柴西地区新生代构造特征及其对油气成藏的影响的开题报告 摘要： 柴西地区地处西北地区祁连山前缘，是中国西北油气勘探的主要区域之一。本文基于地震资料解释、野外地质观察和前人研究成果，分析了柴西地区新生代构造特征及其对油气成藏的影响。结果表明，柴西地区自新构造运动以来，经历了复杂的变形和剥蚀作用，形成了一系列断裂、褶皱和逆冲带。这些构造特征对油气成藏具有显著的控制作用。具体表现在以下几个方面：一是断层控制，柴西地区的油气主要分布在一些断层和断层带上，如洪水断层、崆峒山断层等；二是褶皱控制，柴西地区的油气主要分布在旋回状褶皱和背斜中部；三是逆冲带控制，柴西地区的油气主要分布在逆冲带的褶皱中部和下部。 关键词：柴西地区；新生代构造特征；油气成藏；断层控制；褶皱控制；逆冲带控制 Abstract: Located in the front of Qilian Mountains in the northwest region of China, the Chaixi area is one of the main areas for oil and gas exploration in northwest China. Based on seismic data interpretation, field geological observation, and previous research results, this paper analyzes the new tectonic features of Chaixi area and their influence on oil and gas accumulation. The results show that since the tectonic movement in the Chaixi area, a series of faults, folds, and thrusts have been formed through complex deformation and erosion. These structural characteristics have significant control on oil and gas accumulation, mainly manifested in the following aspects: First, fault control. The oil and gas in Chaixi area are mainly distributed in some faults and fault zones, such as Hongshui fault, Kongtongshan fault, and so on. Secondly, fold control. Oil and gas in the Chaixi area are mainly distributed in the middle of the anticlines and recumbent folds. Thirdly, thrust belt control. Oil and gas in the Chaixi area are mainly distributed in the middle and lower parts of the folds in the thrust belt. Keywords: Chaixi area; new tectonic features; oil and gas accumulation; fault control; fold control; thrust belt control.
