目前我国东部的石油勘探工作已进入精细勘探阶段,如何确定陆相地层中薄储层的空间展布规律及其性质已成为一个亟待解决的问题,由于我国东部的绝大多数中、新生代陆相含油盆地大都以薄层砂、泥岩沉积为主,夹有少量薄层碳酸盐岩、页岩及膏盐层,地层岩性和厚度横向变化均较大,而且这些地层的厚度远远低于常规地震勘探的垂向分辨率,因此,从理论上研究沙泥岩薄互层地震反射特征、薄互层组内的单层厚度、子结构厚度、互层组内层数、入射子波类型、主频、采样率等各种因素对反射波特征的影响,将对我们定性或定量求取薄互层组中各单层厚度或薄层组的厚度、预测薄储层的空间展布规律有一定的理论和现实意义。

According to the analysis of features of the key outcrop sequence stratigraphy, build the sequence frame, through the section comparison, and the study of feature of the 5 key outcrops, then it can be concluded that, conglomerate on the denudation plane or the other contrastive sediment are the main features surrounding the bottom border of the sequence. In the foreland basin sediment environment, the transilient group of mud rock and sandstone are the main sediment features of low-stand system tract. Thick mud rock and sandstone interbedded is the chief component of transgressive system tract, sometimes together with thick turbidity current sandstone; High-stand system tract is composed by the combination of mud rock and sandstone interbedded, with the progradation as its main style. Maximum flooding surface Sediment are usually mudstone, and the thickness is different from each other.
