Reunite.
The technical scheme that the utility model is provided is as follows:
A kind of device for dispersion microsphere transfer drive liquid, including pipe nipple, the pipe nipple be hollow structure, the pipe nipple into
Exporting inside both ends is truncated cone-shaped, which is sequentially reduced along liquid phase flow direction, is uniformly set in the middle part of the pipe nipple
There are multiple liquid channels, the truncated cone-shaped at both ends connects with liquid channel, and the aperture of the liquid channel is 2-5mm.
The truncated cone-shaped bottom diameter and upper bottom diameter ratio are 1:10-1:15.
The truncated cone-shaped height is 5-8cm.
The axial angle of the truncated cone-shaped face and pipe nipple is 30-60 °.
The pipe nipple length is 45-60cm.

The beneficial effects of the utility model are:
This device for dispersion microsphere transfer drive liquid provided by the utility model, first microballoon pass through pipe nipple input end
Enter in pipe nipple after truncated cone-shaped buffering, then the liquid channel passed through, since liquid channel internal diameter is small, microballoon transfer drive liquid is in high pressure water
Flow velocity increases under the jet action of stream, and the microballoon of reunion is broken up and makes it as far as possible uniformly, to improve polymer microballoon
Dispersibility, injection and the mobility of transfer drive liquid make microballoon transfer drive liquid smoothly flow through pit shaft, eventually enter into stratum.
It is described in further details below in conjunction with attached drawing.

Fig. 2 is the cross-sectional view of pipe nipple 4.
In figure: 1, external screw thread；2, liquid channel；3, truncated cone-shaped；4, pipe nipple.
Specific embodiment
Embodiment 1:
In order to enhance dispersibility and uniformity of the polymer microballoon transfer drive liquid in waterflood-transmission line, one is present embodiments provided
Kind is used for the device of dispersion microsphere transfer drive liquid, including pipe nipple 4, and the pipe nipple 4 is hollow structure, the inlet and outlet two of the pipe nipple 4
It is truncated cone-shaped 3 that end is internal, which is sequentially reduced along liquid phase flow direction, is uniformly provided in the middle part of the pipe nipple 4 more
The truncated cone-shaped 3 of a liquid channel 2, both ends connects with liquid channel 2, and the aperture of the liquid channel 2 is 2-5mm.
Truncated cone-shaped 3 primarily serves buffer function, avoids the polymer microballoon reunited blocking liquid channel 2, can not be in high pressure
The interaction jet of water flow disperses.
The device of this dispersion microsphere transfer drive liquid provided in this embodiment increases that is, on waterflood-transmission line in a multistage change
Microballoon transfer drive liquid is carried out spray dispersion using the effect of high pressure water flow, microballoon is avoided to roll into a ball in waterflood-transmission line by the pipe nipple 4 of diameter
It is poly-, enhance the injection and mobility of microspheres solution, makes microballoon full and uniform dispersion before entering stratum, finally promote transfer drive
Workability and implementation result.
Embodiment 2:
On the basis of embodiment 1, a kind of device for dispersion microsphere transfer drive liquid, the rotary table are present embodiments provided
The bottom diameter of shape 3 and upper bottom diameter ratio are 1:10-1:15.
3 height of truncated cone-shaped is 5-8cm.
The axial angle of 3 face of truncated cone-shaped and pipe nipple 4 is 30-60 °.
4 length of pipe nipple is 45-60cm.
The pipe nipple 4 imports and exports both ends and is equipped with external screw thread 1.As shown in Figure 1.
The utility model principle:
Microballoon enters in pipe nipple 4 after being buffered by the truncated cone-shaped 3 of 4 input end of pipe nipple first, then the liquid channel 2 passed through,
Since 2 internal diameter of liquid channel is small, microballoon transfer drive liquid flow velocity under the jet action of high pressure water flow increases, and the microballoon of reunion is broken up
