Description
Technical field
The utility model relates to a kind of downhole instrument of regulating and measuring fluid flow that is widely used in, and is specifically related to a kind of flow that is used for used for water injection wells in oil fields and surveys the accent downhole instrument automatically.
Background technology
At present, what each elephant of China adopted when regulating eccentric injection allocation water injection well water injection rate is traditional adjusting technology, the eccentric injection allocation concocting method that uses is now: 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.Throw inspection more again, repeated multiple times, time-consuming, effort is difficult to reach desirable requirement.The water yield of regulating individual layer needs about 6～8 hours (/ hectare sharp), and a bite well is by 4 layers of calculation, and adding the upslide instrument so and dragging for the time that the instrument time regulates a bite well is 5～8 days, and during working expenditure, effort, difficulty and intensity are all bigger.
Cause an important problem of this traditional handicraft to be: also not have a kind of flow to survey the accent downhole instrument automatically at present, present stage, survey the automatic coupling of transferring downhole instrument all can not realize regulating arm and down-hole water nozzle, more do not use to survey and transfer downhole instrument that the injection flow of down-hole water nozzle is regulated and control.
Summary of the invention
The purpose of this utility model is to provide a kind of flow to survey the accent downhole instrument automatically, and it has solved surveys the automatic coupling of transferring downhole instrument can not realize regulating arm and down-hole water nozzle in the background technology, and the technical problem that can't regulate and control of the injection flow of down-hole water nozzle.
Technical solution of the present utility model is:
A kind of flow is surveyed the accent downhole instrument automatically, comprises body 1, and an end of described body 1 is provided with feather key 2, and described body 1 also is provided with flow meter 3, regulating arm 4 successively along an end of feather key 2,
Its special character is:
Regulating arm 4 rear ends of described body 1 also are provided with the power transmission shaft 5 and first motor 6, and an end of described power transmission shaft 5 is connected with regulating arm 4, and the other end is connected with first motor 6.
Also be provided with second motor 7 in the above-mentioned regulating arm 4.
Above-mentioned flow meter 3 is a ultrasonic flowmeter.
The first above-mentioned motor 6 is connected with circuit control device 8.
Here need to prove: the utility model can use a motor, but when being to use a motor, it is complicated that power transmission shaft 5 is just wanted relatively, and at this moment power transmission shaft 5 should satisfy regulating arm 4 and outwards opens along body 1, cooperates with the down-hole water nozzle; After satisfying power transmission shaft 5 again and the down-hole water nozzle cooperating, can realize screwing and unscrewing to the down-hole water nozzle.Certainly, also can use two motors, power transmission shaft 5 is just simple relatively like this, and first motor 6 satisfies regulating arm 4 and outwards opens along body 1 particularly, after second motor 7 satisfies power transmission shaft 5 and the down-hole water nozzle cooperates, can screw and unscrew the realization of down-hole water nozzle.First motor 6 is connected with circuit control device 8 can realize that the ground handling personnel survey the accent downhole instrument automatically to this flow and control.
The utlity model has following advantage:
1, random expansible of the regulating arm of adjuster and withdrawal.Promptly manual intervention can be added at any time, opening and regaining of arm can be controlled to adjust.Instrument the down-hole at any time can more than carry also and can transfer, flexible operation is raised the efficiency.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 shorten 4 to 8 times original duty cycle.
2, two individual motor of design control to adjust the rectilinear motion of axle and rotatablely moving of regulating shaft respectively in the adjuster, make with the electronic water nozzle aperture size of regulating arm coupling 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.

The specific embodiment
Referring to Fig. 1, a kind of flow is surveyed the accent downhole instrument automatically, comprise body 1, an end of body 1 is provided with feather key 2, and body 1 also is provided with flow meter 3, regulating arm 4 successively along an end of feather key 2, regulating arm 4 rear ends of body 1 also are provided with the power transmission shaft 5 and first motor 6, one end of power transmission shaft 5 is connected with regulating arm 4, and the other end is connected with first motor 6, also is provided with second motor 7 in the regulating arm 4, flow meter 3 is a ultrasonic flowmeter, and the first above-mentioned motor 6 is connected with circuit control device 8.
Here need to prove: the utility model can use a motor, but when being to use a motor, it is complicated that power transmission shaft 5 is just wanted relatively, and at this moment power transmission shaft 5 should satisfy regulating arm 4 and outwards opens along body 1, cooperates with the down-hole water nozzle; Satisfy again at power transmission shaft 5 with after the down-hole water nozzle cooperates, can realize screwing and unscrewing the down-hole water nozzle.Certainly, also can use two motors, power transmission shaft 5 is just simple relatively like this, and first motor 6 satisfies regulating arm 4 and outwards opens along body 1 particularly, after second motor 7 satisfies power transmission shaft 5 and the down-hole water nozzle cooperates, can screw and unscrew the realization of down-hole water nozzle.First motor 6 is connected with circuit control device 8 can realize that the ground handling personnel survey the accent downhole instrument automatically to this flow and control.
During work, this flow is surveyed the accent downhole instrument automatically transfer to the aspect that the down-hole needs measurement of discharge, drive first motor 6, outwards open regulating arm 4 by power transmission shaft 5 along body 1, because feather key 2 and regulating arm 4 are along same axial, so regulating arm 4 can be just in time when opening and the electronic water nozzle coupling of down-hole, at this moment can realize flow measurement to this aspect, when needing to change flow, drive second motor 7 that is arranged in the regulating arm 4 again, 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.The utility model has been realized the automatic survey of downhole flow is transferred by the way.
