Background technology
Operating Pressure refers in the case where well head has pressure, carries out a kind of advanced operating type of lower oil tube.Its energy
Enough effectively protection strata pressures, reduce operating cost, environmental protection.Rise, during lower oil pipe, it is necessary to which two groups of preventers are handed over
For the upper and lower part mineshaft annulus of sealing tubing coupling, to tubing coupling being played out or being transferred in order well by way of falling
In cylinder.
When tubing coupling is in the closing pit shaft of preventer bottom, operating personnel can not be from known outside tubing coupling
Particular location, if when tubing coupling passes through preventer, fail to open ram block or glue core in time, tubing coupling will
Meeting direct collision ram block or glue core, seal failure is caused, preventer damage, gas blowout accident will be caused when serious.Therefore,
, it is necessary to a kind of device that can accurately detect tubing coupling particular location in the wellbore during Operating Pressure.Device exports
Necessary alarm signal or control signal, make ram preventer by rise, the order of lower oil pipe opens or closes ram seal pair, make
Tubing coupling safety well head, avoids the generation of well head and underground work accident.In the intelligence of core link lifting Operating Pressure
Energyization, automaticity, improve the efficiency of Operating Pressure.
The present invention devises a kind of box cupling detection device of the vertically and horizontally Magnetic Flux Leakage Inspecting based on magnetic field.The equipment adapts to any
The workplace of wellbore pressure, do not limited by pit shaft internal high pressure.The collar location of oil pipe can be detected in real time in operation field
Situation, timely output control signal and sound and light alarm signal.
The content of the invention
The purpose of the present invention is to rise, in lower Tubing During Running, detecting tubing coupling position in real time.Detected by specific magnetic fields
Method and calculation, accurate modeling analysis tubing coupling simultaneously determine positional information.For site operation personnel and Automated condtrol
System provides reliable signal source, to reach guarantee job safety, improves operating rate, ensures job safety purpose.
The present invention is by high pressure pipe nipple, coil assembly, sensor unit, shield and control box bracket, sound and light alarm assembly, electricity
Source assembly composition, it is characterized in that：The processing and manufacturing of high pressure pipe nipple meets oil gas field Specification, and increases on body construction
Added excitation wire ring recess, detection line ring recess and sensor mounting hole, body can in 20000psi operational pressure reliable work
Make.
Coil assembly of the present invention is made up of magnet exciting coil and detection coil.Magnet exciting coil passes through ring channel structures uniform winding
On high pressure pipe nipple, detection coil is fixed on the inside of magnet exciting coil by the way of the combination of multigroup coil by special construction.Excitation
Coil produces quantitative field by constant current source power supply.When tubing coupling passes through detection means, will be produced inside detection coil
Induced electromotive force.In calculating using the amplitude of induced electromotive force as reference value obtain oil pipe velocity component, extract signal when
Between the component trigger signal and auxiliary judgment foundation that are detected as box cupling.
Inventive sensor assembly is made up of four groups of spy boots, and every group, comprising boots shell, magnetic susceptibility array is visited, is visited boots and be fixed on
On high pressure pipe nipple, two groups are often held, totally four groups.Integrated multipath magnetic susceptibility array in boots is visited, the multichannel integrated in magnetic susceptibility array passes
Sensor can extract the different directions magnetic field signal of same position, the standard signal judged after filtering interference signals as box cupling.Mark
Calibration signal is special by the fluctuation in signal through with the velocity component of detection coil and when playing machine after the initial calibration value amendment of the signal
Sign contrasts with box cupling model, and the amplitude phase relation of fitting data and model, contrast draws the similarity of box cupling and then determination connects
Bind round position.Not using the induced electromotive force of detection coil as detection approach in detection process, and it is empty by magnetic susceptibility array detection
Between the mode of changes of magnetic field detect tubing coupling.
The present invention produces positive effect
The present invention is detected using non-contact magnetic method, is not only restricted to the size of well head pressure, and application field is extensive.Removing oil
Guan Shi, tubing coupling position can be detected in real time.The invention is different from the modes such as traditional encoder measurement and single Coil Detector,
And the method for using magnetic susceptibility array detection space stray field.Encoder measurement tubing length calculates the method and list of collar location
One Coil Detector etc., due to encoder guide wheel skids, oil pipe is static in cumulative errors and single Coil Detector, speed change, commutation etc.
Factor produce maloperation and can not practical application.The present invention is not by oil pipe is static, speed change, commutation etc. influence, and detection is as non-
Contact detection in real time, no guide wheel skids and the factor such as cumulative errors influences, and can determine whether the oil pipe direction of motion for operating personnel and
Control system provides more reliable signal and more information.
