Preparation and Properties of Slow-release Organic Acid Micro-emulsion with High Efficient Plugging Removal

  • 摘要: 针对油田常用酸化方法存在酸液剖面不均匀和二次伤害的问题,优选有机酸和无机酸形成复合酸,优选表面活性剂和助表面活性剂,制备出有机缓释酸微乳液,其最优配方为:AQAS∶AEO=1∶1, 正丁醇∶正辛醇 =1∶1,水相∶油相=3∶7,助表面活性剂︰表面活性剂=1∶2,乙酸∶氢氟酸=4∶1。该体系的泥饼清除率超过85%,在低渗岩心中解堵效果显著,其渗透率恢复值超过100%。
