摘要

博兴凹陷位于东营潜断陷西南边缘,是一个形成于中—新生代的断陷盆地,沉积了巨厚的新生代地层。根据收集的历年博兴凹陷内的重力、地震及石油录井资料证实,区内大面积发育泥岩-灰岩-白云岩相地层,其东北部分布小范围的含膏泥岩石膏相和岩盐相地层。岩盐矿赋存于区内沙河街组四段下部。通过初步分析认为博兴凹陷不是一个独立的含盐盆地,它属于东营潜断陷盆地的一部分。
Boxing depression is located in the southwest of Dongying depression sequence,which is formed in Mesozoic-Cenozoic depression basin,and sedimented thick Cenozoic strata.Based on former data of gravimetric,seismic and petroleum logging data,there is a large amount of mudstones,limestone,dolomite facies and polyhalite in the depression area.In addition,small scale gypsum-bearing mudstone and halite facies developed in northeast part of the depression.Halite deposit occurred in the lower part of the fourth section of Shahejie formation.Through primary analysis,it is regarded that Boxing depression is not an independent sedimentary basin.It belongs to Dongying depression sequence.
