【摘要】 主要针对沙丘曲线静校正应用效果进行分析。通过对沙丘曲线法、模型法和大炮初至法资料处理效果的对比分析,说明沙丘曲线法静校正是解决高大沙丘地区地震资料静校正问题的一种比较好的方法,而采用分厚综合沙丘曲线静校正则效果更佳。通过对沙漠典型地区的资料分析说明,沙漠腹地物性成因简单,应用一条沙丘曲线就可以得到较好的效果;而沙漠边缘因物性成因比较复杂,需建立详细的沙丘曲线数据库,根据测线的具体情况进行应用,才会得到较好的效果。更多还原

【Abstract】 The applications of dune curve were discussed.Compari- sons between data from dune curve,modeling and first breaks of refractions indicate that the dune curve is a relatively effec- tive method in solving static problem in dune-covered areas. Statics with dune curve of adaptive thickness yields better re- sults.Analysis of real data showed that satisfactory results can be achieved by using one single dune curve in the hinterland of desert due to the simplicity of petrophysics,whereas dune curve database should be established and adopted to account for the variations of the dune curve in the border area of the des- ert.更多还原
