摘要
辽河探区地层水水型以NaHCO3为标志,确定地层是否出水主要根据HCO3-含量的大小,应用水力射流泵排液技术排液则存在水性难以落实的难题。提出用HCO3-含量随排液时间变化曲线特征判断地层是否出水的方法,有效地缩短排液周期降低施工成本。
Formation water at Liaohe developing region takes NaHCO3 as symb ol. It is from big or small number of HCO3-1 containment to determine if producing form ation or not. So, it is difficult to discern water property from tech of flowing back with hydraulic pump. The method according to curve feature of HCO3-1 conta inment with flowing back time is suggested which shortens unflowing cycle and lows operat ing cost at effectively.
