摘要
从分析钻孔中自然电场的形成机理出发,介绍了自然电位测井曲线形态及其在渗透性地层中的曲线响应特征,并对自然电位与砂岩中泥质含量的关系进行了讨论,在此基础上提出了利用自然电位曲线计算砂岩中泥质含量的方法及自然电位曲线在实际应用中应注意的事项。
Start from spontaneous electric field formation mechanics in boreholes,introduced spontaneous potential logging curve configuration and its response characteristics in permeable strata,discussed relations between spontaneous potential and argillaceous content in sandstone.On this basis,put forward a method to estimate argillaceous content in sandstone by using spontaneous potential curves,and matters needing attention in practical application.
