渤海湾地区前第三系的这种构造样式分布格局可能是印支期华北板块与北部的西伯利亚板块、南部的扬子板块先后闭合碰撞以及燕山中、晚期滨太平洋构造域影响作用不断增强和深部岩石圈的大规模减薄作用的结果。

Results of inversion show that pre-Tertiary deposition in Dongying depression is controlled with westnorth structures. Archaean group is the crystal basement of Dongying depression, which is a north steep and south gentle rift subsidence basin striking from eastnorth to near westeast, and the deepest position is up to 12000 m at the area of Xianhe and Xinzhen. The configuration of Ordovician of lower Palaeozoic system highly inherits that of Archaean group and both have a strong consistency. The configuration of Mesozoic inherits that of lower Palaeozoic system as a whole, but filling and local reconstruction are distinct, and the scope of Dongying depression has obviously decreased.

结果表明，东营凹陷前古近系沉积主要受北西向构造的控制，太古界构成东营凹陷的结晶基底，是一个北东转近东西向的北陡南缓的断陷，最深处位于现河、辛镇一带，可达12000 m；下古生界奥陶系构造具有很强的继承性，其构造格局与太古界有很强的一致性；中生界宏观上继承了下古生界的构造形态，但填平补齐和局部改造比较明显，凹陷范围明显缩小。
