Abstract:

During the long-term water flooding phase, the oil recovery operation becomes more difficult due to the reservoirs’ permeability, which increases considerably during the oil field development process. In general, to ameliorate the conditions for good enhanced oil recovery, it necessary to improve the displacement efficiency of displacement agents and improve sweep efficiency. Therefore, the alkali/surfactant/polymer combination flooding system techniques have been the required solution for enhanced oil recovery. However, in porous media, the reservoir temperature and salinity, the sheer deterioration, and the dilution effect affected the viscosity and viscoelasticity of the alkaline-surfactant-polymer combination’s flooding systems. In addition, on the polymer molecular, the negative alkali ion neutralizes and forming a band molecule structure. The polymer’s molecular structure is transformed and changed. Consequently, the polymer solution’s viscosity and viscoelasticity are decreased. Our group’s previous studies reported that the dispersed particle gel prepared by shearing bulk gel has excellent characteristics, such as softness, viscoelasticity, high-temperature tolerance, thermal stability, and high expansion. The dispersed particle gel can plug the high permeability zones through aggregation in pores and throats and can also effectively improve the profile control through direct plugging or bridging across pore throats in the formation. These characteristics demonstrate great potential for the strengthened dispersed particle gel/alkali/surfactant/polymer combination flooding system. The addition of dispersed particle gel to strengthened the alkali/surfactant/polymer combination flooding system interleaves in the three-dimensional network structure and has a synergistic viscosity increase effect by increasing the combination flooding system’s stability in the solution.
