摘　　要：针对成熟阶段的油页岩,提出了一种评价油页岩微小孔隙中含油率的方法。应用测井资料,定量求取油页岩各组分的体积含量,得到较为精确的油页岩孔隙度值和泥质含量。通过导电机理的分析,建立油页岩导电模型。利用测井资料确定方程中各参数,对油页岩含油率进行定量评价。实际应用表明,该方法对富含有机质、泥质含量较多的油页岩具有较好的适用性。利用测井资料定量评价油页岩含油率,可有效弥补实验室测样的不足,并为油页岩研究提供有价值的参考资料。Put forward is an oil cut evaluation method for oil shales in minute pore in mature stage. The volume fraetions of each component in the oil shales are calculated quantitatively by u- sing log data, and then obtained are comparatively accurate oil shales porosity and shale content. Oil shales conductivity model is established by analyzing electrical conduction mechanism. And parameters in the conductivity model are determined from log data, so as to quantitatively evaluate oil cut of the oil shales. Practical application shows that this method has better applicability for oil shale rich in organic matter and shale content. Using log data to quantitatively evaluate oil shale＇s oil cut can effectively make up for deficiencies of laboratory test samples, and provide a valuable reference for research on oil shales.
