At last they have being formed the tectonic framework , after breakup of the volcanic island arcs , subduction , decline and fall of the back - arc basins and arc - microcontinent and arc - arc collision had finished 经过了长期而复杂的微大陆和火山弧的裂解、弧后盆地的消减衰亡及弧陆和弧弧碰撞等构造演化，才最终形成今天所见到的这种构造样式。
The three gorge reservoir , locating at the suture between two arc tectonic belts of daba mountain and bamianshan , has strong structural deformation and versatile structural patterns 摘要通过分析大量资料并结合野外地质工作，对三峡库区的区域构造背景及巴东组的主要构造样式进行了总结，分析了这些地质要素对三峡库区变形斜坡形成和发展的影响。
The tectonic style inside the basin is characterized by occurrence of anticlines from the margins to center of the basin , with two limbs mostly starting from reverse faults , developing a tectonic pattern of two faults sandwiching an uplift 盆地内部的构造样式以自盆地边缘至中心以此形成背斜构造为显著特徵，背斜两翼多发育逆断层，构成“两断夹一隆”的构造格局。
Different tectonic style exists in the upper and lower layers of the yanshanian boundary . the lower layers takes on the tectonic style of thrust fault and nappel . the upper layers hi step positive fault 2 、盆地燕山期构造界面上下不同构造层具有完全不同的构造样式，构造界面下伏构造层呈现冲断褶皱、推覆构造样式，构造界面上覆构造样式为阶梯状正断层，整体呈现“双层”结构型式。
Based on the four geologic structural section ( 2 pieces ne - sw direction , 2 pieces nearly ew direction ) which controlled different structural area and several supplementary profiles and several other auxiliary sections , summarize and analyze the structural style research area . surface structural styles shown on great profiles were discussed in different structural section after continual observation 以野外测制的控制不同构造区的四条地质构造剖面(北东-南西向两条、近东西向两条)及若干辅助剖面为基础，对研究区的构造样式进行了总结和分析。
The regional structure interpretation with 3d seismic data shows that the graben and shied mode faults of the baigezhuang , which developed a series of normal faults which stroked in ne ( nee ) and dipped nw or nw , came into being in the rift development stage of ii act of the bohai bay rift basin in mesozoic and cenozoic and resulted from the protrudent boundary of the basin , i . e . the strike - slip and stretch processes of baigezhuang fault 同时，用三维地震资料进行区域构造解释分析，论述了柏各庄地区的构造样式，是中新生代渤海湾裂谷盆地的幕断陷发育阶段，同时由于盆地内凸起边界?柏各庄断层的走滑兼伸展作用，使柏各庄凸起的中生界形成垒、堑断块群构造样式，发育一系列ne ( nee )向，倾向nw或sw的正断层。
Combined with geologic condition and infrastructure characteristics , balance three great structure profiles which trend sn with balance profile theory , then analyze the structure style , association form and each detachment further , and calculate 30 % shorten after the stratum deformation variant it turns out to be striking detachment in multiple tectonic levels and different structure deformation variant style in different stage , after the discussion of the structure style and relation between infrastructure and suprastructure 结合地表地质情况和深层构造特征，利用平衡剖面原理对三条地质构造剖面进行了平衡，通过平衡后的剖面更好地对剖面所反映出的构造样式、组合形态及各个滑脱面进行分析，并且计算出变形后地层的变形缩短量为30左右。研究区内深浅层构造之间存在着显著的多层次滑脱，且不同层次上构造变形样式各不相同。
The extending major fault has a strike of north - east , controlling the forming of depressions and evolution of sedimentation . the nature of the fault is normal in the early stage . later with the reformation of sliding effect , normal faults are still the main faults , and the plane distribution of the faults occurs sectionally 取得了一系列的研究成果：辽河滩海地区主要有三种构造样式，即伸展构造样式、走滑构造样式及反转构造样式，其中，以伸展构造样式为主，伸展主干断裂走向以北东走向为主，控制凹陷形成和沉积演化，断裂性质早期为正断层，后期经走滑作用改造，至今仍以正断层形式出现，断裂平面展布具有分段性。
This paper , applying sequence stratigraphy , through studying on sedimental faices and running the sedimental model , obtained the reservior ' s distributing feature of the whole depression whose centre is the well ou39 . this work obtained the distribution scenario of ou39 ' s fan - delta ' s sandbody and the favrable - explorating area to afford the evidences for production . it is necessary to give the structural background of the studied area , especially , the concept of the structural style is also important to the study of the development to the deposition and sedimentary system 此论文主要从高分辨率层序地层学、沉积相和沉积体系的研究、构造及成岩作用等诸方面的研究对欧北-大湾地区储层建立了模式，并对主要目的层沙三段不同时期的储层优劣进行了评价，主要包括以下内容： 1 、对欧北-大湾地区的构造背景和构造演化进行了探讨，详细分析了研究区存在的主要构造样式，并说明了构造演化控制层序和沉积体系的形成和展布，构造样式控制着圈闭和油气藏的形成。
This thesis begins with the partition of dynamic system of entrapment , emphasizes the study on entrapment and process , then makes sure the effective dynamic system of entrapment , favorable direction of migration and conduit system and dissects the present reservoir and structural style , finally points out the likely models of entrapment . the main achievements can be summarized as followings : 1 本文从成藏动力学系统划分入手，重点追溯成藏作用和过程研究，确定有效成藏动力学系统，确定有利运移分配方向和单元，指出有利的输导体系，并在以上基础上解剖有利区的构造样式和现有油藏特征，提出适合本区特征的成藏模式。
