The specific embodiment of the fluid level depth of oil well measuring device of the utility model, fluid level depth of oil well measuring device
Including sound source occur module, signal receiving module and signal processing module, signal receiving module and signal processing module with it is existing
Technology is identical, is not described in detail.As shown in Figure 1, sound source occur module include cylinder 1, piston 3, piston rod 2, valve seat 6,
Taper valve 7, position-limiting cover 8, branch pipe 10, jointing 21, link assembly 22 and actuating spanner 23 etc..Cylinder 1 it is open at one end
The other end blocks, that is, has and block end 12 and open end 11, blocks and is coated with piston rod 2,2 inner end of piston rod on the sealing plate at end 12
It is connect with piston 3.2 outer end of piston rod connects driving mechanism or connection manual actuation structure, uses link assembly in the present embodiment
22 and actuating spanner 23 form manual actuation structure, can be with the free skating in cylinder 1 of piston 3 by pulling actuating spanner 23
It is dynamic.Piston 3 be moved to be adjacent to block end 12 when for 3 movement travel of piston the first limit position.On side wall at open end 11
Equipped with side opening 5, the side of the separate microphone 20 of side opening 5 is disposed with position-limiting cover 8 and valve seat 6, and position-limiting cover 8 with it is all
It is provided with taper valve 7 between your seat 6, is closed when taper valve 7 and valve seat 6 are formed in piston 3 far from valve seat 6, in work
The check valve opened when plug 3 is close to valve seat 6, taper valve 7 and valve seat 6 carry out one-way sealing by the conical surface, and position-limiting cover 8 is used
It is limited in taper valve 7, prevents taper valve 7 from opening excessive and falling.Air-flow through-hole 9 is provided on position-limiting cover 8, with
Gas supply stream passes through.
Open end 11 is equipped with jointing 21 and makes the open end 11 of cylinder 1 after connection for the casing connection with oil well
The casing of face oil well and the annular space of oil pipe, the sound wave of generation are propagated in the annular space i.e. between casing and oil pipe.
The side opening 5 is located between the open end 11 and position-limiting cover 8 of cylinder 1.20 company of being mounted on of microphone as signal receiving module
At connector 21, for received voice signal to be converted to electric signal.It is work that piston 3, which moves to and is adjacent to the position of valve seat 6,
Fill in the second limit position of 3 movement travels.Negative pressure sound wave occurs hole 4 and side opening 5 and is interconnected by branch pipe 10, and branch pipe 10 is in cylinder
1 outside is connect with cylinder 1.
At work, piston rod 2 is driven to move and pulling actuating spanner 23, piston rod 2 is with piston 3 in cylinder 1
Back and forth movement is carried out between interior the first limit position and the second limit position.("upper" as described below refers to the side in figure to 3 uplink of piston
To referring to direction of the piston 3 far from valve seat 6；"lower" as described below refers to piston 3 close to the direction of valve seat 6) process:
As shown in Fig. 2, piston 3 is from the second limit position close to valve seat 6, gradually uplink, taper valve 7 are sealed against each other with valve seat 6,
So that the space between valve seat 6 and piston 3 forms confined space, gradually the space is aspirated during 3 uplink of piston
And the negative pressure cavity of a subnormal ambient is formed, vacuum degree of the suction strength in negative pressure cavity in other words in negative pressure cavity is gradually increased,
As shown in figure 3, until when piston 3 goes upward at negative pressure sound wave generation hole 4 and gradually merges out negative pressure sound wave generation hole 4, branch pipe
10 occur hole 4 by negative pressure sound wave is connected to negative pressure cavity, under the powerful suction function accumulated in negative pressure cavity, the sky of open end 11
Gas occurs hole 4 from negative pressure sound wave along 10 moment of branch pipe and pours negative pressure cavity, causes infrasound；During 3 downlink of piston: such as Fig. 4
Shown, piston 3 is crossed after hole 4 occurs for negative pressure sound wave from the first limit position and is continued traveling downwardly, and the air that gradually reduces, so that piston 3
Positive pressure chamber is formed between valve seat 6, the intracavitary air of positive pressure is in barotropic state, with piston 3 downlink to positive pressure chamber into one
Step compression forces taper valve 7 and valve after the intracavitary pressure of positive pressure reaches more than the setting pressure of the unlatching of taper valve 7
Seat 6 separates, so that check valve is opened；In the movement between the first limit position and the second limit position repeatedly of piston 3, make it possible to
Constantly generate negative pressure sound wave, and due to negative pressure sound wave be by being compressed to the infrasound that abrupt release generates after certain negative pressure,
Quality is relatively high, and the attenuation rate of sound wave is lower, interference free performance is more superior, so that subsequent measurement is more accurate.
Needs are produced according to oil wells in field work circumstances safe, change and former additional sound source medium is replaced to select devoid of risk
Well head connects sounding gun apparatus, the sound source generated when not influencing source quality by the movement of device own institutions.Scene
Connect the pressure-exchange sound wave medium that simultaneously moment conversion generates after well head test negative pressure sound wave rifle operating device negative pressure stroke, signal
Liquid level back reflection is moved to along the oil casing annular space direction of propagation and returns well head, and microphone will be converted after the acoustic pressure of impression on device
It at voltage signal, transmits and records reflected sonic signals to echometer, to obtain record dynamic oil level data.
Oil well surveys hydrodynamic face negative pressure sound wave rifle in more than the 10 mouth well application such as H7-118, J7-908 well, and gun body is not connected to and pacifies
Fill any pressure vessel and sound bearing medium.It is operated by own institutions and generates negative pressure sound wave (infrasound), by micro- in gun body
Acoustic signals are become voltage signal by sound device.
Examples comparative effect: H7-118 casing pressure 0.8MPa, pressure test original well head sounding device and 12MPa pressure
Test operation after nitrogen gas tank installation connection, liquid level Curves Recognition pit shaft inner sleeve box cupling 43 and 1870 meters of dynamic oil level.And
Using well head test negative pressure sound wave sling pressure test curve identification pit shaft inner sleeve box cupling 75 and 1870 meters of dynamic oil level,
J7-908 does not cover operating curve under pressure environment and is more clear.
Oil well will change after surveying the application of hydrodynamic face negative pressure sound wave gun apparatus and replace former additional sound source meson mode of operation, no
Use different types of vessel medias such as the additional sound bullet of former wellhead connection device, electronic sound or high-pressure nitrogen bottle oily as surveying
Well hydrodynamic area source of sound.It realizes operation consumptive material zero cost, has prevented security risk.It is expected that the annual every 100 mouthfuls of wells in oil field save nitrogen
Or sound bullet medium puts into 6 Wan Yuyuan.
The embodiment of the sound wave rifle of the utility model is identical as sound source generation each embodiment of module in above-described embodiment,
It repeats no more.
