摘要
酸化作为一项较为成熟的增产技术已经大量的运用于海洋油气开发中。BZ25-1油田沙河街储层在整个BZ25-1油田中占据较大比重。至今为止该油田开展的酸化作业以土酸酸化为主[1],近年来正在逐步开展多氢酸酸液体系实践和研究的工作。本文利用酸化效果试验仪模拟岩芯流动的物理过程,通过大量的试验筛选出最佳酸液配方。
Acidification stimulation have been widely used in offshore oil & gas development.Shahejie reservoir accounts for a large proportion of BZ25-1 offshore oilfield,where soil acid-based acidizing dominates [1].Research and practices of multi-hydrogen acid are carried out in recent years.The physical process of core flow is simulated by acidizing effect tester to select the optimum acid formula.
