相关系数在松北地区表层建模中的应用分析
|
摘要
为了提高松北地区表层模型的建模精度,通过对相关系数内插原理的分析,基于高密微测井资料,系统研究了影响相关系数取值的各种因素,结合对松北地区表层沉积规律的认识,总结出松北地区相关系数取值的方法,提高了表层建模精度,改善了单炮激发效果。相关系数的合理应用,提高了松北地区表层建模的精度,其计算准确性受地表起伏的影响较大,应清楚地认识该区的表层沉积特征,根据地形起伏程度采取不同的计算方法,人机交互才能保证表层建模的精确性。
In order to improve the modeling accuracy of surface models in the Songbei region, various factors affecting the correlation coefficient values were systematically studied using an analysis of the interpolation principles of correlation coefficients and based on high density micro-logging data. Combined with the knowledge of the surface deposition patterns in the Songbei area, the method for determining the correlation coefficient values of the Songbei area was summarized. This improves the accuracy of surface modeling and the effects of single-shot excitation. Reasonable application of correlation coefficients improves the accuracy of surface modeling in the Songbei area. The accuracy of the calculation is greatly affected by surface fluctuations. It is necessary to clearly understand the surface sedimentary characteristics of the area, adopt different calculation methods according to the degree of topographic relief, and leverage human-computer interaction in order to ensure the accuracy of surface modeling.
