Description
Technical field
The invention belongs to oil gas field well testing device technique field, relate to the well head sounding dress of oil and gas well testing level
Put, particularly relate to a kind of well head vocal technique without gas circulation and device thereof.
Background technology
Oil gas field needs to test annulus liquid level to well head distance (hereinafter referred to as level) this ginseng aborning at present
Number.Test level uses inflation percussion or venting percussion, is exactly i.e.: on oil well and non-corrosiveness gas well, tester
Device connects with sleeve pipe, by inflating or will put outside casing gas the required sound wave of generation test in sleeve pipe；Carry out at high sour gas well
During venting test, need to be reclaimed or enter vent gas treatment pond by outer venting body gas cylinder to carry out harmless treatment.In existing survey
In method for testing, Oil/gas Well sleeve pipe and the external world have gas to circulate all the time, there is gas leakage hidden danger.
Summary of the invention
It is an object of the invention to provide a kind of well head vocal technique without gas circulation and device thereof, to solve existing well
Mouth device sounding needs the problem that gas circulates.
The present invention is achieved in that
A kind of well head vocal technique without gas circulation, it is by micro-to a magnetostriction ultrasonic transducer and a high frequency
Sound device one device of composition；Ultrasonic magnetostrictive transducer is driven by the alternating current of 20K～25K and sends ultrasound wave, sends
A ultrasound wave part can by receive high frequency mike receive, another part after shaft bottom liquid level reflects by high frequency microphony
Device receives, and it is exactly the well head time t to liquid level divided by 2 that high frequency mike receives the time difference of signal for twice；By joint hoop
Between the joint hoop ripple that obtains of reflection combine tubing length and just can calculate the speed v of ultrasonic propagation, be multiplied by time t by speed v
Can be obtained by level position.
Present invention employs such a kind of well head sound-producing device without gas circulation, this device includes at least one mangneto
Flexible ultrasonic transducer and at least one high frequency mike, high frequency mike connects a power supply signal line combination.The present invention's
There is gas exchange due to the discord external world between each parts of device, can accomplish to fully seal.
The present invention solves the problem that wellhead assembly sounding needs gas to circulate in the market, has simple in construction, peace
The advantage such as the most reliable.And this device uses electricity sounding, Oil/gas Well and the external world without gas exchange, stops gas circulation hidden danger；Right
Electromagnetic valve can also be overcome to draw motionless in the well that air pressure is high and test unsuccessful deficiency.
Accompanying drawing explanation
Fig. 1 is assembly of the invention structure diagram.
Being respectively labeled as in figure: 1-high frequency mike, 2-magnetostriction ultrasonic transducer, 3-power supply signal line combines.
Detailed description of the invention
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, this well head sound-producing device without gas circulation of the present invention, it is by high frequency mike 1 and mangneto
Flexible ultrasonic transducer 2 combines in a housing, and ultrasonic magnetostrictive transducer 2 is driven by the alternating current of 20K～25K and sends out
Going out ultrasound wave, high frequency mike 1 connects power supply signal line combination 3, and power supply signal line combination 3 is by supply line and signal line
Combine.
The present invention is implemented:
As it is shown in figure 1, first, ultrasonic magnetostrictive transducer 2 is driven by the alternating current of 20K～25K and sends ultrasound wave,
The ultrasound wave sent is divided into two parts, and a portion can be received high frequency mike 1 and receive, and another part is through shaft bottom liquid level
Received by high frequency mike 1 after reflecting；
It is exactly the well head time t to liquid level divided by 2 that high frequency mike 1 receives the time difference of signal for twice；
The joint hoop ripple that reflection between being bound round by joint is obtained combines tubing length and just can calculate the speed of ultrasonic propagation
V, is multiplied by time t by speed v and can be obtained by level position.
There is gas exchange due to the discord external world between each parts, can accomplish to fully seal.
Certainly, being more than the concrete exemplary applications of the present invention, the present invention also has other embodiment, and all employings are equal to
Replace or the technical scheme of equivalent transformation formation, within all falling within protection domain of the presently claimed invention.
