METHOD AND APPARATUS FOR INDUCTION WELL LOGGING DURING DRILLING PROCESS |
| 摘要 |
FIELD: physics. ^ SUBSTANCE: method involves passing current pulses through an exciter coil and recording emf of transient processes in a measuring coil. The effect of emf of the drill column on the measured signal is eliminated by a transient process signal measured at time t>30 mcs. ^ EFFECT: high accuracy of measurements by taking into account the effect of the drill column on the results. ^ 8 dwg |
