25mm Geological Borehole Surveying Instrument

  Product Description 25mm Geological Borehole Surveying Instrument 1. Product Introduction  This product can use rope coring drill tool to complete the measurement of wellbore trajectory at well bottom point.   2. Application Scope   For the measurement of well trajectory during drilling process in the industry of petroleum, geology, coal, water conservancy etc.     3. Product Picture
      4. Product Features:                                                                                   1) Allow various measuring methods, wide adaptability:Equipped with different reducer union, the same probe-tube is available for different size of rope coring drill tools. 2) Available for deep well measurements: The maximum pressure bearing capacity is 100MPa, and it allows measurement at a depth of more than 4000m. 3)  Low power consumption design, long working hours:With the low power consumption design, a fully charged battery can guarantee a continuous working for more than 80 hours. 4) Intelligent indication function:Whether the working state of the probe- tube is normal or not can be seen from the indicator light on the probe-tube panel. 5) Particular Power-off protection:It will not affect the instrument’s normal work even if there is a sudden outage caused by special strong vibration or impact. 6) Good resistance to impact and vibration:The instrument is radially and axially equipped with multistage buffering devices, which effectively improves the impact resistance as well as the vibration resistance of the instrument.    5.
