摘要: 本文在松辽盆地北部徐家围子芳深9井区构造地质、石油地质及构造应力场分析的基础上,对早白垩世嫩江组末期、晚白垩世明水组末期和现今三个构造时期在营城组火山岩地层中的构造应力场进行了三维有限元数值模拟,进而分析了三维构造应力场在裂缝预测分析中的应用,研究结果与构造地质、石油地质分析结论相一致,对油气勘探开发具有指导意义。

Abstract: On the basis of the analysis of structural geology,petroleum geology and tectonic stress field at Fangsheng 9 drill area of north Songliao basin,three-dimensional tectonic stress fields at the end of Nunjiang Formation of Early Cretaceous,the end of Mingshui Formation of Late Cretaceous and present are simulated respectively,and then we discuss their application to fissure predication.The results have a good agreement to the comprehensive conclusions from structural geology and petroleum geology,and will play a role in hydrocarbon exploration and development in the research region.
