Applications and Feature

• 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.
• Verify ground magnetic abnormality, and determine the nature of abnormality.
• Combined with ground magnetic survey for three-dimensional interpretation.
• High-precision measurement of deviation azimuth and inclination.
• Instruct the drilling arrangement, and guide the drilling.
• Determine the depth and direction of blind ore.
• Determination of ore body position, extension, range and thickness of exposed ores.
• Determination of the occurrence of ore bodies.
• Searching of magnetic ore associated ore deposits.
