Abstract

The utility model discloses a sound wave self vibration oil increasing device which relates an accessory used for mechanical oil production in an oil field. The utility model is characterized in that a sieve tube is sheathed with a positioning device and a rubber plug, wherein the lower end of the sieve tube is connected with a vibrator via threads and the outer surface of the vibrator is provided with a vibrating sheet. The inner end of the vibrator is provided with a valve seat and a valve ball, the lower end of the vibrator is provided with a butterfly valve and the butterfly valve has an open angle between 35 DEG and 40 DEG. The vibrator can send out sound waves during the process of pumping oil via an oil pump, an oil layer is energized to vibrate, the seepage situation of the oil layer is improved and the clogging of the oil layer is gradually eliminated. The open angle of the butterfly valve is between 35 DEG and 40 DEG is favorable for closing the butterfly valve in time, the vibrator can generate strong shock and the clogging of the oil layer is easy to eliminate. The utility model is used in an oil well for mechanical oil production.

Description

Sound wave self-vibration oil increasing device

Technical field

The utility model relates to a kind of accessory in the oil field machinery oil.

Background technology

In oilfield development process, owing to reasons such as drilling well, completion, pressure break can cause the pollution of mechanical admixture to the oil reservoir near wellbore zone, perhaps make the bacteria breed in the formation fluid, perhaps fouling and wax deposition take place in stratum itself, often with oil layer blocking, reduced reservoir permeability, oil well output is descended.Be necessary near wellbore formation is handled for this reason.Pressure break, acidifying are conventional de-plugging measures, adopt pressure break or acidization tool to carry out the de-plugging work of oil reservoir, not only to consume wide variety of materials, also need to drop into many manpowers, vehicle carries out operation, consume lot of manpower and material resources, oil well also will stop to produce, and these de-plugging measure meetings simultaneously bring secondary pollution to oil reservoir.

The utility model content

The purpose of this utility model provides a kind of simple in structure, easily manufactured sound wave self-vibration oil increasing device, uses it when utilizing oil well pump to recover the oil, and can automatically terminate formation blockage.

Technical solution of the present utility model is to realize like this, a kind of sound wave self-vibration oil increasing device, it is characterized in that, (1) connects mutually with box cupling by screw thread by screen casing, on screen casing, be set with locator and plug, connect mutually with vibrator by screw thread in the screen casing lower end, have vibrating reed on the external surface of vibrator.(2) top in vibrator has valve seat, and valve ball is housed on valve seat.(3) in the vibrator lower end dish valve is housed, the opening angle of dish valve is 35 °-40 °.

Usefulness of the present utility model is, (1) this utility model is installed in the below of oil well pump, makes vibrator over against the oil reservoir place, during oil well pump is pumped, valve ball in vibrator can ceaselessly rise or fall, when it falls, can make vibrator produce vibration, send sound wave, acoustic wave action is on the stratum, the excitation oil reservoir shakes, thereby improves the seepage flow situation of oil reservoir, removes oil layer blocking gradually.(2) opening angle of dish valve adopts 35 °-40 °, and this angle helps the dish valve in time closes, and makes vibrator produce stronger vibrations, removes oil layer blocking easily.

Description of drawings

Fig. 1 is that the utility model is installed in the schematic diagram in the oil well.

Fig. 2 is the dish valve arrangement schematic diagram in the utility model.

The specific embodiment

Locator 4 and plug 7 are sleeved on the screen casing 5, valve ball is placed on the valve opening in the vibrator 8, on the external surface of vibrator 8, be fixed with 10-30 sheet vibrating reed 9, screen casing 5 upper ends are connect with box cupling 3, oil pipe 2, oil well pump 1 successively mutually by screw thread, vibrator 8 lower ends connect with dish valve 10, floral tube 11 mutually by screw thread, and they are installed in the sleeve pipe 6 in the pit shaft.Valve seat in vibrator 8 is to fall 45 in the upper end of endoporus.Dish valve body 12 is tubular articles, and there is internal thread its upper end, and external screw thread is arranged at the bottom, and bearing 14 is installed in the lower end of dish valve body 12 by screw, and dish plate 13 and bearing 14 are bound up by pin 15.Chamfering size on control dish plate 13 left ends can be controlled dish plate 13 open angles, makes its opening angle between 35 °-40 °.

Claims

A kind of sound wave self-vibration oil increasing device is characterized in that,

1. connect mutually with box cupling (3) by screw thread by screen casing (5), on screen casing (5), be set with locator (4) and plug (7), connect mutually with vibrator (8) by screw thread, have vibrating reed (9) on the external surface of vibrator (8) in screen casing (5) lower end;

2. the top in vibrator (8) has valve seat, and valve ball is housed on valve seat;
