| titleOfInvention | A kind of green targeting microcapsule and preparation system, preparation method and application |
| abstract | The invention discloses a green targeting microcapsule and its preparation system, preparation method and application. The oil displacement system includes surfactant and capsule material. The high-efficiency surfactant is encapsulated in micro- and nano-sized microcapsules, which are dispersed in the water phase and dissolved in the oil phase. The size distribution of the microcapsules is controlled according to the formation permeability. The large-sized microcapsules migrate in the large pores in the high-permeability zone and play the role of profile control and plugging. The small-sized microcapsules can enter the reservoir with small pores and migrate to the The low-permeability zone with high residual oil saturation releases surfactant after contact with crude oil, and exerts a targeting effect, which not only solves the challenges of water solubility and temperature and salt resistance of surfactants, but also overcomes the problem of surfactants in storage. The problem of adsorption loss on the surface of the layer medium can improve the recovery of crude oil. |
