Abstract
A kind of chemical flooding injects flow plug with layering, formed by top connection (1) and choked flow core (2), after described top connection (1) is threaded with choked flow core (2), be contained in the inclined to one side hole of chemical flooding layering injection device, it is characterized in that, described choked flow core (2) coordinates with the smooth interior surfaces in inclined to one side hole, forms labyrinth type flow channels (26).While adopting this device, due to the effect of labyrinth type flow channels, the flow field of liquid stream is repeatedly redistributed and consumed energy, form resistance and control the flow of chemical liquids, so both can control flow, can make again the viscosity loss of the chemical liquids by flow control device minimum, keep the stability of chemical liquids, this is important measures that improve chemical flooding effect.
Description
Technical field
The utility model relates to a kind of oil extraction in oil field process unit, and specifically a kind of chemical flooding injects flow plug with layering.
Background technology
The application of chemical flooding dispensing technology in oil field is at present more and more general, applied hole condition becomes increasingly complex, the complex structure of flow plug for traditional chemical flooding, in controlling flow, viscosity loss to the chemical liquids by flow control device is larger, can not keep the stability of chemical liquids, chemical flooding effect cannot meet the needs of all situations.
Summary of the invention
The purpose of this utility model is to provide the layering of a kind of chemical flooding and injects flow plug, the complex structure existing to solve prior art, in controlling flow, viscosity loss to the chemical liquids by flow control device is larger, can not keep the stability of chemical liquids, chemical flooding effect cannot meet the problem of all situations needs.
The technical solution of the utility model is achieved in the following ways: a kind of chemical flooding injects flow plug with layering, formed by top connection and choked flow core, after described top connection is threaded with choked flow core, be contained in the inclined to one side hole of chemical flooding layering injection device, it is characterized in that, described choked flow core coordinates with the smooth interior surfaces in inclined to one side hole, forms labyrinth type flow channels.
Arrival end, central post, left block, right block and the port of export that described choked flow core is arranged by identical axle center form, top at central post is connected respectively with bottom the port of export and the arrival end that shape of cross section is kidney-shaped, is connected on the central post between arrival end and the port of export to multiple left blocks and right block interleaved; Left block and right block be shaped as the plectane that cuts vertically smaller part portion, left block is identical with right block shape, is symmetrical set; The diameter of the outer peripheral face of described arrival end, left block and right block is identical, and matches with the inner surface in described inclined to one side hole; The radius of this central post is less than the least radius of arrival end, left block, right block and the port of export, formation labyrinth type flow channels around the part lacking of this arrival end, left block, right block, the port of export and central post.
While adopting this device, due to the effect of labyrinth type flow channels, the flow field of liquid stream is repeatedly redistributed and consumed energy, form resistance and control the flow of chemical liquids, so both can control flow, can make again the viscosity loss of the chemical liquids by flow control device minimum, keep the stability of chemical liquids, this is important measures that improve chemical flooding effect.

Detailed description of the invention
Referring to Fig. 1-7, the utility model is that flow plug is injected in the layering of a kind of chemical flooding, formed by top connection 1, choked flow core 2, after wherein top connection 1 is threaded with choked flow core 2, be contained in the inclined to one side hole 3 of chemical flooding dispenser (prior art), coordinate with the smooth interior surfaces in inclined to one side hole 3, form labyrinth type flow channels 26.
Arrival end 25, central post 22, left block 23, right block 24 and the port of export 21 that described choked flow core 2 is arranged by identical axle center form, and are connected respectively the port of export 21 and the arrival end 25 that shape of cross section is kidney-shaped in top and the bottom of central post 22.Multiple left blocks 23 and right block 24 are equidistantly connected on the central post 22 between arrival end 25 and the port of export 21 alternately.Left block 23 and right block 24 be shaped as the plectane that cuts vertically smaller part portion, left block 23 is identical with right block 24 shapes, is symmetrical set.Described arrival end 25, left block 23 are identical with the diameter of the outer peripheral face of right block 24, and match with the inner surface in described inclined to one side hole.The radius of this central post 22 is less than the least radius of arrival end 25, left block 23, right block 24 and the port of export 21, formation labyrinth type flow channels 26 around the part lacking of this arrival end 25, left block 23, right block 24, the port of export 21 and central post 22.When choked flow liquid enters behind the lower end in inclined to one side hole 3, first enter the entrance of labyrinth type flow channels 26 by arrival end 25, along the path of the arrow indication shown in Fig. 3, finally flowed out by the port of export 21 of upper end.
