| 摘 要： | 饶阳凹陷沙河街组主要为砾岩、含砾砂岩、砂岩、粉砂岩和泥岩构成的一套碎屑岩组合,根据沉积特征将其确定为辫状河三角洲沉积.该沉积三层结构清楚,由下而上出现前辫状河三角洲亚相、辫状河三角洲前缘亚相及辫状河三角洲平原亚相,呈明显的进积层序,主要发育辫状河道、洪泛平原、水下分流河道、水下分流河道间、河口坝和席状砂等沉积微相.据其岩性、沉积构造、粒度及沉积序列等特征,建立了沉积模式.从岩性特征看,沙河街组辫状河三角洲沉积物具有分布较广、储集物性较好的特点,辫状河三角洲前缘水下分流河道砂体和河口坝砂体储集物性最好,是下一步勘探的有利目标. |

| Abstract: | The Shahejie Formation in Raoyang Sag mainly comprises a set of terrigenous clastics such as conglomerate,conglomeratic sandstone,sandstone,siltstone and mudstone. A study of sedimentary characteristics led to the recognition of typical braided river delta deposition,whose characteristics are distinct and significantly different from other types of deltas resulting from river tractive current sedimentation which are generally controlled by torrential flood and seem to be seasonal sediments. The most notable... |
