Abstract

Abstract:

For reservoirs with high heterogeneity, low permeability and complex pore structure, the water cut sharply increases in the late-stage development by water injection, and ordinary water flooding and polymer flooding methods are difficult to obtain oil. In contrast, the composite ionic polymer gel has good reservoir adaptability, good compatibility with injected sewage, controllable gelation time, strong adsorption and retention capacity, and good resistance to erosion. Its strong injection ability and wide spread range can not only seal the large pores of the reservoir （namely "profile-controlling"）, but also can drive the remaining oil in the reservoir （namely "flooding"）, and thus can meet the requirements of large-dose injection of the profile-controlling and flooding system. In this paper, formula optimization and performance evaluation were both carried out for the profile-controlling and flooding system based on composite ionic gel. The experimental results show that the system has good salt resistance, shear resistance, thermal stability and viscoelasticity.

Key words: zwitterionic polymer, profile-controlling and flooding system, salt resistance, shear resistance, thermal stability, viscoelasticity
