The present invention improves measurement of the formation induction response in the presence of the primary magnetic field generated by a logging tool's transmitter. In a exemplary embodiment of the present invention, a structure is provided having a new combination of electrical and mechanical design features which provide logging tool for internal calibration and checking of antenna performance and characteristics before during and after well logging operations. In one aspect of the invention a logging tool is provided comprising a verification winding for coupling a verification signal into the receiver coil.
L'invention concerne l'amélioration des mesures de réponse d'induction d'une formation en présence de champ magnétique primaire produit par un émetteur d'instrument de carottage thermique. A titre de variante, on décrit une structure à combinaison de caractéristiques électriques et mécaniques qui permettent pour un tel instrument l'étalonnage interne et la vérification de performance et de caractéristiques d'antenne avant, pendant et après les opérations de carottage thermique. Selon un aspect, on décrit un instrument de carottage thermique qui comprend un enroulement de vérification pour le couplage de signal de vérification dans une bobine de récepteur.
