The present invention relates to oil recovery technique field, particularly relate to a kind of ultrasonic transmitter increasing oil for de-plugging of well.
Background technology
In oil mining process, usually can form some obstructions because of a variety of causes in oil well, hinder crude oil to flow in pit shaft, reduce the permeability on stratum.Ultrasonic oil production technology is then the nearly well oil reservoir by sonicated production well, water injection well, and the physical property of fluid in oil reservoir and fluidised form are changed, and improves circulation condition and the permeability of near wellbore zone, shaft bottom, removes the blocking of producing well, water injection well.The ultrasonic wave of system composition increases oily equipment primarily of part compositions such as magnetic orientation system, special transmission cable, high-power ultrasonics signal of telecommunication emitter and ultrasonic wave electroacoustic transducers.The highpowerpulse electric oscillation signal that it utilizes ground on-vehicle large power supersonic wave transmitter to produce, pass through special transmission cable, Pulse Electric oscillator signal is transferred on the piezoelectric ceramic electro-acoustic conversion of oil reservoir, ultrasonic wave is converted to through electroacoustic transducer, inject in oil bearing bed, realize effect of Ultrasonic oil production de-plugging.
At present, in oil mining process, generally adopt traditional totally enclosed transducer of single drum type brake to produce ultrasonic wave, but this kind of transducer can only rely on outer tube wall to dispel the heat, because its outer wall area of dissipation is limited, thus cause its internal temperature in the course of work too high, now, the heat that piezoelectric ceramics is assembled can not effectively distribute, and causes silicone oil to heat up and expands, and the impedance of transducer is risen; Because resistance increases, and then also just reduce the ultrasonic wave emission effciency of transducer.
Summary of the invention
The object of the invention is to, for solving the closed transducer of existing single drum type brake in the course of the work, the problem that the ultrasonic wave emission effciency of transducer caused due to radiating effect difference is low, the invention provides a kind of ultrasonic transmitter increasing oil for de-plugging of well, this ultrasonic transmitter is by arranging inner and outer tubes, the profit in external environment is made to be full of interior pipe, and then make two sidewalls being placed in the piezoelectric ceramic tube between this interior pipe and outer tube be subject to the cooling effect of profit simultaneously, improve the radiating effect of transducer, reduce impedance.
For achieving the above object, the invention provides a kind of ultrasonic transmitter increasing oil for de-plugging of well, comprise: outer tube, piezoelectric ceramics electric wire, cable interface and cable, described cable interface is used for the piezoelectric ceramics electric wire of drawing in outer tube to transfer into cable, and described cable is for connecting high-frequency pulse signal emitter; It is characterized in that, described ultrasonic transmitter also comprises: the piezoelectric ceramic tube of interior pipe, several hollows and support; Coaxially fixed by support between described inner and outer tubes, two mouth of pipe and external environment connect; Be arranged with several piezoelectric ceramic tubes vertically between this outer tube and interior pipe, described piezoelectric ceramic tube is connected with the piezoelectric ceramics electric wire in outer tube.
As the further improvement of technique scheme, described support is annular pallet, and the center of described annular pallet wears interior pipe, and this annular pallet also offers cannelure, for wearing outer tube.
As the further improvement of technique scheme, outside described annular pallet, sealing mat, on the outer wall of interior pipe, and to be squeezed between annular pallet and sealing gland by gland by nested sealing mat and the gland of being provided with successively.
As the further improvement of technique scheme, the outer wall of described interior pipe one end is arranged with lower pressing cap, and this lower pressing cap is tapered tubular structure, for the fastening gland with contacting at the bottom of its cone; The other end of this interior pipe is provided with piezoelectric ceramics wire seal box, and described piezoelectric ceramics wire seal box is fixed on the external surface of gland, and this piezoelectric ceramics wire seal box is used for the piezoelectric ceramics wire seal of will draw in outer tube.
As the further improvement of technique scheme, the outside of described piezoelectric ceramics wire seal box is provided with several pull bar posts, and one end of this pull bar post is fixed on gland, and its other end is fixed on wire seal device; This wire seal device is used for hermetically-sealed cable interface.
A kind of advantage increasing the ultrasonic transmitter of oil for de-plugging of well of the present invention is:
Because in ultrasonic transmitter of the present invention, pipe is filled with the profit of flowing, and the outer wall of outer tube is also immersed in same profit, and the heat in ultrasonic transmitter can not be heated up and cause resistance to increase by Quick diffusing in a liquid.In ASP flooding test, the impedance value that active well section records before operation is entered under ultrasonic transmitter of the present invention, still constant after the operation of several hours, compare traditional transducer work same amount of time to decline tens megaohms, this ultrasonic transmitter can keep equalized temperature, effectively raise hyperacoustic emission effciency, reduce the consumption of the energy.

Detailed description of the invention
Below in conjunction with drawings and Examples, a kind of ultrasonic transmitter for de-plugging of well increasing oil of the present invention is described in detail.
As shown in Figure 1, a kind of ultrasonic transmitter increasing oil for de-plugging of well of the present invention, so-called ultrasonic transmitter is the ultrasonic transmitter that the physics de-plugging be applied in oil-water well increases oily augmented injection, and it comprises: the piezoelectric ceramic tube 10 of interior pipe 8, outer tube 9, piezoelectric ceramics electric wire 12, cable interface 1, cable 13, several hollows and support; Described cable interface 1 is for transferring into cable 13 by the piezoelectric ceramics electric wire 12 of drawing in outer tube 9, and described cable 13 is for connecting high-frequency pulse signal emitter; Described outer tube 9 is nested on interior pipe 8, is coaxially fixed, two mouths of pipe of this interior pipe 8 and external environment connect between this interior pipe 8 and outer tube 9 by support; Be arranged with several piezoelectric ceramic tubes 10 between this outer tube 9 and interior pipe 8 vertically, described piezoelectric ceramic tube 10 can be fixed on the outer wall of interior pipe 8, and described piezoelectric ceramic tube 10 is connected with the piezoelectric ceramics electric wire 12 in outer tube 9.
Based on the structure of the ultrasonic transmitter in above-described embodiment, as shown in Figure 1, described support is annular pallet 7, in the present embodiment, the two ends of described interior pipe 8 all can be provided with an annular pallet 7, and the two ends of described interior pipe 8 are equipped with an annular pallet 7, and the center of described annular pallet 7 wears interior pipe 8, this annular pallet 7 also offers cannelure, for wearing outer tube 9; Pipe 8 and outer tube 9 in fixing by two annular pallets 7.Outside described annular pallet 7 successively nested sealing mat 6 and the gland 5 of being provided with on the outer wall of interior pipe 8, described gland 5 and sealing mat 6 are all nested on the outer wall of interior pipe 8, and are pressed between annular pallet 7 and sealing gland 5 by sealing mat 6 by gland 5.
