The apparatus comprises a flow signal processing device, a flow measuring device, a motor, a motor control device, an apparatus supporting and limiting device and a regulating device which are arranged in sequence, wherein the motor and the motor control device are respectively connected with the apparatus supporting and limiting device and the regulating device. The apparatus has the advantage that the real time test and regulation of the injection flow rate can be realized.
Description
Technical field
The utility model relates to the downhole instrument of a kind of measurement and regulated fluid flow, relates in particular to a kind of concentric intelligent water distribution measurement and adjustment downhole instrument that is used for used for water injection wells in oil fields.
Background technology
At present, what each elephant of China adopted when regulating concentric injection allocation water injection well water injection rate is traditional adjusting technology, promptly can only be on ground according to the required water injection rate of each layer, water injection pressure, select for use a kind of blanking plug water nozzle of permanent opening to drop in the well by experience, and then the throwing flow meter, whether the water injection rate on measurement target stratum meets the water injection technology requirement; If do not reach requirement, then need salvage water nozzle changes, again change a different big or small blanking plug water nozzles inputs down-hole according to flow of measuring and empirical value, and then flow meter rendered to destination layer inspection, repeatable operation like this, make the destination layer water injection rate reach predetermined water injection rate, finish the allotment of this layer.General water injection well all is the multilayer water filling, must descend the allotment of one deck water injection rate after one deck water filling allotment is finished, and method also is will be through repeatable operation repeatedly as mentioned above.The water yield of regulating individual layer generally needs 6～8 hours, and a bite well is by 4 layers of calculation, and adding the upslide instrument so and dragging for the working time that the instrument time regulates a bite well is 5～8 days, and during working expenditure, effort, difficulty and intensity are all bigger, are difficult to reach desirable requirement.
Cause an important reasons of this traditional handicraft to be: existing concentric water distribution measurement and adjustment downhole instrument all can not be realized surveying and transfer downhole instrument that the injection flow of concentric injection well downhole flow regulator down-hole water nozzle is surveyed accent in real time, and promptly existing concentric injection well downhole flow regulator water nozzle can not carry out on-line continuous to be regulated.
The utility model content
The technical problem that the utility model solves provides a kind of concentric intelligent water distribution measurement and adjustment downhole instrument, and it has solved, and concentric injection well downhole flow regulator water nozzle can not carry out the technical problem that on-line continuous is regulated in the prior art.
Technical solution of the present utility model is:
A kind of concentric intelligent water distribution measurement and adjustment downhole instrument, its special character is:
Comprise the flow signal treating apparatus that sets gradually, flow measurement device, motor and motor control assembly, instrument supporting and limiting device and adjusting device, wherein motor is connected respectively with instrument supporting and limiting device, adjusting device with motor control assembly.
Above-mentioned adjusting device is made up of the regulating arm of power transmission shaft and automatically retractable.
Above-mentioned flow measurement device is a ultrasonic flowmeter.
The utlity model has following advantage:
But 1, instrument supporting and limiting device VO and withdrawal.Can add manual intervention at any time, can control instrument support and the opening and regaining of stopping means.Instrument the down-hole at any time can more than carry also and can transfer, flexible operation, efficient improves.Once go into the well and just can finish whole measurements and water filling allotment work, thereby can shorten the working time of surveying into a bite well, will foreshorten to original 1/4～1/8 duty cycle.
2, the design individual motor is come the rectilinear motion of control instrument supporting and limiting device 4 and rotatablely moving of adjusting device 5 respectively in motor and the motor control assembly, make with the electronic water nozzle aperture size of adjusting device 5 couplings and can regulate arbitrarily, adjusting can main story, also can reverse, easy to adjust, the adjusting time is short.
3, adopt the ultrasonic measurement meter, improved the flow measurement success rate, the certainty of measurement height, it is little to play the survey discharge capacity.And very little to the destruction in flow field, down-hole when measuring flow, flow measurements approaches actual water injection manifold value.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1-flow signal treating apparatus, the 2-flow measurement device, 3-motor and motor control assembly, the 4-instrument supports and stopping means, the 5-adjusting device.
The specific embodiment
Referring to Fig. 1, a kind of concentric intelligent water distribution measurement and adjustment downhole instrument, comprise flow signal treating apparatus 1, the lower end of flow signal treating apparatus 1 is provided with flow measurement device 2, motor and motor control assembly 3, instrument supporting and limiting device 4 and adjusting device 5 successively, motor is connected with instrument supporting and limiting device 4 with motor control assembly 3 lower ends and is connected with adjusting device 5 simultaneously, make motor and electric machine control system drive instrument supporting and limiting device 4 and adjusting device 5 simultaneously, flow measurement device 2 is a ultrasonic flowmeter.
Flow signal treating apparatus 1 contains the circuit unit that the flow value that flow measurement device 2 is recorded carries out coding transmission, and its effect is the flow value that flow measurement device 2 records is encoded and to be transferred to ground controller.Motor control assembly 3 is the circuit units that direct current generator carried out forward and backward control and protection, and its effect is according to the control command that controller is sent the direct current supply of motor to be switched, to realize the forward and backward control of motor.Instrument supporting and limiting device 4 has two metal parts of certain intensity and given shape, is used for measurement and adjustment instrument device body supports and is fixed to concentric water distribution seating nipple.Adjusting device 5 is made up of the regulating arm of power transmission shaft and automatically retractable.
The utility model can use a motor, and at this moment motor and motor control assembly 3 should satisfy instrument supporting and limiting device 4 and outwards open, and realizes the instrument support limit; Satisfy again in adjusting device 5 with after the down-hole water nozzle cooperates, can realize screwing and unscrewing the down-hole water nozzle.Motor and motor control assembly 3 can realize that the ground handling personnel control this concentric intelligent water distribution measurement and adjustment downhole instrument.
During work, the utility model is transferred to the aspect that the down-hole needs measurement of discharge, thereby drive instrument supporting and limiting device 4 by motor and motor control assembly 3 and outwards open the support and the location of realizing concentric intelligent water distribution measurement and adjustment downhole instrument, outwards open rear motor and motor control assembly 3 when instrument supporting and limiting device 4 and just lost the control of opening instrument supporting and limiting device 4, this rear motor and motor control assembly 3 just can only control to adjust the positive and negative rotation of device 5, electronic water nozzle is realized screwing and unscrewing, and flow can increase when screwing electronic water nozzle; Flow can reduce when unscrewing electronic water nozzle, is measured by the flow of 2 pairs of these aspects of flow measurement device simultaneously.The utility model has been realized the automatic survey of downhole flow is transferred by the way.
