| 摘 要： | 泛克里格法是一种非平稳的地质统计学方法，在应用其进行井间砂体预测时，以井点处测井资料解释的砂岩厚度为控制条件．通过分析不同方向砂岩厚度的变化趋势．建立反映各个方向砂体变化剧烈程度的漂移多项式表达式，结合变差函数的计算．在求解泛克里格方程组的基础上．给漂移多项式和已知变量赋予最佳的权值，可以对井间砂体的展布进行精确的插值和估计．尤其适合横向变化剧烈的地质变量(如河道砂体的厚度)的估值。该方法在黄骅坳陷柳赞油田沙三段井间砂体预测中取得了很好的应用效果。图5表4参6 |

| Abstract: | Universal Kriging is an unsteady geostatistical method which is used for predicting sandstone between wells. Conditioned by sandstone thickness interpreted from logging data at well location, Universal Kriging could be used to build drift polynomial expressions reflecting sandstone variety by analysis of sandstone thickness variation in different directions. The estimate value of sandstone thickness between wells from Universal Kriging could be much precise and is more coincident with geological rules. Excellent effect is got in the prediction of sandstone between wells by Universal Kriging in Member 3 of Shahejie Formation, Liuzan Oilfield. |
| Keywords: | Universal Kriging geological model sandstone prediction Liuzan Oilfield |
