Description
Technical field:
The present invention relates to Non-Destructive Testing, a kind of non-contact type water soaked ultrasonic detection method and isolated plant that the oil field defect of sucker rod detects that be exclusively used in is provided especially.
Background technology:
Current, the oil recovery in each oil field all be unable to do without the application of sucker rod except that unloading well, usually sucker rod is worked under the effect of various load constantly all the year, always wants tired, and then generation fatigue crack, just begin stress after having crackle to produce and concentrate, lasting fatigue and stress are concentrated and also can be quickened crack propagation, finally cause rod broken, its consequence is to force oil well stopping production, well workover etc., causes a series of economic loss.Usually, the economic loss that once disconnected bar may cause is 12～200,000 yuan, and according to the statistics in present oil field, annual accident rate is interrupted bar and accounted for 15～35%, loss is surprising, is badly in need of a kind of method and apparatus that at the scene defect of sucker rod is detected for this reason.
The method of detection that can carry out fast automatic flaw detection in enormous quantities at present has: magnetic particle method and osmosis, eddy-current method, leakage method, ultrasonic method and X-radiographic real-time imaging method, wherein magnetic and osmosis running time only are fit to damage check on a small scale than length, X-radiographic real-time imaging method is more suitable at the volumetric defective, and two kinds of methods of eddy-current method and leakage method are modes comparatively common in the crack-detecting technology.At first, eddy-current method requires probe closely to contact with surface of the work during detecting a flaw with leakage method, had relatively high expectations to examining the surface of the work situation like this, and sucker rod produces the exhibiting high surface etch pit because of being in for a long time in the rugged surroundings, can't satisfy the closely needs of contact fully; Secondly, eddy-current method and leakage method are relatively more responsive to the gap of popping one's head in and examined between the workpiece, and the sucker rod surface usually is attached with certain thickness greasy dirt and long-pending wax, and they are huge to the flaw detection sensitivity influence of eddy-current method and leakage method; The 3rd, the existence of automatic rabbit requires must consider the major part avoiding device under the way of contact, but the workpiece of advancing fast in detecting operation the blind area can occur detecting again because dodging action, and a plurality of automatic rabbits that distributing usually on sucker rod have reduced detectable area greatly.Therefore, the free of discontinuities operation of detecting a flaw continuously be reached and traditional way of contact must be abandoned.
UT (Ultrasonic Testing) mainly is to travel to and fro between the definite defective of transit time of defective and the distance on surface by measuring-signal, the size and the orientation of defective determined in the amplitude by measuring echoed signal and the position of probe, and it has good Effect on Detecting for the defective of flat state (as crackle, interlayer, fold etc.).Compare with leakage method with eddy-current method, defect detection on ultrasonic basis has that directive property is good, high sensitivity, stable performance, be not subjected to the characteristics of electromagnetic interference (EMI), is being widely used aspect the weld metal crack flaw detection at present.Chinese patent 99232304.5 just provides a kind of " the ultrasonic automatic detection device of sucker rod ", its volume is little, be suitable for execute-in-place, but because it adopts the method that local water-filling is detected a flaw between probe and workpiece, the probe clamping device must be clamped on the sucker rod, thereby equally must consider the major part avoiding device, the detection blind area to occur be inevitable equally owing to dodge action.
Summary of the invention:
The purpose of this invention is to provide a kind of method and device thereof that defect of sucker rod detects that be exclusively used in, it can carry out the scene detection to coarse sucker rod, and omission do not occur.

The present invention is used for the non-contact type water soaked ultrasonic detection method that defect of sucker rod detects, and described ultrasonic probe occurs in pairs, becomes one 14 °～25 ° angles with the sucker rod axis direction, and directed in opposite.
The present invention is used for the non-contact type water soaked ultrasonic detection method that defect of sucker rod detects, and preferably adopts the line focus ultrasonic probe, focal line is focused on examined the near axis of sucker rod.
The present invention is used for the non-contact type water soaked ultrasonic detection method that defect of sucker rod detects, and described defect of sucker rod detects the body of rod of mainly being examined sucker rod two ends 80mm to first automatic rabbit in two ends.
The present invention also provides a kind of non-contact type water soaked supersonic detection device that defect of sucker rod detects that is used for that is exclusively used in above-mentioned method of detection, it is characterized in that: this device is made of probe travel mechanism, sucker rod supporting mechanism, flaw detection operating platform, crack monitoring warning and four parts of datalogger;
Described flaw detection operating platform comprises that a long water tank (1) and supports with base (6);
Described sucker rod supporting mechanism comprises 6～20 cover beam hanger supports (9), and at least two cover beam hanger supports (9) are fixed in the water tank (1), and an end is provided with beam hanger anchor clamps (2) that link to each other with gear train in the water tank (1);
Described probe travel mechanism is made of probe (8), U type probe bracket (3), walking guide rail (7); Walking guide rail (7) is parallel to sucker rod and axially is provided with; Open Side Down for probe bracket (3), and an end is installed probe (8) and level angle governor motion, and the other end slides at walking guide rail (7) upper edge water tank (1) length direction, has up-down adjustment mechanism (4), focus adjustment mechanism (5) on the probe bracket (3).
The present invention is used for the non-contact type water soaked supersonic detection device that defect of sucker rod detects, and one of beam hanger support (9) in the described two cover water tanks is arranged on the support guide (10) that is fixed on the water tank (1).
At first, disconnected bar sample electron microscope experiment result learns according to sucker rod, and the rod broken reason mainly is to originate from the surface to be mingled with fatigue crack with etch pit, and fatigue crack is all perpendicular to the bar axle, and the fracture propagation district is very level and smooth; Secondly, ultrasonic method only need need to fill propagation medium between probe and workpiece and need not pop one's head in and closely contact with workpiece.Therefore, ultrasonic method is more more suitable than other method to the detection of sucker rod fatigue crack, and probe does not directly contact with workpiece to dodging automatic rabbit possibility is provided, and the shaggy workpiece of suitable detection.
Since in the water velocity of sound be in the steel longitudinal wave velocity 1/4, sound wave during the incident steel workpiece, produces refraction back beam broadening from water, in order to improve detection sensitivity, often use focusing probe.In addition, for crack detection is carried out at each position of sucker rod, the flaw detection probe must axially be advanced along sucker rod, and might be distributed in circumferential optional position at the crackle at same position, then the flaw detection probe is examined sucker rod relatively must tangential motion, in order to reduce the detection blind area that sucker rod and probe are caused during relative motion, the present invention adopts the line focus probe, and according to the speed of related movement of focal line length adjustment probe holder and beam hanger.
Because ultrasonic method has the better detection effect to the plane crackle, simultaneously also because of the distribution characteristics of sucker rod fatigue crack perpendicular to the beam hanger axis, the present invention designed can adjusting angle probe holder, make probe and sucker rod axis direction have angle, thereby crackle is surveyed in the end corner reflection that utilizes fatigue crack to face ultrasonic shear waves.In addition, for fear of the shear crack omission, the present invention has also designed the hyperchannel array mode, and promptly ultrasonic probe occurs in pairs, and directed in opposite.Another the bidirectionally obliquely placed purpose of popping one's head in is to finish the flaw detection scanning of automatic rabbit root and near zone thereof, and this technology is compared with eddy-current method with traditional leakage method has absolute advantage.
For crack detection is carried out at each position of sucker rod, the flaw detection probe must axially be advanced along sucker rod; Secondly, the crackle at same position might be distributed in circumferential optional position, and then the flaw detection probe is examined sucker rod relatively must tangential motion.For this reason, the relative motion of workpiece and probe can have three kinds of modes, the fixation workpiece motion of promptly popping one's head in, probe movement and workpiece is fixed, probe and workpiece move simultaneously.Existing sucker rod defect-detecting equipment adopts the static probe mode usually, in order to reach the requirement of above-mentioned axial and circumferential motion, existing equipment have only allow examined sucker rod rotation on one side, an edge axis direction advances.Under traditional like this mode of motion, if workpiece has the unexpected variation (for example having annex) in cross section in length range, just must introduce avoiding device, and avoiding device must cause omission during finishing expansion and closed action, so, the mode that the present invention adopts probe and workpiece to move simultaneously, promptly axially and the tangential motion isolation technics: sucker rod is fixed on the support and around axis and rotates, and is fixed on the probe holder with the guide rail that is parallel to the sucker rod axis moving linearly that is as the criterion and pop one's head in.Axial and tangential motion isolation technics is the necessary means that realizes that automatic rabbit is dodged.
The present inventor is by discovering in a large number the fracture sucker rod, the load of sucker rod under in working order mainly is the alternate tension of axis direction, the fatigue crack that is produced under this loading is the transversal crack perpendicular to the sucker rod axis, and focus mostly near first automatic rabbit that begins from two ends and before the body of rod.Therefore, the present invention proposes and need not detect a flaw to sucker rod integral body, and only detection is focused near first automatic rabbit in two ends and the body of rod before, thus greatly reduce the entire length of sucker rod fatigue crack failure detector, make the scene detection of sucker rod possess feasibility.
