摘　　要：地质统计学反演融合随机建模与地震确定性反演,有效地综合了地质、测井和原始地震数据,该方法可以有效避开常规确定性反演遇到的数据正则化问题,同时通过地质统计学反演得到的属性体,其垂向分辨率不仅可以接近井资料,同时横向分辨率也得到较好地保障,并且相对于确定性反演而言,具有较高的抗噪性能。通过该方法在中原油田东濮老区的应用,证实利用地质统计学反演能有效地提高砂泥岩薄互层的刻画能力。The inversion of geostatistics combination with random model-building with deterministic seismic inversion,and effectively integrates the geological,well logging and original seismic data.This technique avoids data regularization problem of conventional deterministic inversion,meanwhile,its product attribute volumes not only have vertical resolution approaching to logging data,but also guarantee its transversely continuity.At the same time,this method has high noise-resistance comparing to deterministic inversion.The appliance in Dongpu reservoir verified geostatistical inversion method can increase the ability of describing sand-shale thin interbed.
