在 2 0 0 2年SPWLA年会上 ,日本科学家提出了一种新的测井系统 ,称之为电动测井 (EKL)。这种方法源于如下现象 :毕奥特快纵波在穿过渗透率、孔隙度等参数变化的界面时会产生毕奥特慢纵波 ,后者很快衰减并产生电信号。在两口井中的测试表明 ,该系统对于估算土壤和岩石的渗透率具 At the SPWLA annual conference in 2002, Japanese scientists proposed a new logging system called Electric Logging (EKL). This approach stems from the phenomenon that a Biotz-fast longitudinal wave produces a slow Biot-wave on an interface that varies through parameters such as permeability and porosity, which decay rapidly and produce electrical signals. Tests in both wells show that the system is useful for estimating soil and rock permeability
