摘　　要：为了在姬塬油田G55区块滚动勘探开发阶段更高效地进行小层砂体展布预测，探索性地提出一种在单砂层上预测小层砂体的方法。应用高分辨率层序地层学原理，将长21^2层划分为半个短期基准面旋回，3个超短期基准面旋回——长21^2-1、长21^2-2和长21^2-3通过3个超短期基准面旋回内的砂体展布规律研究，预测出该区长21^2小层砂体展布及沉积微相，证明该方法能够较好地指导该区的产能建设。In order to effectively predict sublayer sandbody extension in the process of rolling exploration and development in Block G55 of Jiyuan Oilfield, a method is provided to predict sublayer sandbodies in single sand layer. Based on the theory of high-resolution sequence stratigraphy, Chang 21^2 layer is divided into half short-term basal level cycle, and 3 super-short term basal level cycles-Chang 21^2- 1, Chang 21^2-2 and Chang 21^2-3. Then, according to the study on sandbody extension rules in 3 super-term basal level cycles, sandbody extension and sedi- mentary microfacies of Chang 21 ： sublayer in this area are predicted, proving that this method can guide production construction of this area.
