用测井资料确定储层三孔隙组分的理论与方法

Log Interpretation Theory and Method to Evaluate Three Pore Components in Hydrocarbon Reservoir Formation

分析了岩石的孔隙和孔隙结构与岩石的成分尤其是泥质和粘土之间的密切联系,并从常规测井、核磁测井反映的孔隙度、泥质含量等参数入手,研究建立了常规测井资料划分三种孔隙组分的理论和实现方法,结合实际测井资料,对这些方法进行了检验。实例表明,根据该理论和方法确定的储层的三孔隙组分——粘土水孔隙、微孔隙水孔隙以及自由水孔隙组分可以取得较好的效果。

The close relationship between reservoir formation s pore structure and its mineral components is interpreted here.Using many parameters such as porosity,shale volume and some others acquired from conventional well logs and NMR log,a three-pore-components evaluation theory and its interpretation methods were established based on conventional well log.These methods were tested by use of practical log data collected from several wells.It was proved that this theory and its interpretation methods can give comp...
