Description

A kind of device for dispersion microsphere transfer drive liquid
Technical field
The utility model belongs to the transfer drive technical field in DP technology, and in particular to one kind is used for dispersion microsphere transfer drive liquid Device.
Background technique
Currently, polymer microballoon transfer drive technology is answered extensively as the technological means of oil field improving ecology, water and oil control With.Polymer microballoon is a kind of microemulsion, and base fluid viscosity is low, can be with waterflood-transmission line online injection to stratum, microspherulite diameter one As in nanoscale between micron order, be dispersed in interstitial space by large number of microballoon individual and play transfer drive effect.
It is micro- during microballoon online injection but due to chemical synthesis process, the small, properties of product of microspherulite diameter etc. Receive grade partial size microspheres solution be easy aggregation it is agglomerating, that is, reunite so that microballoon base fluid viscosity increase, retrogradation, cause to flow Property be deteriorated, it is serious to be blocked in waterflood-transmission line.
Utility model content
The purpose of the utility model is to overcome the above-mentioned technical problems in the prior art, provide one for dispersion microsphere Microballoon transfer drive liquid is carried out spray dispersion using the effect of high pressure water flow, avoids microballoon in waterflood-transmission line by the device of transfer drive liquid 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.
Pipe nipple inlet and outlet both ends are equipped with external screw thread.
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.
Detailed description of the invention
Fig. 1 is a kind of embodiment schematic diagram of the utility model;
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 And it is made uniformly to improve the dispersibility of polymer microballoon transfer drive liquid, injection and mobility, to make microballoon transfer drive as far as possible Liquid smoothly flows through pit shaft, eventually enters into stratum.
The dispersion microsphere transfer drive liquid device is connected to the medium position of distributing room for water injection Yu the direct waterflood-transmission line of wellhead of water injection well, short It is identical as waterflood-transmission line outer diameter to save 4 outer diameters, 4 external screw thread 1(pin thread of pipe nipple) it is connect by female thread with waterflood-transmission line.
The apparatus structure is simple, easy to use, by 2 variable diameter of liquid channel, is dispersed by high-pressure jet, can avoid polymerization Object microballoon transfer drive liquid is reunited in waterflood-transmission line, to promote the dispersibility of polymer microballoon transfer drive liquid, injection and mobility.
Embodiment 3:
On the basis of embodiment 2, a kind of device for dispersion microsphere transfer drive liquid is present embodiments provided, pipe nipple 4 is long 50cm, 4 both ends of pipe nipple are external screw thread 1, and 4 middle part of pipe nipple forms (as shown in Figure 2), liquid channel by 10-12 liquid channel 2 2 arrival end and outlet end are the design of truncated cone-shaped 3, and the axial angle with 3 face of truncated cone-shaped in channel is 45 °.In pipe nipple 4 in addition to channel It is solid.
In application, the medium position of selection distributing room for water injection and wellhead of water injection well waterflood-transmission line accesses pipe nipple 4.4 input end of pipe nipple Pin thread is connect with the waterflood-transmission line in distributing room for water injection direction using female thread, the waterflood-transmission line of pipe nipple 4 outlet end pin thread and water injection well direction It is connected using female thread.
In polymer microballoon transfer drive liquid injection process, when transfer drive liquid stream is through this pipe nipple 4, since channel becomes smaller, microballoon tune It drives liquid flow velocity under the jet action of high pressure water flow to increase, the microballoon of reunion is broken up and makes it as far as possible uniformly, to be promoted Dispersibility, injection and the mobility of polymer microballoon transfer drive liquid, makes microballoon transfer drive liquid smoothly flow through pit shaft, eventually enter into ground Layer.
