合成偏移(SYNDEV)图是处理井斜倾角资料所作出的图件。从这些图件中能够识别出那些在标准倾角矢量图或累积倾角图上不很明显的隐含地质特征。假想的井孔就如同发生井斜耶样展示在图上。一组SYNDEV图包括水平位移图、平面图、剖面图、总方位角和方位角差图。把上述这些不相关的图件组合成较大的相关分析图件后,水平位移图可以代替累积倾角图,而位移平面图可取代倾角一方位角一矢量图,另外两个与SYNDEV相关的有用图件是倾角差和全角差图。 The composite offset (SYNDEV) plot is a map of the well inclination data. From these maps, it is possible to identify those implicit geological features that are not obvious on a standard dip or cumulative dip. The hypothetical borehole is just like the one that was shown. A set of SYNDEV maps includes a horizontal displacement map, a plan view, a section view, a total azimuth and azimuth difference map. After these uncorrelated figures are combined into a larger correlation analysis graph, the horizontal displacement map can replace the cumulative inclination map, and the displacement plan can replace the azimuth-elevation vector diagram. The other two useful maps related to SYNDEV Pieces are the angle difference and the full angle difference chart.
