摘要
声电效应测井仪 (EKL)利用岩石声电效应来求取渗透率和地层水电阻率 ,与声波测井仪器不同的是 ,该仪器利用声源在井中发射声波 ,测量声波在地层中激发的转换电场信号。文章介绍了该仪器的测量原理、微弱信号检测技术。
Permeability and water resistivity are gained based on the seismoelestic effect of the rock. Differing from the acoustic logging tool, EKL measures the converted electric signals in the formation when the acoustic wave propagates in the borehole. The principle and the weak signal detection technology of EKL are introduced, and the revelation obtained from EKL is also discussed in this paper.
