摘要(Abstract)：

应用变异函数探讨了砂体的定量预测问题。通过对北二东密井网试验区不同类型砂体、不同井网密度砂岩厚度的预测 ,检验了此方法的精度 (为 70 %左右 )。在原方法的基础上 ,通过对预测精度的分析并结合精细地质研究进一步完善了该方法 ,提出二次建模法并应用于北二东西块聚驱井的砂岩厚度预测中 ,预测精度可提高 5 %以上 ,从而说明应用变异函数研究砂体的定量预测问题具有可借鉴性 ,可以为今后新井调整厚度的预测及砂体描述提供依据
This paper applies variable function to discuss on quantitive sand body prediction. the method , s precision(70%)was proved through predicting sandstone thickness of different sand body and well pattern density of Beierdong dense well pattern testing area. On the basis of the method , through the analysis of the predicting precision and combining the fine geology research, the method was further perfected, put forward secondary modeling ,and conducted sandstone thickness prediction of the west block in Beierdong polymer driving wells, the result shows that predicting precision can increase by 5%,thereby the interpretation that applies variable function to study sand body quantitative prediction has reference value, this method can be helpful for prediction of new well adjusting thickness and sand body describing.
