnetoelectricity magnet of two, left and right Z-direction periphery.
Determine wire circle according to detector tube body wall is thick, at coil mid-wrap electromagnet, electromagnet is also settled in the centre at four edges, limit, and X, Y, Z magnetic susceptibility original paper is placed at hub of a spool position respectively.Be connected with signal handling equipment with high-frequency ac electric signal source, coil inspires ac signal at tube surfaces, acts in body produce ultrasonic propagation with the magnetic line of force.When defectiveness, the field signal intensity that X, Y, Z-direction magnetic susceptibility original paper detect changes, and now starts defect to be detected.When the magnetic field intensity detected when popping one's head in is recovered normal, defect terminates.Set up probe and axially change the funtcional relationship of time with circumferential translational speed and signal intensity at tube surfaces, defect size can be gone out according to probe signal Strength co-mputation.
Because this technology is electromagnetic method, avoid thorough cleaning requirement, have many facilities than classic method, particularly do not need to carry out visual inspection to detection zone, whole testing result records can be obtained for examination and alignment purpose, to provide higher reliability, reduce manual operation and rely on.Because this technology provides the information that defect length, depth and place etc. are a large amount of, these results detected can be used as historgraphic data recording in computer, trace to the source and audit for later data.
