松辽盆地北部深层断陷沙河子组末期反转构造及对天然气成藏的影响
|
摘要
通过地震剖面解释和平衡剖面分析认为松辽北部断陷期挤压反转构造有三期;总结了沙河子组末期的反转构造样式;并分析了反转构造的平面分布规律及产生的动力学机制;研究认为沙河子组末期反转构造对构造圈闭的形成和天然气生储配置有积极作用。
Through the seismic section interpretation and the balanced cross-section analysis,it is shown that the movement of the compressional inversion structures can be divided into three periods during the faulted period in northern Songliao basin.The inversion tectonic styles are summarized,and the planar distribution and the dynamics mechanism of inversion structures are analysed.It shows that the inversion structures in the late Shahezi stage have a positive effect to the formation of structural traps and the configuration of source-reservoir.
