The accommodation analysis revealed that the distribution of strandline sands for this area is controlled by the distribution of stratigraphic base level and the paleogeographic features.

可容空间分析说明，本区分流河道砂体的分布规律是受地层基准面分布状况和古地形控制的。

Sedimentologic and stratigraphic attributes of rocks are the function of the ratio of accommodation and sediment supply.

因此，由基准面旋回所控制的等时地层单元的地层分布是有规律可循的，因而也是可以预测的。

A new method of post-stack seismic forward modeling under complex surface conditions was proposed from the point of seismic modeling It used the theory of submerse topography and zero-velocity layer, the new method firstly transformed the original surfaceto a level , and got a new model.

基于波动方程基准面延拓的偏移方法理论，从地震波场正演模拟的角度出发，提出了一种新的适用于起伏地形的地震叠后正演方法。

The faulted scarp type slope break belt controlled the development of the near shore sub-aqueous fan system. The faulted terrace type steep slope break belt controlled the development of the fan-deltas and sub-aqueous fan system. The gentle slope type slope break belt controlled the development of the fan delta system. The inner basin type slope break belt controlled the off shore sub-lacustrine fan system in the basin-level falling stage.

断崖型陡坡坡折带控制着近岸水下扇沉积体系的形成和分布；断阶型陡坡坡折带控制着扇三角洲或近岸水下扇及前方的湖底扇体系的形成和分布；断阶型缓坡坡折带控制着扇三角洲沉积体系的形成和分布；在基准面下降阶段，盆内坡折控制着远岸湖底扇的形成和分布。

This fixture should be provided with a reference leveling surface, so that it can be kept level as the balance deflects

这种装置应该有一个水平基准面，以便在天平变形时能够使之保持水平。

Applying the principles and methods of high-resolution sequence stratigraphy, and combining with the data of exploration wells and development wells in encrypted network of wells, the authors identified 41 short-term base-level cycles of 7 types, which were formed under the conditions of deeping upward, shallowing upward, symmetrical in different accommodation space in Fuyu oil layer of Chao 1-Chao gas 3 blocks, and makes detailed analysis on the genesis and characteristics based on the sedimentary dynamics.

运用高分辨率层序地层学原理和方法，结合探井及密井网开发井资料，在朝阳沟油田朝1-朝气3区块扶余油层识别出向上&变深&、向上&变浅&、对称型及其不同可容纳空间条件下的7类共41个短期基准面旋回，并以沉积动力学观点详细剖析了其成因及特征。

The formation of system tracts, their combination characteristics and application in hydrocarbon exploration, as well as the case studies of the Bohai Bay Basin, were studied in this paper.

结合渤海湾盆地的勘探实例，分析体系域的成因机制、组合特征和勘探规律，认为：体系域是基准面变化等因素作用的产物，不同级别的层序都发育着与其对应的体系域；一般情况下，三级层序对应的体系域单元与含油气层的规模相匹配，但四级层序对应的体系域才是隐蔽油气藏赋存的有利部位。
