岩相渗透率预测由于缺少直接测量工具而一直是地层评价面临的难题。所述方法可视为一种确认已知相关系数的简单工具,或视为未取心井强有力的预测方法。应用之一,显然是确定岩相。岩相分类用于井相关分析,刘建立油气田三维模型很重要。应用之二是计算渗透率。认识渗透率对确定完井方案和综合生产率十分重要。新技术将误差量化,并结合测量数据用之,从而改进了预测效果。该方法在几个油田应用后,获得了比传统技术更好的渗透率估算值。此外,该方法采用基本测井数据如伽玛射线和孔隙度,而不依赖于测井新技术。
Lithologic permeability prediction has been a challenge for formation evaluation due to the lack of direct measurement tools. The method can be viewed as a simple tool to confirm known correlation coefficients or as a powerful prediction method for non-cased wells. One of the applications, apparently to determine lithofacies. The classification of lithofacies is used for well correlation analysis. It is very important that Liu Jianli’s three-dimensional model of oil and gas field is established. The second application is to calculate permeability. Recognizing penetration is important in determining completion plans and overall productivity. The new technique quantifies the error and uses it in combination with the measurement data to improve the prediction. After several fields have been applied, this method yields better estimates of permeability than conventional techniques. In addition, this method uses basic well logging data such as gamma ray and porosity without relying on new logging technologies.
