一、引言相对埋深大于2500m以下的中深层油藏评价开发而言,浅层油藏评价、开发带来的经济效益是不言而喻的。但由于受地震资料品质和研究技术的限制,使浅层油藏的评价、开发一直停滞不前。为有效地评价、开发此类油藏,本文提出了以三维可视化解释和多属性分析为核心的河道立体 I. INTRODUCTION As far as the evaluation of medium-deep reservoirs with relative buried depth greater than 2500m is concerned, the economic benefits of shallow reservoir evaluation and development are self-evident. However, the evaluation and development of shallow reservoirs have been stagnant due to the limitations of seismic data quality and research techniques. In order to effectively evaluate and develop such reservoirs, this paper presents three-dimensional visual interpretation and multi-attribute analysis as the core of the river three-dimensional
