渭河盆地结构及其油气成藏地质条件
Basin structure and hydrocarbon accumulation conditions of the Weihe Basin
摘要
Abstract
The Weihe Basin, which is located in the southern margin of the Ordos massif, is a Cenozoic fault basin. Understanding the basement structure and tectonic characteristics of this basin are pivotal to guide hydrocarbon ex⁃ploration and resource potential evaluation. In this paper, the basement and tectonic style of the Weihe Basin is studied using regional structural analysis, with comprehensively field geology, drilling, test and geophysical data such as gravity, aeromagnetic, seismic etc. In turn, the hydrocarbon accumulation conditions of this basin are also discussed . The research results show that the pre⁃Cenozoic basement of the Weihe Basin is mainly composed of four different physical partitions. The tectonic style of the Lower Paleozoic basement is mainly strong fold deformation, which is separated by Cenozoic normal faults. The Cenozoic tectonic style of this basin is a half graben, which is controlled by normal faults. Both the pre⁃Cenozoic and the Cenozoic of the Weihe Basin have good natural gas reservoir forming conditions.关键词
