摘　　要：运用变差函数研究苏里格气田69口井的区域储层砂体的规模预测,并与常规插值方法作的等厚图及剖面图进行了对比。研究表明该方法可以很好地表征储集砂体的非均质性,可较为精确地对储层进行规模预测。Delta braided stream sandbody has tremendous changes owing to the side move of watercourse and the variety ofdiara. The traditional statistical method can not describe the variable well such as the sandbody scale and reservoir character which both structural and stochastic. The article introduces the study on the dimension prediction of 66 wells sandbody in Sulige gas field which apply variogram of geostatistics. It contrasts waited thick diagram with cross section by normal regulations. It shows that it provide the reservoir heterogeneity and carry on accurate dimension prediction of sand bodyby by this method.
