将GIS技术引入含油气盆地研究中,重建了松辽盆地北部登娄库组底古构造格局,分析了登娄库组底的古构造演化史。研究表明,登娄库组底构造格局具有定型早,继承性发育的特点,姚家期及其以后的构造活动对登娄库组底构造面貌具有一定的改造作用,这种古构造演化格局有利于坳陷区烃源岩的保存和热演化及隆起区继承性构造的发育与天然气成藏。
The GIS technology was introduced into the study of petroliferous basins. The structure of the end-palaeo-structure of Denglouku Formation in the northern part of Songliao Basin was reconstructed. The paleo-tectonic evolution of Denglouku Group was analyzed. The study shows that the structure pattern of Denglouku Formation has the characteristics of stereotyped early and inherited development. The Yaojia period and its tectonic activities have a certain remodeling effect on the basement structure of Denglouku Formation. The paleotectonic evolution pattern is favorable for the depression Preservation and Thermal Evolution of Source Rocks in Subsidence Area and Development of Successional Structures in Uplift and Gas Accumulation.
