Abstract
The utility model provides a flowing well anti-blocking nozzle. The outer side of the inlet end of the nozzle is provided with a threaded button, a through hole is formed in the middle of the nozzle, the outlet end of the through hole is expanded to form a spanner combination hole, the inlet end of the through hole forms a step through twice diameter expanding, a filter net is arranged at the step, and an ejection screwed plug presses and fixes the filter net. When paraffin, salt crystals, formation sands, frac sands and other impurities carried by crude oil at a shaft bottom are exhausted to the through hole, all the impurities are firstly blocked by the filter net and can not block the through hole. In addition, a through hole type or blind hole type spanner anti-sliding groove is formed in the inner wall of the spanner combination hole, when the nozzle is replaced, the spanner anti-sliding groove can be used in cooperation with a spanner with the outer wall being provided with elastic balls, the nozzle can be stably combined with the spanner, and the spanner is prevented from falling down to a pipeline.
Description
Technical field
The utility model relates to the oil nozzle device of using in flowing well petroleum production engineering.
Background technology
Flowing well is to utilize the energy of oil reservoir self that crude oil is lifted to ground, and without other power-equipments, thereby cost for oil production is low.Field production management unit, in order to excavate to greatest extent the productive potentialities of whale, extends its flush stage, all needs to control scientifically and rationally oil well production pressure reduction.
As shown in Figure 1, it is the oil nozzle structure schematic diagram generally adopting at present, described oil nozzle is to utilize raw steel car to become 11/4 " screw buckle 1; process therebetween a through hole 2; be arranged in well head oil muzzle by screw buckle 1; and utilize through hole 2 to make oily passage, the port of export expansion of described through hole 2 is formed with spanner combined hole 3.Because the aperture of through hole 2 is much smaller than resistance oil nozzle sleeve internal diameter, while making liquid through through hole 2, inside and outside generation pressure reduction, utilizes through hole 2 to control oil well production pressure reduction in production.
But, because the crude oil in shaft bottom often carries paraffin, salt crystal, reservoir sand, fracturing sand and other foreign material in self-energy lifting process, when they drain into the import of through hole 2, often stop up oil nozzle, cause oil well to stop production; And in changing the process of oil nozzle, because it is without anti-drop structure, often there is oil nozzle and come off in ducted phenomenon.
Summary of the invention
For the problems referred to above, the purpose of this utility model is, a kind of flowing well anti-blocking oil nozzle is provided, and can prevent that foreign material from stopping up oil nozzle import, guaranteed the unimpeded of gas stream passage.
Another one object of the present utility model, is to provide a kind of flowing well anti-blocking oil nozzle, can prevent that oil nozzle from coming off in pipeline in Renewal process.
For achieving the above object, the technical solution adopted in the utility model is:
A flowing well anti-blocking oil nozzle, is provided with through hole in described oil nozzle, it is characterized in that: the entrance point place of described through hole is provided with filter screen.
In technical scheme preferably:
The entrance point of described through hole is formed with step, and described filter screen is arranged on described step place.
One holds out against plug described filter screen is fixed.
The port of export expansion of described through hole is formed with spanner combined hole.
On the inwall of described spanner combined hole, be formed with spanner on-slip groove.
Described spanner on-slip groove is through hole or blind hole.
Described oil nozzle arrival end outside is processed with screw buckle.
Compared with prior art, adopt the advantage the utlity model has of technique scheme to be:
When paraffin, salt crystal, reservoir sand, fracturing sand and other foreign material that carry when the crude oil in shaft bottom drain into through hole, can first by described filter screen, be blocked, can not stop up through hole; Even if a part of mesh of described filter screen is plugged, the mesh of its other part still can circulate, and can not block completely, has been equivalent to increase the flow channels of crude oil.
In addition, on the inwall of described spanner combined hole, be formed with the spanner on-slip groove of through hole or blind hole form, when changing oil nozzle, described spanner on-slip groove can be used in conjunction with the spanner of outer wall with hoodle, oil nozzle can be stably incorporated on spanner, prevent that spanner from dropping in pipeline.
Accompanying drawing explanation
Fig. 1 be existing flowing well oil nozzle partly cut open structural representation;
Fig. 2 be the flowing well anti-blocking oil nozzle that provides of the utility model partly cut open structural representation.
Description of reference numerals: screw buckle 1; Through hole 2; Spanner combined hole 3; Filter screen 4; Hold out against plug 5; Spanner on-slip groove 6.
The specific embodiment
As shown in Figure 2, be a kind of flowing well anti-blocking oil nozzle that the utility model provides, the arrival end outside of described oil nozzle is processed with screw buckle 1, is processed with through hole 2 in the middle of oil nozzle, and the port of export expansion of described through hole 2 is formed with spanner combined hole 3; Difference from prior art is, the entrance point of described through hole 2 is through twice hole enlargement and be formed with step, 4, one of filter screens is installed at described step place and holds out against plug 5 described filter screen is fixed.
Thus, when paraffin, salt crystal, reservoir sand, fracturing sand and other foreign material that carry when the crude oil in shaft bottom drain into through hole 2, can first by described filter screen 4, be blocked, can not stop up through hole 2; Even if a part of mesh of described filter screen 4 is plugged, the mesh of its other part still can circulate, and can not block completely, has been equivalent to increase the flow channels of crude oil.
In addition, as shown in Figure 2, on the inwall of described spanner combined hole 3, be formed with the spanner on-slip groove 6 of through hole or blind hole form, when changing oil nozzle, can coordinate outer wall to use with the spanner of hoodle, oil nozzle can be stably incorporated on spanner, prevent that spanner from dropping in pipeline.
The utility model has carried out a large amount of long-term experiments in oil field, oil nozzle occlusion event does not together occur so far, has also stopped the phenomenon that oil nozzle comes off in pipeline.
