There are massive salt dome s of great thickness,which ranges from several dozen meters to 3,700 meters,in pre-salt Carboniferous carbonate reservoirs of the Pre-Caspian Basin.

由于盐丘和围岩间存在巨大的速度差异，因此导致盐体本身和下伏地层在常规地震资料中出现反射品质降低、构造失真、畸变(如盐下石炭系目的层地震反射层在盐丘部位出现构造上拉现象)，消除盐层的影响是含盐油气盆地勘探的重要课题。

So, researching the influence to reflection wave features made by the factors, such as sand and mud thin-bedding seismic reflection feature, the thickness of single layer in the thin-bedding group, the thickness of subroutine structure, the number of layers in the thin-bedding group, type of incident wavelet, main frequency, sampling rated has the moment current significance and theoretical significance in the qualitative or quantitative seeking of single layer's thickness or thin layer group's thickness in the thin-bedding and forecast of the space distribution laws of thin reservoirs.

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。
