Background

At present, the polymer microsphere profile control and flooding technology is widely applied as a technical means for improving water flooding, controlling water and stabilizing oil in an oil field. The polymer microsphere is a microemulsion, the viscosity of base fluid is low, the polymer microsphere can be injected into a stratum along with a water injection pipeline on line, the particle size of the microsphere is generally between nano-scale and micron-scale, and the polymer microsphere is dispersed into a pore space by a plurality of microsphere individuals to play a role in profile control and flooding; however, due to the chemical synthesis process, the small particle size of the microspheres, the product performance and other reasons, in the process of injecting the microspheres on line, the microsphere solution with the micro-nano particle size is easy to agglomerate, i.e. agglomerate, so that the viscosity of the microsphere base solution is increased and thickened, the fluidity is deteriorated, and the blockage in a water injection pipeline can be caused seriously.

The prior art patent publication No. CN209195384U provides a device for dispersing microspheres to adjust and drive liquid; the device firstly buffers the microspheres through the circular truncated cone at the inlet end of the short section and then enters the short section, and then the microspheres pass through the liquid phase channel, so that the inner diameter of the liquid phase channel is small, the flow velocity of the microsphere profile control and flooding liquid is increased under the jet flow effect of high-pressure water flow, the agglomerated microspheres are dispersed and are as uniform as possible, the dispersity, the injectivity and the flowability of the polymer microsphere profile control and flooding liquid are improved, and the microsphere profile control and flooding liquid smoothly flows through a shaft and finally enters a stratum.

Although the device has more beneficial effects, the following problems still exist: the device only disperses the microspheres through the mode of liquid phase channel cooperation rivers impact, but, when the microspheres were comparable to the liquid phase channel pore size, the microspheres would cause the jam to the liquid phase channel, and the rivers of impact are difficult to wash it through the liquid phase channel, and if the rivers of impact wash it through the liquid phase channel, then lead to liquid phase channel pore size grow for this liquid phase channel loses the dispersion effect. In view of this, we propose a device for dispersing microsphere flooding fluid.
