摘　　要：港北地区明化镇组砂体厚度薄、地震反射弱、横向变化快的特点造成了储层精细预测难度加大,为此开展了一种基于多元线性回归属性的储层预测技术研究。以该地区邻井钻遇高产含油砂体为依托,结合精细层位标定、井震结合、人工-智能解释、地震属性交会和地震属性融合技术对港北地区G 147井区NmⅡ⁃8小层展布进行精准刻画,总结出适合该类油藏的砂体预测方法,并在砂体低动用区域成功部署了10口产能井,取得了一定的效果,为该井区进一步滚动扩边提供了依据。The sand body of Minghuazhen Formation in Gangbei area has the characteristics of thin thickness,weak seismic reflection and fast lateral change,which makes it difficult to accurately predict the reservoir.Therefore,an application study of attribute prediction technology based on multiple linear regression in thinner oil reservoirs in Gangbei area was carried out.Based on the high⁃yield oil⁃bearing sand bodies encountered by the adjacent wells in this area,and combined with fine horizon calibration,well and earthquake combination,artificial intelligence interpretation technology,attribute intersection technology,seismic attribute fusion and other technologies,the distribution of G 147 well NmⅡ⁃8 layer in Gangbei area is accurately characterized,and the sand body prediction method suitable for this type of reservoir is summarized.Ten production wells have been successfully deployed in the low production area of sand body,providing geological basis for rolling exploration in this area.
