摘要

In this study, a kind of novel profile control agent, polymer/montmorillonite composite particle (PMCP), which was prepared by an in situ intercalative polymerization method involving rubbers and a hydrophobic monomer (HM), was provided with the aim to modify the injection profile for enhancing oil recovery. The chemical structure of the PMCP was characterized by Fourier transform infrared spectroscopy and X-ray diffraction, respectively. The results prove that the intercalation effect occurred between the polymer and montmorillonite. The swelling properties of the PMCP was studied under harsh reservoir conditions as a function of the aging time to determine the effect of rubbers and HM. The toughness of the optimal particle was investigated by a maximum pressure method followed by core experiments to evaluate the injection and profile improvement performance. The data indicated that PMCP-4 containing the rubber of nitrile butadiene rubber and HM showed advanced properties, such as the swelling ratio, heat resistance, salinity tolerance, and water retention, compared to the other PMCPs. Moreover, the PCMP also exhibited superior toughness, injectivity, and profile control ability. Therefore, PMCP-4 is a promising profile control agent, especially in fractured formations with harsh conditions. (C) 2016 Wiley Periodicals, Inc.
