Electromagnetic resistivity logging while drilling is the use of electromagnetic wave propagation in the medium, the absorption of electromagnetic waves in different media, different, different sources by measuring the distance between the electromagnetic wave receiving coil the amplitude ratio or p

Drilling electromagnetic wave resistivity logging is to use electromagnetic waves in different media, media in the dissemination of electromagnetic waves by measuring the absorption differences from different sources in the electromagnetic spectrum between receiving coil is lower than or 相位差 resisti

Along with drills the electromagnetic wave electrical resistivity logging is uses the electromagnetic wave disseminates when the medium, the different medium to the electromagnetic wave absorption difference, through the survey different source-detector separation receive coil between the electromag

Electromagnetic wave-while-drilling resistivity logging is the use of electromagnetic waves in media propagation, electromagnetic wave absorption of different media, different spacing between receiving coils of electromagnetic waves by measuring the amplitude or phase difference, to complete the for

It is while utilizing the electromagnetic wave to travel to get into the electromagnetic wave resistivity and log well at the same time in the medium, the absorption difference to the electromagnetic wave of different mediums, it is worse than or the phase place to receive the range of the electroma
