根据沉积和生物特征可以确认东营凹陷沙一段中的特殊岩性段沉积在滩坝－泻湖体系内．按构成岩性可将滩坝分为砂质和碳酸盐两类．它们的出现反映了凹陷内沙一期相对湖水位上升速率、供屑速率、气候、沉积基底地形等综合背景条件．在演化上，碳酸盐沉积的全面终止意味着滩坝－泻湖体系的终止，终止的根本原因是相对湖水位较大幅度上升所导致的河流注屑速率下降．该沉积体系被认为是湖进体系域的主要构成部分，而且很可能没有典型凝聚层与之伴生．
Based on the sedimentary and biological characteristics, it can be confirmed that the special lithology in the first member of Shahejie Formation in Dongying Sag is deposited in the dyke-lagoon system. According to the composition of lithology can be divided into two types of sandy beach and carbonate. Their occurrences reflect the comprehensive background conditions such as the rate of rise of relative lakes in the sag, the rate of debris supply, the climate and the topography of sedimentary basement. Evolving, the complete termination of carbonate sedimentation means the termination of the beach dam-lagoon system. The root cause of the termination is the drop in the rate of chip fluffing caused by the relatively large increase of the lake water level. The sedimentary system is thought to be a major component of the lake’s system tract, and probably no typical coacervates are associated with it.
