| 摘 要： | 为了预测砂体分布规律与岩性圈闭有利区带，指导下一步勘探，采用微观组分特征、岩石结构、粒度分布特征和沉积微相分析等方法，分析研究了高青砂岩体的沉积模式。研究表明，高青砂岩体的沉积微相有水下分流河道、河口砂坝、前缘席状砂沉积、砂泥互层沉积、前扇三角洲深水湖泊沉积。砂岩体的沉积模式分为三种：下部（G3）属（扇）三角洲水下部分沉积，中部（G2）属三角洲水下部分沉积，但湖泊中心和沉积中心进一步向南东方向迁移，上部（G1）与中部相似，但水下主分流河道以向南南东方向展布为主。根据高青砂体所处的构造位置及砂体与围岩的相互关系，确定了砂岩体的沉积环境为扇三角洲前缘与前扇三角洲。

| Abstract: | This paper is aimed to predict the sandstone distribution and the lithologically favorable petroleum trapping zones through the study on the sedimentation mode in order to guide the petroleum exploration. Methods including component characteristic analysis, petrological structure and grain size analysis and sedimentary microfacies analysis are applied for the study. Five sedimentary microfacies including underground river distributary, debouch bar, frontal sheet sand, sand-shale alternating layer, front fan-delta-deep water lake deposits are identified. The sedimentation mode of the Gaoqing Sandstone Body has been classified into three types. The lower part was formed by the fan-delta underwater sedimentation, the middle part was formed by the fan-delta underwater sedimentation with the center of the lake and sedimentation migrating southeastward, and the upper part was formed similar to the formation of the middle part with the underground river distributary distributing in southeastward. Based on the structural position of the Gaoqing sandstone body and the relationship between the sandstone body and its country rock, it is concluded that the sedimentation environment of the Gaoqing sandstone body is frontal fan-delta and fan-prodeha. |
