MCT-Multi-finger Caliper Tool

The Multi-finger Caliper Tool (60-finger) is a mechanical tool for well diameter measurement. It is mainly composed of measuring fingers, driver rod and inductive sensors. Each finger is independently connected with a sensor, which transforms radial change of casing inner wall damage to longitudinal change during moving and the well diameter is thus measured.

The tool is combinable with electromagnetic inspection tools and Gyro tool for comprehensive evaluation and interpretation to realize 3D presentation.

The Multi-finger Caliper Tool (24-finger) is a mechanical tool for hole diameter measurement. Each finger is independently connected with a sensor, which transforms radial measurement of the casing inner wall to detect longitudinal change during movement.

The Multi-finger Caliper Tool (40-finger) is a mechanical tool for well diameter measurement. The sensing section consists of 40 displacement sensors, which are uniformly distributed on the outer circumference, with each sensor able to measure the slightest variation in diameter. The tool also includes an inclination sensor and a rotation sensor.
