摘要

作者以T.A.Cross高分辨率层序地层理论与分析技术为指导,通过岩心、钻井资料的综合研究,结合地震资料,对松辽盆地北部泰康—西超地区青山口组(青二、三段)—姚家组—嫩江组(嫩一段)进行了高分辨率层序界面的识别与中期/短期旋回的划分,共识别出13个有时间地层对比意义的界面,包括6个层序界面(基准面下降到上升的转换面)和7个湖泛面(基准面上升到下降的转换面)。另外,还详细阐述了层序特征,并分析了研究区的层序地层模式。这对于寻找非构造气藏具有重要的指导意义。
This paper focused on the application of high-resolution sequence stratigraphy to the formations,i.e., the second and the third sections of the Qingshankou-Yaojia Formation and the first section of the Nenjiang Formation in Taikang-Xichao area of the North Songliao Basin. Based on the comprehensive study of logging, drilling and seismic information, two scales of stratigraphic cycles (short-term and intermediate-term) can be recognized in the study area. The formations were divided into thirteen chronostratigraphic boundaries, including six sequence boundaries, which were the transformation from base-level fall to base-level rise, and seven lake-flood surfaces, which were the transformation from base-level rise to base-level fall. Then, features of these sequences were described detailed and sequence stratigraphical patterns were analyzed. This will be of guide significance for the discovery of non-structural reservoirs.
