Geophysical Metallic borehole Logging Equipment Mineral Borehole 3 Axis Magnetic Logger Equipment

Product Overview

Description

Geophysical Metallic borehole Logging Equipment Mineral Borehole 3 Axis Magnetic Logger Equipment

 

 

 

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
