Microresistivity

انقر فوق الموارد The microresistivity probe provides a focussed pad resistivity measurement with high vertical resolution combined with a caliper and natural gamma.

Principle of Measurement:

http://sejrup-it.dk/?centosar=%D9%83%D9%85-%D8%B3%D8%B9%D8%B1-%D8%A7%D9%84%D8%B0%D9%87%D8%A8-%D8%A7%D9%84%D9%8A%D9%88%D9%85-%D8%A7%D9%84%D8%B3%D8%B9%D9%88%D8%AF%D9%8A%D9%87&956=57 The resistivity measurement is based on the guard principle where a ring electrode maintained at the same potential as the central measurement electrode focusses the measure current into a narrow beam. The electrodes are contained within a flexible pad mounted on a motor-driven arm and maintained in contact with the borehole wall during logging. The same arm also operates the caliper mechanism. A natural-gamma measurement is included to aid correlation with other logs.
