对济阳坳陷大量高分辨率三维地震资料的解释和分析,利用反转构造在地震剖面上的识别标志和不整合的发育特征等方法,确定济阳坳陷东营组沉积末期正反转构造的分布范围以及相应的反转构造样式。对坳陷正反转构造成因机制研究表明,东营组沉积末期济阳坳陷构造应力为NEE-SWW双向强挤压应力和NW-SE双向拉张应力的叠合,且构造反转的选择性造成了正反转构造样式的差异性。对坳陷正反转构造的认识可以为济阳坳陷油气勘探提供地质依据。
The interpretation and analysis of a large number of high-resolution 3D seismic data in the Jiyang Depression are carried out to determine the positive and negative inversion structures of the Dongying Formation at the end of the deposition in Jiyang Depression using the identification sign of the inverted structure on the seismic profile and the developmental features of the unconformity The distribution of the scope and the corresponding inverted structure style. The study on the genetic mechanism of positive and negative inversion tectonics shows that the tectonic stress in the Jiyang depression at the sedimentation stage of Dongying Formation is the superposition of NEE-SWW bidirectional compressive stress and NW-SE tensile stress, and the structural inversion selectivity Resulting in the difference between positive and negative structural style. The understanding of the normal and reverse tectonics in the depression can provide the geological basis for the exploration of oil and gas in the Jiyang Depression.
