| 摘 要： | 对漠河盆地中侏罗统绣峰组、二十二站组、额木尔河组及开库康组露头剖面详细沉积学研究,查明漠河盆地绣峰组为冲积扇、扇三角洲及湖泊沉积,二十二站组和额木尔河组为辫状河三角洲和湖泊沉积,开库康组为冲积扇、扇三角洲及湖泊沉积,湖底扇和湖泊相在各组均有发育。从绣峰组到开库康组,具有冲积扇-扇三角洲-湖泊—辫状河-辫状河三角洲-湖泊—冲积扇-扇三角洲-湖泊的沉积演化规律。这一沉积演化规律决定了漠河盆地中侏罗统生油气层、储层、盖层均较发育,具有油气勘探潜力。

| Abstract: | The detail sedimentation study of the Middle Jurassic outcrops consisting of Xiufeng,Er-shierzhan,Emuerhe and Kaikukang formations respectively,indicated that alluvial fan,fan delta,braided river delta,lake floor fan and lacustrine facies were developed from Xiufeng to Kaikukang formations in the Middle Jurassic of the Mohe Basin.The alluvial fan and fan delta facies were developed in the Xiufeng formation,the braided river delta in the Ershierzhan and Emuerhe formations,alluvial fan and fan delta in the Kaikukang formation,and lake floor fan and lacustrine facies in all above formations.The sedimentary evolution from Xiufeng to Kaikukang formation was as alluvial fan fan delta lacustrine to braided river braided river delta lacustrine to alluvial fan fan delta lacustrine.Such a sedimentary evolution resulted in the development of source rocks,reservoirs and cap rocks.Therefore,there is petroleum potential in the Middle Jurassic of the Mohe Basin. |
