摘要
文章讨论了磺甲基间苯二酚一甲醛(SMRF)成胶液在Berea岩心内的驱替过程中,磺甲基间苯二酚(SMR)的紫外光谱测定。SMR的紫外光谱与溶液的pH和放置时间有关,由于Berea岩心的作用,本实验条件下流出液的pH较冲洗液的pH高,为了提高测定的准确性,建议在SMR溶液和驱替试验的流出液中加入适量缓冲液,使其呈酸性,然后再进行紫外光谱测定,原试样中SMR的含量由所得的紫外吸收值和试样的浓度变化折算得到。
In this paper,the ultraviolet Spectrum of sulfomethylated resorcinol(SMR)during the development of a novel EOR polymer, aqueou6w sulfomethylated resorcinolformaldehyde(SMRF) gel-forming solution,has been determined. The ultraviolet spec-trum of SMR was relative to pH and preparation time of its solution. Due to the action ofBerea core,the effluent had higher pH than flushed solution in the experimental condition.To improve the ilccuracy, it was suggested that the samples whether SMR solution or theeffluent during displacement experiment were added with adequate buffer and becomeacidic before determination of their ultraviolet spectra. SMR content in the original wasconverted from ultraviolet absorption value obtained and the concentration change of thesample.
