【摘要】 近年来的研究表明,我国西北地区含油气盆地在中、新生代发生了构造反转,这是该区油气地质研究中的一个新的重大科学问题。综述了有关西北地区含油气盆地构造反转的研究概况、研究进展及有关盆地的基本特征;指出西北地区含油气盆地中的中小型盆地的伸展结构保存较好,反转构造较为清晰,而大型盆地构造复杂,其前陆地区的构造反转特征相对清晰;据此提出了构造反转盆地的研究思路和主要研究内容,认为反转构造对油气聚集与成藏的控制作用和反转盆地中油气的分布规律是未来研究的核心问题。更多还原

【Abstract】 The recent achievements show that the inversion tectonics on Northwest petroliferous basins in Mesozoic-Cenozoic occur in Northwest China.It is a scientific field on petroliferous geology.In this context,the overview of the basin inversion tectonics and recent achievement are summarized,and the integrated features are also outlined in the Northwest petroliferous basins.The research results show that the extensional tectonics is little damaged and inversion tectonic is comparatively distinct in the moderate and small-scale basins,whereas the tectonic is complicated and inversion tectonic on foreland area is relatively clear in the large-scale basins.The research thoughts and contents about inversion tectonics are pointed out,in which the key question is the control factor of inversion tectonics to oil and gas accumulation and preservation,and distribution of oil and gas in the inversion tectonics basins.更多还原
