摘要
在分析红旗凹陷的构造、断裂、烃源岩演化、油气成藏等特征基础上,通过恢复凹陷各期的盆地原型,认为红旗凹陷在形成与演化过程中经历了多次构造变革作用,相对于原型盆地,现今残余盆地构造格局发生较大的变化。研究认为:红旗凹陷沉积中心和沉降中心的变化表现为“跷跷板”式演化,即塔木兰沟组—南屯组沉积时期表现为东深西浅的格局,南屯组末期的构造改造使盆地沉降中心向西偏移,大磨拐河组—伊敏组沉积时期表现为西深东浅的格局,伊敏末期凹陷整体抬升,东部剥蚀严重,整体表现为西深东浅的格局定型;铜钵庙组—南屯组是红旗凹陷主要的生油层和储集层发育层段,红旗凹陷的盆地原型不仅控制了烃源岩的形成和演化,还对油气成藏过程起着至关重要的作用。
On the basis of the characteristics of the structure,fault,source rock evolution,hydrocarbon accumulation and so on,with the help of the recovered prototype basin in each stage of the sag,many times of the structure changes have taken place in the processes of the generation and evolution of Hongqi Sag,corresponding to the prototype basin,a great change of the structural framework has occurred for the nowadays residual basin.The studies show that the changes of the sedimentary and setting centers of Hongqi Sag are shown as“Seesaw-type”evolution i.e.the framework which was deep in the east and shallow in the west presented in the sedimentary stages from Tamulangou Formation to Nantun Formation,the tectonic reform at the late stage of Nantun Formation migrated westward for the setting center,the framework which was deep in the west and shallow in the east presented in the sedimentary stages from Damoguaihe Formation to Yimin Formation,the sag was uplift as a whole and intensely eroded in the late period of Yimin Formation sedimentation,and then the tectonic framework was shown as the stated above for the whole;Tongbomiao-Nantun Formations are the main oil-generating layers and reservoirs in Hongqi Sag,the prototype basin in Hongqi Sag not only controls the generation and evolution of the source rocks,but also plays the vital role in the process of the hydrocarbon accumulation.
