Product Description Product Description Geological Borehole DIP Logging Instrument Downhole Inclination Logging System Magnetic Hole Inclinometer Drilling Borehole Deviation Survey Tool The Geological Borehole DIP Logging Instrument, also known as the Downhole Inclination Logging System or Magnetic Borehole Inclinometer, is a crucial tool for measuring borehole inclination, deviation, and trajectory. Its applications in geological surveys, wellbore stability assessment, drilling optimization, and borehole deviation surveys contribute to accurate well placement, improved drilling efficiency, and enhanced geological understanding. The use of a borehole inclinometer aids in real-time monitoring and decision-making during drilling operations, ensuring successful and safe drilling campaigns.Main Applications and FeaturesDigital inclinometer is a new high-precision inclinometer system which consists of ground instrument, probe, cable and other components. It is widely used in measurement of vertex and azimuth for various types of geological drilling.Widely used in measurement of vertex and azimuth for various types of geological drilling.Direct-reading of vertex and azimuthDigital display, point measurement or continuous measurementSimple, reliable operation,Vertex Coverage0~60°Vertex Accuracy≤ 0.1°Azimuth Coverage0~360°Azimuth Accuracy±4° (Vertex ≥ 3°), ±6° (2° ≤ Vertex ≤ 3°)Working Temperature0~85 Probe Outline Dimensionφ42×1000 mmGround Instrument Dimension240×95×140mmProbe Weight2 Kg (weighing bar 5 Kg)Probe Downhole Length≤500The general principles for selecting an inclinometer are:(1) First of all, to confirm whether it is a magnetic mining area, whether it is subject to magnetic interference, in order to confirm whether the magnetic inclinometer or the gyro inclinometer is used.(2) Select the appropriate inclinometer measurement range and accuracy index according to engineering technical requirements. It is impossible to blindly pursue high precision, and the instrument has high precision, and its cost and price are also high.(3) For single point inclinometer and multi-point inclinometer, according to the drilling depth of the project, the single point inclinometer is used when the hole depth is below 100-200m, and the multi-point test should be used for the hole above 200m. Inclinometer to improve the efficiency of the slope measurement.(4) For the inclinometer used in coal mines, a borehole inclinometer with an explosion-proof safety device should be used.There are several ways to measure the deviation of boreholes, and what method that is best for you depends on what sort of borehole you have.But for all boreholes we want to place the survey tool at a given depth, called a survey station. At that survey station we want to make a measurement, sometimes called a survey shot, to get the azimuth and inclination. The azimuth and inclination, together with the depth are used to calculate the borehole trajectory.Inclination: 0°stands for vertical;Azimuth: GDY-2GW finds the True North which is the direction along a meridian towards the geographic North Pole.The True North is different from the Magnetic North and there is an angle between the two orientations called magnetic declination.Magnetic declination or variation is the angle on the horizontal plane between magnetic north (the direction the north end of a compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north. This angle varies depending on position on the Earth's surface, and changes over time.By convention, declination is positive when magnetic north is east of true north, and negative when it is to the west.
