低渗透油层表面活性剂胶束溶液驱乳化性能研究
|
摘要
针对当前我国低渗透油藏3次开采的需求,结合当前的表面活性剂的相关理论,构建了一种新型的胶束溶液驱油体系。为制备该驱油体系,以非表面活性剂、阴离子活性剂和两性离子活性作为筛选对象,以异丁醇、乙二醇等作为助表面活性剂,以乳化率和界面张力等作为指标,对其性能进行评价,最终得到磺基甜菜碱4%+异丁醇2%(wt)的驱油体系在驱油效率、乳化性等方面,都有着明显的优势。
A new type of micellar solution flooding system was constructed to meet the demand of tertiary oil recovery of low permeability reservoirs in China. In order to prepare the flooding system, the non-surfactant, anionic surfactants and amphoteric surfactants were screened, the isobutanol and ethylene glycol were used as cosurfactants, and the emulsification rate and interfacial tension were used as indicators to evaluate their performance. Finally, the flooding system of sulfobetaine(4%) and isobutanol(2%)(wt) was obtained. The oil displacement system has obvious advantages in terms of oil displacement efficiency and emulsification.
