小波分析在测井数据融合处理中的应用

通过分析测井信号曲线能够较好地解决实际的工程问题,综合利用多条测井信号所反映的地层信息,应用小波分析方法将多条测井曲线信号融合成一条参数曲线。对融合后的参数曲线解译,增强了原始测井曲线中所包含的共有信息,削弱了单条测井信号中存在的偶然误差,使得测井数据的可信度大大提高。

Application of Wavelet Analysis to Multi-scale Fusion Processing of Well Logging Data

Using signal well logging curve can solve practical engineering problems. By the utilization of layer information reflected by multiple logging curves, multiple logging curves are fused into a new parameter curve by wavelet multi--scale analysis. Based on the theory of signal detection and multi--scale analysis, public information of the original curve has been strengthened, the accidental error of single well data has been reduced and the credi- bility of comprehensive well logging data has been improved.
