【摘要】 丽水-椒江凹陷位于东海陆架盆地台北坳陷西部,其沉降过程经历了裂陷期、坳陷期、抬升期及区域沉降期4个阶段。盆地构造样式复杂,具有半地堑-地堑式结构并存、频繁变化等特征,断裂构造发育,主要有铲式、坡坪式、多米诺式、"Y"型、阶梯状、地垒和地堑等断裂构造组合。构造活动有效控制油气圈闭的形成,灵峰构造带(潜山构造带)、丽水西次凹中央反转背斜构造带、丽水西次凹屋脊断块构造带、椒江凹陷中部断块半背斜构造带为该区未来勘探的有利区带。更多还原

【Abstract】 The Lishui-Jiaojiang sag locates at Western Taibei depression,the East China Sea Shelf Basin.It has undergone the four stages of subsidence processes,which are rifting,sinking,uplifting and regional subsidence phases.The structural styles are complex.Graben and half-graben structures coexisted and changed frequently.There are many fault structures,the main types are listric fault,ramp-flat fault,domino fault,Y-type fault,step fault,horst,graben,and so on.The tectonic activity controlled the formation of the hydrocarbon-bearing traps.The Lingfeng tectonic belt,reversal anticline and roof-fault tectonic belts of West Lishui sag,central half-anticline tectonic belt of Jiaojiang sag are the hopeful exploration areas.更多还原
