摘要:
束縛水飽和度是儲層含油氣性識別、水淹層識別、儲量參數評價的關鍵參數,通常采用巖心巖石物理實驗獲取。為利用測井資料獲取較為準確的束縛水飽和度,以元素測井為基礎,通過k_Lambda滲透率模型計算儲層滲透率,進而結合Coates-Timur模型,通過公式推導得到束縛水飽和度計算模型,利用巖心實驗數據采用多元線性回歸法標定模型參數,使得模型具有普遍適用性,實現測井資料束縛水飽和度精確計算。應用效果表明,該方法計算的束縛水飽和度在渤海油田復雜巖性飽和度評價、水淹層評價、低電阻率油層飽和度評價中取得了較好應用效果。
Abstract:
Bound water saturation is an important indicator for identifying oil layers, water-flooded layers and evaluating reserves. It is usually estimated through core petrophysics experiments. In order to obtain more accurate bound water saturation with logging data, this paper firstly uses a k_lambda permeability model based on ECS to calculate reservoir permeability, then estalishes a bound water saturation model by considering the Coates-Timur model, and finally calibrates the model parameters with core experimental data by the multivariate linear regression method to make it universal and estimate accurate bound water saturation based on logging data. Applications show that the bound water saturation calculated by the new method is satisfactory in evaluating the saturation of complex lithologic reservoirs and low-resistivity oil layers, and water flooded layers in Bohai oilfiedl.
