摘　　要：松辽盆地三肇凹陷东部榆东地区扶杨油层具有较大资源潜力,为了对该区扶杨油层砂体发育展布特征进行研究,采用地质统计学反演基本原理,按照子波提取及井震标定、建立低频背景模型、约束稀疏脉冲反演和地质统计学反演参数测试的步骤,实现了对扶杨油层砂体分布特征的预测。通过趋势分析和符合率验证均表明地质统计学反演方法对榆东地区扶杨油层砂体预测具有较高的适用性,对于指导该区下一步勘探提供重要的支持作用。Fuyang Formations in Yudong area of Sanzhao sag in Songliao basin has great resource potential. In order to study the sand body development and distribution characteristics of Fuyang oil layer in this area, the basic principle of geostatistics inversion is adopted. According to the steps of wavelet extraction and well seismic calibration, establishment of low-frequency background model, constrained sparse pulse inversion and geostatistical inversion parameter test, prediction of sand body distribution in Fuyang reservoir is realized. Through trend analysis and coincidence rate verification, it shows that geostatistical inversion method has high applicability for sand body prediction of Fuyang reservoir in Yudong area, and provides important support for guiding the next exploration in this area.
