W.hat Does Diagnostic Fracture Injection Testing (DFIT) Mean?
诊断骨折注射检测(DFIT),也称为迷你FRAC,迷你跌倒或数据FRAC是对超低渗透率的压力瞬态测试,以提供有关储层的有价值的信息,以及液压断裂处理参数。
T.he test in effect is a short duration, small volume fracturing operation where small quantities of clear fluid i.e. 2 or 3% of potassium chloride (KCl) water is injected in small quantities to create a fracture before the wellhead is shut-in and pressure is released.
由于向非传统,超低渗透储层的转变,DFIT已被证明是确定储层和FRAC特性的最经济方法。
