摘要:
WaxmanSmits模型中交換陽離子當量電導率(B)和泥質砂巖陽離子交換容量(QV)這2個關鍵參數難以準確求取,是影響該模型在實際儲層評價工作中推廣應用的主要原因。通過溫度對參數B、交換陽離子最大當量電導率(Bmax)這2個參數影響規律的分析,總結出參數B的新算法。提出綜合利用常規測井資料、核磁共振測井資料和巖心分析資料計算泥質砂巖所含黏土陽離子交換容量、干黏土體積、干黏土骨架密度以及泥質砂巖總孔隙度的方法,進而計算泥質砂巖儲層的陽離子交換容量(QV)。對核磁共振測井資料、常規測井計算泥質含量的應用進行重點研究。研究成果應用于勝利油田多個低電阻率油層區塊,通過與巖心分析數據、試油數據的對比檢驗,應用效果良好。
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.
