Description
Technical field
The invention belongs to the sucker rod and centralizer used in mechanical oil production technology field, more particularly, to sucker rod and help
The identification method of positive device.
Background technology
The turn(a)round of mechanical oil well sucker rod pumping, reaches the fatigue period of sucker rod（GenerallyCycle）For just
Often.Eccentric wear between sucker rod and oil pipe then causes that pump detection period is short, frequent maintenance, and the production cycle does not reach sucker rod fatigue period
It is the major reason for causing cost for oil production high.It is typically employed on oil pumping club shaft and the method for centralizer is installed to solve
This problem.In order to preferably solve this problem, occur in that many technologies for attempting to be identified to each sucker rod and
Method, such as by the method in chip card, magnetic stripe card, engraving Quick Response Code, bar code technology transplant to sucker rod.But decades
Come, succeeded without any one method.Reason is as follows：
(1) link is too many：New sucker rod go into the well completion go into operation at least to undergo lifting get on the bus, roping, unloading, put, measure,
Go into the well, touch pump, pressure testing, build the pressure, open and take out, normally run production etc..Any one link, which goes wrong, can all cause mark can not
Identification.
(2) stress is complicated：
A ground：Lift the bending that is squeezed to collide with, roping, which is jolted, collides with, unloading puts extruding by bending and collides with, falls, pounding, and goes into the well
When touch, fall, knocking well head, elevator well head etc..
In b wells：A pump bottom vibration is strong when touching pump, open body of rod when taking out rear upstroke be stretched elongation, down stroke when the body of rod
By bending compression, and from top to bottom because the power difference elongation suffered by every bar and the amount of compression are also different.Again due on sucker rod
Frequently commutation causes strong impact and vibrations for lower reciprocating motion.For outer implant necessarily with the body of rod because the difference of material is deposited
Cause to come off or damage in the nonsynchronous phenomenon of deformation.And come off and the part damaged also has the risk of holddown
（3）The high temperature of change, high pressure：
Oil well from well head to downhole temperature substantially according to 25 DEG C+geothermal gradient of surface temperature 3 DEG C/100 meters be stepped up.With
Exemplified by pump is deep 2500 meters：2500×3/100+25=100℃.Well head differs 75 DEG C with 2500 meters.With well depth different temperatures also not
Together, deflection is also just different.It is also what is be stepped up that mark, which bears pressure from well head to downhole well depth,.Still with 2500 meters of pump depths
Exemplified by：Liquid be water in the case of well head with differing 25MPa at 2500 meters, deflection also with regard to there is larger difference naturally
(3) bad working environments are superimposed：Any of the above bad working environments superposition.Even more cause currently without effective identification method
Major reason.
Existing method is：In oil well overhaul, the same or close sucker rod of hundreds of diameters, length, grade of steels and peace
The centralizer of top loading can attach the deposition dirt such as crude oil and wax when going out from well, lead to not see and measure centralizer clearly
Wear extent, is cleaned by environmental requirement not in scene.Oil pipe factory can only be pulled to（Specially to undergrounds such as oil pipe, sucker rods
Instrument carries out the place of HIGH TEMPERATURE PURGE）Carry out cleaning.When handling, cleaning terminate position of the rear every sucker rod in underground
Put, sequentially can not just confirm.Centralizer wear extent above is with well depth also just to not upper.
It is this oil recovery circle in the urgent need to once making the daily wear extent of each well section depth clear, in equal or similar bar
It is easy for making the time between overhauls(TBO) controllable under part, and can will to greatest extent controls effective identification method of cost to solve above-mentioned ask

The process and principle of identification method
Because the size for being available for wear volume of centralizer is the principal element of decision eccentric wear oil well overhaul cycle length.Centralizer
Just long, cost for oil production is just low the wear volume big then oil well overhaul cycle that is available for；Otherwise the time between overhauls(TBO) just short, cost for oil production just
It is high.The method in control oil well overhaul cycle is not difficult：Being ground for the centralizer on each sucker rod of well head is exactly measured out
Damage amount, calculates the volume that is worn of each centralizer, then divided by the production time, can thus show that each well section is ground daily
The volume of damage.The oil well overhaul phase number of days that being multiplied by with the volume that is worn of each well section daily to control just draws each well section
Required centralizer is available for wear volume.For example：The centralizer amount of being worn on a certain bar is 3mm, calculates this and helps
The volume that is worn of positive device is 6000mm3, and the production time is 600 days, then is easy to show that daily wear volume removes for 6000
With 600, such as will maintenance number of days control at 1500 days, then the centralizer is available for wear volume should be in 6 divided by 600 × 1500 ﹦
More than 15000mm3.Every sucker rod all represents the different depth in underground.Calculate the every of centralizer on every sucker rod
The minimum that it the volume that is worn also just has calculated the new centralizer gone into the well again by control number of days is available for wear volume.Flatly
Oil well decades even upper a century, once makes the daily wear extent of each well section depth clear, under equal or condition of similarity
It is easy for making the time between overhauls(TBO) controllable, and cost can be controlled to greatest extent.For many years such a Benefit but
Uncomplicated problem can not be but resolved all the time.Reason be in oil well overhaul, hundreds of diameters, length, grade of steel it is the same or
Close sucker rod and the centralizer being mounted above can attach the deposition dirt such as crude oil and wax when going out from well, lead to not
See clearly and measure centralizer wear extent, cleaned by environmental requirement not in scene.Oil pipe factory can only be pulled to（Specially to oil
The downhole tools such as pipe, sucker rod carry out the place of HIGH TEMPERATURE PURGE）Carry out cleaning.When handling, cleaning terminate latter every and taken out
Beam hanger underground position, sequentially can not just confirm.Centralizer wear extent above is with well depth also just to not upper.Allowed for this
It is essential that every sucker rod has a unique mark just to become.
