古地貌恢复研究目前大都停留在定性阶段,沉积记录资料越多则恢复精度越高,故一些定量化手段有待进一步研究。本次研究综合利用钻孔、地震、测井等资料,在残余地层厚度平面图的基础上,经去压实校正,得出八道湾组的原始沉积厚度,并由此恢复出八道湾组沉积期的古地貌。研究结果表明,古地貌对八道湾组沉积体系分布具有明显的控制作用。
Paleogeomorphic restoration research mostly stays in the qualitative stage at present, the more sedimentary records data, the higher the recovery accuracy, so some quantitative methods need further study. In this study, the original sedimentary thickness of the Badaowan Formation was obtained by using the data of borehole, earthquake and well logging. Based on the plan of the thickness of remaining strata, the original sedimentary thickness of the Badaowan Formation was obtained, and the sedimentary period of the Badaowan Formation was recovered Ancient landforms. The results show that paleogeomorphology has a significant control over the sedimentary system distribution of the Badaowan Formation.
