【摘要】 通过对南华北盆地典型地质剖面和地震剖面的研究,对盆地的构造样式进行分析和归类,厘定出5种主要构造样式,即逆冲推覆、伸展、走滑、反转和重力滑脱。在此基础上,由点及面地深入研究了该地区盆地性质和区域构造背景。探讨了华北盆地南部构造样式与油气聚集的关系,勘探实践表明油气大多集中在伸展构造样式的圈闭中,同时也要加强逆冲推覆和反转构造样式的圈闭研究。更多还原

【Abstract】 Through the study of typical geologic and seismic sections in the southern North China Basin,the structural styles are analyzed and classified.There are 5 main structural styles: thrust,extension,strike-slip,inversion and gravity decollement.Based on the structural style analysis,the basin property and regional tectonic background of the southern North China Basin are discussed.The relation between hydrocarbon accumulation and structural style of the southern North China Basin are also discussed.Exploration practices have indicated that,petroleum usually accumulates in extensional traps,and thrust and inversion traps also deserve attention.更多还原
