基于层位解释的断层多边形自动组合技术
|
摘要
基于沿层相干体水平切片的断层多边形自动组合技术已日臻成熟,且断层多边形自动组合的精度取决于相干体处理的质量。由于相干体的异常信息并非都是断层的反映,因此在沿层相干体水平切片上提取组合的断层多边形难以用来精确地编制构造图。基于此,本文提出利用层位解释的时间属性数据进行断层的提取,并自动形成断层多边形文件,进而精确编制构造图。这种方法不但可避免手工断层多边形组合存在的拾取误差,而且大大提高了解释效率。在三维地震4×4CDP解释网格上便可进行准确的断层多边形自动组合,其准确率可达98%。
The automatic composition of fault polygon based on horizontal slice of horizontal coherent volume has been become mature day by day, and his precision depends on the quality of coherent volume processing. Since abnormal information of coherent volume does not totally reflect the fault, it is difficult to use composed fault polygon picked up from the horizontal slice of horizontal coherent volume for preciously drawing the structural map. For that reason, the paper presented using time attribute data of horizon interpretation to pick up the fault and automatically form fault polygon file, and further to draw structural map preciously. The method is able to not only avoids pickup error existed in hand fault polygon composition, but also greatly improves the interpretation efficiency. The accurate automatic composition of fault polygon can be implemented in 3D seismic 4*4 CDP interpretation grid, and accuracy can reach to 98%.
