摘要: 本文根据钻井、测井、录井、地震等资料，对罗东地区沙四上亚段砂砾岩体储层展布规律开展研究，明确了砂砾岩扇体发育范围，应用地质统计学反演技术划分了砂砾岩扇体期次，基于相控机器学习地震属性融合储层预测方法对有利储层进行了预测，明确了有利储层的分布范围，为罗东地区砂砾岩扇体的进一步勘探提供了理论指导。

Abstract: Based on data from drilling, logging, mud logging, and seismic surveys, this study investigates the distribution patterns of glutenite reservoirs in the upper Es4 submember of the Luodong area. The developmental extent of glutenite bodies has been delineated, and the stages of these fans have been classified using geostatistical inversion technology. By employing a facies-controlled machine learning seismic attribute fusion method for reservoir prediction, favorable reservoirs have been identified, and their distribution range has been clarified. This research provides theoretical guidance for further exploration of glutenite bodies in the Luodong area.
