Description
Technical field
The present invention relates to a kind of petroleum drill strings to damage wellhead detecting device, especially a kind of based on Magnetic memory testing effect
Drill string damages integrated wellhead detecting device, belongs to field of non destructive testing.
Background technique
Petroleum drilling base for post sheet is made of kelly bar, drilling rod, drill collar and connector.Petroleum drill string will be born in drillng operation
A variety of stress such as drawing, torsion, press-bending, are also washed away and are corroded by mud, service condition is very harsh.So harsh clothes
Labour condition easily makes drill string generate fatigue crack, etch pit etc. in addition prolonged drilling well is on active service；If drill string originally there is material
Expect that defect, these defects may become the generation and expansion of tired source and the crackle that accelerates fatigue, or even can be due to these defects
Presence cause drill string static strength to be substantially reduced, be just broken in use if encountering accidentally strong load, accident oil supply occur
Bring economic loss in field.Drilling string failure crash analysis for many years and drill string scene flaw detection confirms that drill string itself is past before going into the well
Toward dangerous property defect.
The problem of for very good solution drilling string failure, need to find and find it is various can cause drilling tool failure because
Element.But failure cause could be determined after physico-chemical analysis completely by only dissect etc. to drilling tool at present, and can not will be each
Root drilling tool is all dissected, therefore typically now uses lossless detection method, and finding before drilling tool failure may cause failure
Various major defects are come the generation prevented accident.And existing conventional non-destructive testing technology means are in early diagnosis tool joint spiral shell
Line position stress exists obvious insufficient in terms of concentrating abnormal and micro-crack.As: (1) good measured surface ultrasound examination needed for
Contact conditions and couplant condition are difficult to realize in screw thread position, cause detection effect very undesirable and not applicable well head
The detection of not shackle drilling tool thread；(2) magnetic leakage detection technology needs detection probe and measured surface close contact, for well head screw thread
Detection in the case of not shackle can not be realized；(3) in existing nondestructive stress measurement detection method, x-ray diffraction technology
Penetration depth only have tens microns, it is difficult to touch thread root, magnetosonic transmitting, Barkhausen noise and magnetic survey stress mornitoring method
It is both needed to electromagnetic excitation condition (coil), excitation coil and detection probe composite structure are bigger than normal, can not differentiate variable diameter point and root
The stress state in portion, it is difficult to application is obtained in thread measurement.It is existing it was verified that existing nondestructive testing technique (such as whirlpool
Stream, ultrasound, X-ray etc.), the gross imperfection occurred for detection is more effective, requires not shackle for well head thread measurement
In the case of detection can not achieve.
The basic principle of magnetic memory detection technology is: micro-crack meeting of the ferromagnetic metal workpiece due to fatigue and creep generation
There is stress concentration in fault location, since there are magneto-mechanical effects for ferromagnetic metal workpiece, therefore the Distribution of Magnetic Field on its surface with
Workpiece stress load has certain corresponding relationship, therefore can be by detecting the Distribution of Magnetic Field situation of workpiece surface indirectly to workpiece
Defect and stress concentration region diagnosed, while metal magnetic memory sensor has biggish sensitivity, for well head drilling tool spiral shell
Line can penetrate detection of the tool joint outer wall realization to drilling tool thread site of engagement when engaging, a kind of based on Magnetic Memory to develop
The drilling tool damage wellhead detecting device of effect provides solid foundation.
