摘要:
WaxmanSmits模型中交换阳离子当量电导率(B)和泥质砂岩阳离子交换容量(QV)这2个关键参数难以准确求取,是影响该模型在实际储层评价工作中推广应用的主要原因。通过温度对参数B、交换阳离子最大当量电导率(Bmax)这2个参数影响规律的分析,总结出参数B的新算法。提出综合利用常规测井资料、核磁共振测井资料和岩心分析资料计算泥质砂岩所含黏土阳离子交换容量、干黏土体积、干黏土骨架密度以及泥质砂岩总孔隙度的方法,进而计算泥质砂岩储层的阳离子交换容量(QV)。对核磁共振测井资料、常规测井计算泥质含量的应用进行重点研究。研究成果应用于胜利油田多个低电阻率油层区块,通过与岩心分析数据、试油数据的对比检验,应用效果良好。
Abstract:
It is difficult that the shaly sandstone’s cationexchange capacity(QV) and exchangedcation equivalent conductivity(B) in WaxmanSmits model are calculated exactly by well logging data,which is the main reason why the WaxmanSmits model cannot be widely used in practical reservoir evaluation. The law is analyzed how the temperature affects the parameter B and exchangedcation maximum equivalent conductivity(Bmax), from which a new calculation method of parameter B is put forward.Based on the statistic analyses of logging data and core sample data, the conventional log data, nuclear magnetic resonance log data and core sample data are used to calcuate the clay’s cationexchange capacity in shaly sandstone, dry clay volume, dry clay matrix density and shaly sandstone’s total porosity. And then the QV of the clay sandstone reservoir is calculated. Especially, studied are applications of the nuclear magnetic resonance log data and shale volume calculated from conventional log data. The research results are applied to several blocks in Shengli oilfield where there are lower resistivity payzones.The application effect is fine, that is verified by formation testing data and core sample analysis data.
