It is important and difficult for isochronous correlation datum of fluvial facies stratum in exploration and development of petroleum, while high resolving power of sequence stratigraphy based on the datum plane cycle is an additional feasible technical method for it.

河流相地层的等时对比一直是油气勘探开发的重点和难点，而基于基准面旋回的高分辨率层序地层学则为此增添了行之有效的技术手段。

Snap lines can be assigned to a view, a datum plane or any geometry edge and then move with that view.

捕捉线能够被指定给一个视图，基准面和任何边线，并且，捕捉线会跟随视图移动。

At present, the main approach for seismic data imaging is the prestack Kirchhoff time migration, however, violent variation of surface elevation makes the datum plane selection of prestack time migration very difficult.

目前该类地区地震勘探中主要的成像手段依然是Kirchhoff叠前时间偏移。但地表高程的剧烈变化使叠前时间偏移的基准面很难选择。

Datum plane and side planer or milling machine in the processing; face away from the machine only needs a general cross-section.

平面和侧面的基准面可在平刨床或铣床上加工；端面一般只需要距机横截。

So far the pattern of seismic prestack depth migration is the same as it abroad. Before the work of velocity building the original seismic data must be corrected on a datum plane, and then to make the prestack depth migration work.

目前我国叠前深度偏移的研究方向与国外基本一致，特别是在目前油田的实际勘探中，大多套用国外的模式，一般都是对原始资料校正在一个基准面后，然后开展叠前深度偏移工作。

Palaeogeomorphology is a main factor to control the development and distributing of the sedimentary facies like the geomorphology today which is affected by the factors such as the location of the area tectonics, weather, the change of the datum plane and the tectonics movements.

古地形地貌是控制一个盆地后期沉积相发育与分布的一个主要因素，同现在地貌一样，古地貌形态受到了所处的区域构造位置、气候、基准面变化及构造运动等因素综合作用的影响。
