摘要
本文对井中声波透视观测资料在直线型射线重构模型的基础上,利用代数重建法(ART)和联合迭代重建法(SIRT),对井中实验数据和实测资料进行了多参数反演,给出了声速度和声吸收系数的层析图.为了综合解释多参数成像结果和地质资料,采用了模糊模式识别法提出了新的成图参数——矿优度,给出三种图形显示方式.其结果表明:CT 技术和模糊模式识别法运用于声资料的处理,增强了解决地质问题的能力.
Based on the straight-line optics model,the experimental and field data collected in well were inversed bythe algebraic reconstruction techniques (ART) and the simultancous iterative reconstruction techniques (STRT).The tomography of acoustic velocity and absorptivity are illustrated.In order to obtain a comprehensiveinterpretation of the tomographic results of multi-parameter and the gecological information,a new mappingparameter (ore certainty) and three types of representations of comprehensive images are developed using afuzzy pattern recognition method (FPRM).The results indicate that CT and FPRM can be successfully appliedto the acoustic data processing,and the ability of solving geological problems is thus improved.
