从大尺度构造系统上认识松辽盆地,有助于全面审视和重新评价油气成藏的展布规律。通过综合分析认为,松辽地区主要发育内蒙-兴安构造系和滨西太平洋构造系,其次有局域性的纬向构造和经向构造以及北西西向与北北东向共轭断裂构造。并探讨了这些构造的动力学背景。
Understanding the Songliao Basin from a large-scale structural system helps to comprehensively review and re-evaluate the distribution law of hydrocarbon accumulation. Through comprehensive analysis, it is concluded that the Inner Mongolia-Xing’an tectonic system and the western Taixi Pacific structural system are mainly developed in Songliao area, followed by the local latitudinal and meridional structures and the NW-NW and NE-NN faults. The dynamics of these structures are discussed.
