【摘要】 本文以十六烷基三甲基氯化铵(CTAC)、柴油、盐酸、乙二醇、丙三醇、邻苯二甲酸氢钾(简称PHP)、溴化钾(KBr)为原料,研制耐高温柴油微乳盐酸新体系。分别考察各体系耐温性能、相行为、耐盐性、缓速反应性能；进一步研究了含部分非水介质微乳盐酸,考察了温度及溶剂对微乳酸热力学函数影响,得到以下结论：1.以CTAC为主表面活性剂,正丁醇、正辛醇为辅助表面活性剂,分别与邻苯二甲酸氢钾和溴化钾形成耐高温的CTAC/PHP和CTAC/KBr柴油微乳盐酸新体系,耐温可达98℃,优于文献报道结果。明确了相行为影响因素,获得了优化的柴油微乳盐酸体系组成。CTAC/PHP和CTAC/KBr柴油微乳盐酸体系耐氯化钙能力分别达180000mg/L和225000mg/L；对大理石的缓速率分别达80.5%和73.5%；对钢片的缓蚀率最高可达77.8%和69.3%,表现出良好的缓速反应性能。2.以CTAC为主表面活性剂,正丁醇、正辛醇为辅助表面活性剂,分别与丙三醇和乙二醇形成两种含部分非水介质的柴油微乳盐酸体系,并优化了体系组成。含部分乙二醇微乳盐酸对大理石的缓速率达88.4%,对钢片的缓蚀率达73.7%；含部分丙三醇微乳酸对大理石的缓速率达88%,对钢片的缓蚀率达72.7%。3.以CTAC为主表面活性剂,正辛醇为助表面活性剂,制备得到柴油微乳盐酸。明确了温度和溶剂对微乳酸热力学函数的影响。本文研究提高了微乳酸耐温能力,为高温低渗透储层深度开采打下良好基础。更多还原

【Abstract】 In this paper, the high temperature tolerance microemulsified acids were prepared by using cethyltrimethylammonium-chloride (CTAC), diesel oil, hydrochloric, ethylene glycol, glycerol, potassium biphthalate (PHP) and potassium bromide (KBr). The high temperature tolerance of microemulsified acid systems were studied. The phase behavior, CaCl2 tolerance and control-released reactivity were investigated. In addition, the effects of temperature and solvents on the thermodynamic parameters of microemulsified hydrochloric acid were investigated. The main conclusions were as follows:1. The CTAC/PHP and CTAC/KBr diesel microemulsified hydrochloric acids which showed good stability at 98℃were obtained by using CTAC as main surfactant, n-butanol and n-octanol as cosurfactant. The factors affecting the phase behavior were confirmed and the optimized diesel microemulsified hydrochloric acid systems were obtained. The CaCl2 tolerance of CTAC/PHP and CTAC/KBr microemulsified acids reached 180000mg/L and 225000mg/L, respectively. The steel corrosion inhibition rates of the CTAC/PHP and CTAC/KBr microemulsified acids were 77.8% and 69.3%, and the marble corrosion inhibition rates were 80.5% and 73.5%.2. The microemulsified hydrochloric acids containing ethylene glycol or glycerol were investigated by using cethyltrimethylammonium-chloride (CTAC) as main surfactant, n-butanol and n-octanol as cosurfactant. The steel corrosion inhibition rate and the marble corrosion inhibition rate of the microemulsified acid containing ethylene glycol were 73.7% and 88.4%, respectively. The steel corrosion inhibition rate and the marble corrosion inhibition rate of the microemulsified acid containing glycerol were 72.7% and 88%, respectively.3. The diesel microemulsified hydrochloric acid was obtained by using cethyltrimethyla-mmonium-chloride(CTAC) as main surfactant and n-octanol as cosurfactant. The effects of temperature and solvents on the thermodynamic parameters of microemulsified hydrochloric acid were studied.The study of this paper improved the temperature tolerance of microemulsified acid and provided basis for the application of microemulsified hydrochloric acid in the field of deeply acidification for low penetrability oil field.更多还原
