Abstract
This inventive technology is that all kinds of grooves, which have different width, different depth, different space and different shape, are provided on the coupling faces of oil pipe and sucker rod in the oil field, when magnetic material approaches the coupling faces of oil pipe, the magnetic field formed after the faces is magnetized can be changed owing to the grooves, the magnetic signal is converted into the electrical signal via the sensing element and the signal process unit and the change of magnetic field is identified, the configuration rule of the width of grooves, depth of grooves, space of grooves, shape of grooves or the like can be identified through the change of magnetic field so that the informations which are given by the configuration rule of gooves, such as the class of oil pipe and sucker rod, the specification of oil pipe and sucker rod, manufacturer of oil pipe and sucker rod, the use time of oil pipe and sucker rod, and the like, can be identified, accordingly the marking, identification and automatic management of oil pipe and sucker rod in the oil field, can be realized. The remark of grooves is not affected by the temperature, pressure, electromagnetic field, corrosion of oil-gas mixture, pollution, bumping, weather, ect., thus the remark on the oil pipe and sucker rod has long service life and is suitable for the marking and identification of oil pipe and sucker rod.
Description
Technical field
The invention belongs to the magnetic induction technical field, relate to magnetic-field measurement technology and magnetoelectricity switch technology.
Technical background
Power tools such as the various oil pipes in oil well down-hole, sucker rod, because they invade bubble for a long time in having the oil gas water mixed liquid of severe corrosive, existing being marked on the power tools such as these down-hole metal tubes, bar is difficult to long-time reservation, be corroded soon, add that black greasy filth pollutes, and is difficult to identification; If be implanted into chip at power tool bodies such as these down-hole metal tubes, bars, owing to be subjected to the shielding effect of metallic walls, REID also is difficult to realize; Operation is extensive during operation, often and other metal bump, add sandblast in cleaning, the maintenance process, thermal treatment etc., make the magnetic card recognition technology also inapplicable.For power tools such as the widely used various oil pipes in oil well down-hole, sucker rods, also there are not applicable mark and recognition technology at present both at home and abroad, can't carry out the robotization tracing management to the recover the oil power tool such as various oil pipes, sucker rod of usefulness of oil field.The present invention is applicable to the mark and the identification of power tools such as the various oil pipes in oil well down-hole, sucker rod, helps making the oil field by reliable mark and automatic identification technology power tools such as the widely used various oil pipes of oil producing operation, sucker rod to be realized the robotization scientific management.
Summary of the invention
The objective of the invention is to be immersed in work characteristics in the oil gas water mixed liquid with severe corrosive for a long time at borehole operation instruments such as widely used various oil pipes, sucker rod in the oil well operation process, and the characteristics of link such as operation process, the course of work, maintenance process, cleaning process and requirement and propose a kind of electromagnetic type slotted weight marking and recognition technology.
Technical scheme of the present invention is: at oil pipe, leave various grooves on the sucker-rod coupling end face, when magnetic material when the tubing joint end face, the magnetic field that the existence of groove forms end face magnetization back changes, the width of groove, the degree of depth, at interval, shape is (as shown in Figure 1) not simultaneously, changes of magnetic field difference (as shown in Figure 2), groove depth changes of magnetic field peak value is big, the shallow changes of magnetic field peak value of groove is little, the groove width changes of magnetic field is wide, the magnetic field that has changed converts magnetic signal to electric signal by sensing element, by signal processing unit the variation in magnetic field is discerned, identify the width of groove by the variation in magnetic field, the degree of depth, at interval, the rule of arranging such as shape, the rule difference of arranging according to groove, give its manufacturer, specification, information such as service time, this width according to groove, the degree of depth, at interval, the form that differences such as shape are encoded is called slotted weight, thereby identify the implication that slotted weight itself is given by the identification slotted weight rule of arranging, determine various oil pipes, the kind of sucker rod, specification, manufacturer, information such as service time realize oil pipeline, the mark of sucker rod, identification and automatic management.
The present invention has following advantage:
On oil pipe, the sucker-rod coupling end face slotted weight mark be not subjected to temperature, pressure, electromagnetic field, gas-oil mixture corrosion (oil pipe, sucker rod itself have antiseptic power), pollute, collide with, the influence of external condition such as weather, be marked at long service life on oil pipe, the sucker rod body, the magneto-electric recognition technology is not influenced by marking contaminated, bright and dark light, physical environment etc., is suitable for the oil pipe in the oil recovery process of oil field, the mark and the identification of sucker rod.

Embodiment
(1) slotted weight form and coding rule
At oil pipe, the sucker-rod coupling end face start mark that to open a groove that 5mm is dark, 2mm is wide be slotted weight, other slotted weight marks adopt marker spacing differences, width difference, the different expressions of the degree of depth.What table 1 was listed is that groove depth is 7mm, 5mm, 3mm, and groove width is 2mm, 4mm, and groove is spaced apart the coded identification setting that 2mm, 4mm are example.According to assembled arrangement, can compile out following 43 slotted weight: #A; #B; #C; #D; #E; #F; #AB; #AC; #AD; #AE; #AF; #BC; #BD; #BE; #BF; #CD; #CE; #CF; #DE; #DF; #ABC; #ABD; #ABE; #ABF; #ACD; #ACE; #ACF; #ADE; #ADF; #AEF; #ABCD; #ABCE; #ABCF; #ABDE; #ABDF; #ABEF; #ACDE; #ACDF; #ADEF; #ABCDE; #ABCDF; #ACDEF; #ABCDEF.According to realizing that needs can increase groove depth, groove width, groove quantity increase slotted weight permutation and combination number at interval.Represent the information such as kind, specification, manufacturer, service time of oil pipe, sucker rod with slotted weight, realize mark and identification oil pipe, sucker rod.
