摘要
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。
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.
