Zusammenfassung: | The invention discloses an epoxy resin authigenic particle profile adjusting system and application thereof. An oil-in-water emulsion prepared from epoxy resin, a curing agent, an emulsifier, a dispersing agent, water and the like is used for adjusting a liquid production profile to achieve the purposes of stabilizing oil and controlling water. After the oil-in-water emulsion is injected into a stratum, solid particles are generated from liquid phase transformation under the excitation of oil reservoir temperature. The viscosity of the oil-in-water emulsion is slightly higher than that of a water phase, and injection is easy; and solid particles with the controllable size can be produced in pores and throats, the system has the high plugging capacity on the pores and the throats, can be used for adjusting the permeability of reservoirs, limiting the liquid production capacity of the reservoirs with the high water content, starting the low-permeability reservoirs with the relatively low water content and achie |
