摘要
为解决灰色理论分析方法在评价和预测储层敏感性过程中有时存在评价结果分辨率不高的问题,改进了灰色理论分析方法的算法,建立了一种新的灰色精细预测熵模型。分别使用原灰色评价模型和改进后的灰色评价熵模型对海拉尔油田的岩心分析资料进行了处理、分析。对比结果表明,利用改进后的灰色评价熵模型进行储层敏感性的预测具有预测精度高、适应性好等优点。
The algorithm of the grey theory was modified to enhance its resolution in evaluating and forecasting the sensitivity of reservoirs.A new grey precise-prediction entropy model was established.Cores from Halaer oilfield were analyzed using the original grey theory and the modified model.The modified model gave a much higher resolution of forecasting results,and found a wider application in the analyses of various cores.
