Description
Technical Field
The utility model belongs to the technical field of oil field production equipment, in particular to sand discharging and oil production jet pump.
Background
In the process of drilling operation and oil field production, due to the reasons of poor well cementation quality, water content increase and the like, a large amount of stratum sand is flushed into a near wellbore zone, enters a well again during production and enters a pump blocking device along with liquid flow, in addition, some old wells with poor well completion quality and lacking of artificial pockets cause the stratum sand to be built at the bottom of an oil well to be accumulated and buried in a production layer, and sand cannot be fished out due to sleeve deformation.
The common sand washing is that a sand washing pipe column is lowered to a sand surface position, high-speed sand washing liquid is input to the bottom of a well by using a ground pump truck, a sand washing pen point and the high-speed liquid flow stir up and wash away settled sand, the mud sand is taken out to the ground by the returned liquid flow, and the normal production cannot be carried out in the sand washing process. In the middle and later stages of oil field development, stratum loss caused by common sand washing is serious, most of well sand washing does not return, sand washing liquid directly enters the stratum and carries settled sand into the stratum, so that the settled sand becomes loose sand which cannot be washed completely, and accidents such as sand burying, sand blocking and the like are caused frequently.
Because the oil well is produced for a long time to cause stratum depletion, the sand washing liquid enters the stratum to cause oil layer pollution during sand washing, simultaneously the discharged liquid is less to seriously influence the sand washing effect, and the sand bailing process has the advantages that the once sand bailing amount in a large amount of sand-accumulating wells is limited, so that the sand bailing efficiency is reduced, the operation period is prolonged, and the labor amount is increased.
SUMMERY OF THE UTILITY MODEL
To the technical problem who exists among the prior art, the utility model provides a sand discharge oil recovery jet pump.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides a sand discharge oil recovery jet pump, includes inner tube, urceolus, sand discharge nozzle, sprays nozzle and diffuser, the cavity has between urceolus and the inner tube, inner tube from the top down is equipped with in proper order diffuser, spray nozzle and sand discharge nozzle, sand discharge nozzle with the injection bore that sprays the nozzle all diminishes along spraying direction gradually, seted up on the lateral wall of the inner tube of sand discharge nozzle top with the inlet of cavity intercommunication, the lower extreme lateral wall of urceolus is equipped with inhales the sand mouth, inhale the sand mouth with the diffuser intercommunication.
Preferably, the sand discharge nozzle and the jet nozzle have a jet caliber which is gradually reduced along the jet direction.
Preferably, an upper end of the injection nozzle extends to an upper end of the sand suction port.
Compared with the prior art, the utility model discloses the beneficial effect who has is: the utility model discloses simple structure inhales the inner tube through the sand setting that forms negative pressure zone around inhaling the sand mouth and will stir to bring ground into, improved oil recovery quality and efficiency.
Drawings
Fig. 1 is a schematic structural view of a sand discharge oil extraction jet pump according to the present invention;
in the figure: 1-an inner cylinder; 2-outer cylinder; 3-a sand discharge nozzle; 4-a spray nozzle; 5-a diffuser; 6-chamber; 7-liquid inlet; 8-a sand sucking port; 9-high pressure chamber.
Detailed Description
So that those skilled in the art can better understand the technical solution of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the embodiment of the utility model discloses a sand discharge and oil production injection pump, including inner tube 1, urceolus 2, sand discharge nozzle 3, injection nozzle 4 and diffuser 5, cavity 6 has between urceolus 2 and the inner tube 1, and inner tube 1 from the top down is equipped with diffuser 5, injection nozzle 4 and sand discharge nozzle 3 in proper order, offers on the lateral wall of the inner tube 1 of sand discharge nozzle 3 top with the inlet 7 of cavity 6 intercommunication, and the lower extreme lateral wall of urceolus 2 is equipped with inhales sand mouth 8, inhales sand mouth 8 and diffuser 5 intercommunication.
In this embodiment, the injection apertures of the sand discharge nozzle 3 and the injection nozzle 4 are gradually reduced along the injection direction, so as to respectively facilitate the formation of high pressure and negative pressure, and further facilitate the respective stirring and suction of sand.
In this embodiment, the upper end of the injection nozzle 4 extends to the upper end of the sand suction port 8, which is more favorable for forming a negative pressure region around the outer sand suction port.
The utility model provides a sand discharge oil recovery jet pump's theory of operation is, and the high pressure sand washing liquid that comes from ground power pump gets into cavity 6 by power liquid pipe, then gets into the high-pressure chamber 9 between sand discharge nozzle 3 and the injection nozzle 4 through inlet 7, then, and high pressure sand washing liquid divide into two directions in the high-pressure chamber. Wherein, 40% of high-pressure sand washing liquid is sprayed out from the sand discharge nozzle 3 to impact the bottom of the well, and after sand setting is stirred, the sand setting returns to the sand suction port 8; 60% of high-pressure sand washing liquid is sprayed out from the spray nozzle 4 at a high speed, and the liquid flow speed is high, so that the pressure around the liquid column is reduced, and a negative pressure area is formed. Under the action of the pressure difference between the bottom pressure and the negative pressure area, the sand suction port 8 sucks the settled sand stirred up by the sand discharge nozzle 3 and the waste power liquid which works into the diffuser 5 together, the settled sand enters the diffuser 5 under the carrying of high-speed jet flow, the speed is reduced, and the pressure is increased to the proper discharge pressure of the jet pump. The mixed sand carrying liquid returns to the ground along the inner cylinder 1 and is gradually lowered along with the sand washer to complete the whole sand washing work.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
