PROCEDURE TESTING EQUIPMENT OF ELECTROMAGNETIC LOGGING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: industrial geophysics. SUBSTANCE: conductive ring is placed on axis of probe in position corresponding to zero value of measured phase difference between e m f induced in measurement coils of probe, then ring is moved through certain distances, value of specified phase difference is measured after each move, measured values are compared with rated values and comparison results are used to evaluate characteristic of tested equipment. Device for implementation of procedure has conductive ring and capacitor. Ring is made of high-resistance wire. Connector used to connect ring to testing plant to measure complex resistance of ring is placed in series in electric circuit of ring. Ring is fitted with mechanism securing precise setting of ring in required position. EFFECT: raised accuracy of test of equipment of electromagnetic logging. 2 cl, 3 dwg
