Abstract

Magnetroresistive sensor has advantages that it can be easily installed

small volume and non-contact with measured objects directly. A new type of six-arm caliper logging tool based on magnetroresistive sensors which can measure diameters of open hole is introduced

and effect factor of measurement error has been analyzed.Through experimental test

results show that measurement precision of six-arm caliper logging tool can reach2. 5 mm

it has some obvious advantages on resolution and reliability and maintenance

compared with traditional logging tool

thus it has a broad prospect of popularization and application.
