During building 2D model, I use the concepts of point, segment, line and plane, the segment can be formed from points, then line can be formed from segments, the closed curved plane can be obtained by around lines, and finally the 2D model can be built by closed curved plane; I express the un-smooth stratum or fault by linear fitting and express the smooth stratum or default by cubic spline fitting segmentally, in this way I can describe the variation feature of 2D interface properly.

Highprecision sequence stratigraphy was applied to divide and correlate the different sequence stratigraphical units from the Upper Cretaceous to plaeogene in the Biyang depression, and a sequence stratigraphic framework which can correlate the different sequence stratigraphical units was set up to point out that the ramp region of the northdepression is an oil and gas reservoir featured by altitude progradational delta and complex fault blocks, the inner belt of the north slope hinge zone is a low order faultlithologic oil and gas reservoir, the development stages and high order terms of the deep depressed area is a fluxoturbidite and sublacustrine fan lens trap, and the south actic region is a lithologic hydrocarbon reservoir development area.

运用高精度层序地层学的理论，系统地划分和对比泌阳凹陷上白垩统至古近系不同级别的层序地层单元，建立了凹陷内各级层序地层单元的对比框架，指出凹陷北部斜坡带为高位进积三角洲复杂断块群油气藏，北部斜坡枢纽带内带为低位扇断层-岩性油气藏、深凹区湖扩展期和高位期为滑塌浊积体及湖底扇透镜体圈闭，南部陡坡带为岩性油气藏发育区。

The Upper Submember of the 4th Member of the Shahejie Formation in Huimin Depression represents one third-order sequence according to sequence stratigraphic analysis based on well log and seismic reflective data. Lowstand, lacustrine transgressive and highstand systems tracts can be recognized based on the stacking patterns and changes of lithology and lithofacies. The sequence stratigraphic correlation of well-tie sections made it possible to construct the regional stratigraphic framework.
