北黄海盆地东部坳陷断裂构造分析
|
摘要
北黄海盆地是我国海域勘探程度较低的含油气盆地,断裂构造极其发育并对盆地的沉积构造演化及油气成藏具有重要控制作用。通过对北黄海盆地东部坳陷最新三维地震资料精细构造解释,系统研究了该区的断裂构造类型、特征及其成因演化。断裂构造类型按运动学特征可分为正断层、逆断层、扭动断层和反转断层;按断层级别与规模可分为一级控盆断层、二级控凹断层、三级控带断层、四级控圈断层和五级层内或层间小断层。研究区主要发育了北西向、北东向、近南北向和近东西向4组断层,平面组合样式有平行式、斜交式、雁列式、斜列式等;断裂剖面形态有犁式、座椅式、坡坪式、平直式等,剖面组合样式包括伸展性质的地堑、地垒、"Y"字形、反"Y"字形、复合"Y"字形、同向断阶、反向断阶、"入"字形、羽状、帚状、树枝状、梳状和扭动性质的似花状、半花状以及挤压性质的叠瓦状。中-新生代断裂活动主要有6个地质时期:1中侏罗世-晚侏罗世伸展活动;2侏罗纪末期挤压反转;3早白垩世弱伸展活动;4始新世-早渐新世伸展活动;5晚渐新世伸展活动;6新近纪弱伸展活动。北黄海盆地东部坳陷中、新生代构造演化经历了多期伸展-反转挤压(隆升)构造旋回,上述断裂分期差异活动是周边板块运动和深部地质作用双重控制的结果。
Fault structures in the North Yellow Sea Basin are extremely developed and very complex,which affect significantly the tectonic and sedimentary evolution as well as hydrocarbon accumulation of the basin.According to the detailed structure interpretation of the latest 3Dseismic data of the Eastern Depression in this basin,this paper studies the types,characteristics and evolution of fault structures systematically.Based on the kinematic characteristics,fault structure types can be divided into normal faults,reverse faults,twisting faults and inversion faults;According to the level and scale of the faults,they can be classified into the five-level faults.The trending of these faults in plane mainly includes north-western,north-eastern,approximately north-southern and east-western.Combination styles in plane include parallel type,oblique-contact type,the echelon and inclined column type.Fault forms in sections include plough type,seat type,slope flat type,straight type,etc.In seismic sections,they develop stretching properties of graben,horst, " Y" glyph,reverse " Y" glyph,complex " Y" glyph,synthetic fault terrace,antithetic fault terrace, " conjugate" shaped,broom,comb,dendritic,pinnate,approximately flowerstructure,and half flower-structure and imbricate with pressing properties.The fault activities during Mesozoic-Cenozoic can be mainly classified into six geological periods:1Middle Jurassic to Late Jurassic with extensional activities,2Late Jurassic with compression and inversion activities,3Early Cretaceous with weak extensional activities,4Eocene to Early Oligocene with extensional activities,5Late Oligocene with extensional activities,and6 Neogene with weak extensional activities.During the Mesozoic-Cenozoic,the tectonic evolution of the Eastern Depression in the North Yellow Sea Basin experienced several tectonic cycles of extension-compression and inversion(uplift),and so the various activities of faults in the Eastern Depression are the results of the control actions of the surrounding plates' movements and the geological process in depth.
