| 摘 要： | 研究了江汉盆地潜江凹陷东南部地区构造演化、沉积体系类型及其沉积相模式、沉积体系展布及其控制因素,分析认为潜江凹陷东南部地区新沟嘴组下段主要发育三角洲-咸水湖泊沉积体系,新沟嘴组下段沉积之前发育的深大断裂、继承性古隆起对新沟嘴组下段沉积相展布具有明显的控制作用。沉积微相包括水下分流河道、河口沙坝、席状砂、滨浅湖滩沙、沙坝等多种微相。物源供给和砂体展布都有两支,分别是汉水水系和汉川水系。由于对储层展布认识不清,致使油气的进一步勘探受到了制约。因此,开展沉积相控制下的储层展布特征研究,对该区油气勘探具有重要的意义。

| Abstract: | According to the study on the history of structural evolution in southeast of Qianjiang sag in Jianghan Basin,the depositional system and distribution,the patterns of sedimentary facies and the controlling factors,it is concluded that the delta-saline water lake depositional system is in predominance development in lower Xingouzui formation of southeastern Qianjiang sag in Jianghan Basin.It was the deep fracture and palaeouplift developed before deposition of lower Xingouzui formation that visibly controlled the distribution of lower Xingouzui formation.The two controlling factors of deep fracture and continuous palaeouplift are primary in this district.There are multiple sedimentary microfacies including :underwater distributary channel,sand sheet,nearshore sand and sand bar.The supplementary and sand distribution derived from Hanshui branch and Hanchuan branch.The structural evolution of southeastern Qianjiang sag primarily experienced three sedimentary cycles and six evolution periods.The misunderstanding of reservoir distribution led to the restriction of further exploration.Therefore,it is meaningful to carry out the study on distribution features of the oil reservoir layer controlled by the sedimentary facies for further oil exploration in this district. |
