Applications and Feature

1 Used for magnetic exploration in wells. Suitable for use in drilling with diameter greater than φ46mm for measurement of horizontal component X, Y and vertical component Z in magnetic field. Can also be used as high-precision inclinometer with non-magnetic hole or far away from magnetic well. It can solve the following issues.

2 Verify ground magnetic abnormality, and determine the nature of abnormality.

3 Combined with ground magnetic survey for three-dimensional interpretation.

4 High-precision measurement of deviation azimuth and inclination.

5 Instruct the drilling arrangement, and guide the drilling.

6 Determine the depth and direction of blind ore.

7 Determination of ore body position, extension, range and thickness of exposed ores.

8 Determination of the occurrence of ore bodies.

9 Searching of magnetic ore associated ore deposits.
