【摘要】 在论述松辽盆地大庆长垣南部葡萄花背斜的构造特征基础上,分析了葡萄花背斜的构造演化,指出自泉头组沉积以来葡萄花构造主要经历了三次沉降,两次抬升,葡萄花构造主要在嫩江期末和明水期末的两次构造运动中形成。分析了葡萄花构造构造演化对成藏的影响,指出葡萄花构造圈闭条件好,圈闭形成时期与烃源岩大量排烃期配合良好,沿断裂发育的圈闭是油气成藏的有利区。更多还原

【Abstract】 The tectonic features of Putaohua Structure of the south Daqing Placanticline in Songliao Basin is described,and the tectonic evolution of Putaohua Structure is analysed.The result indicates that Putaohua Structure has undergone three time deposition and two time uplift since Quantou period,and Putaohua structure was fixed in the end of Nenjiang period and Minshui Period.Effection on hydrocarbon is analysed and the result shows that the condition of structure traps is well and its matched well with oil generation and expulsion,and the structure traps along the faults are the range of profitability.更多还原
