摘要
岩心酸化流动模拟试验是室内筛选评价工作液体系和注液程序的有效方法。通过短、长岩心实验, 对比评价了常规土酸(12％HCl+3％HF)和缓速酸对大庆外围东部葡萄花油层高含长石储层岩心的酸岩反应情况。 表明长岩心酸化流动试验能更好地模拟现场酸化的酸／岩反应过程,是优选酸液体系和优化设计的最佳模拟方法。
Core flow simulation test is a kind of effective method to screen out and evaluate the working fluid system and operational procedure. This paper compared the acidification results of conventional mud - acid and retarded acid for both short and long cores from Putaohua oil - bearing formation . It shows long core acidizing flow simulation test can better simulate the reaction between acid and rock on - site, and it is more suitable for acidizing fluid system selection and optimizing design.
