Drilling, MWD (Measurement While Drilling)

Via real time drilling parameters recording, it is possible to analyze the geomechanical characteristics of soil. Depth based diagraph underlines different stratigraphic soil levels.
DAT instruments offers two types of dataloggers for drilling:
JET SDP / IB, simple and cheap
JET 4000 AME / J, expandable with Jet Grouting function

 

JET SDP / IB, datalogger for drilling

JET SDP / IB
Display, directly on datalogger LCD, of instantaneous recorded parameters, of graphics in terms of depth and of summarizing data. Data downloading to PC in order to process, file, export and print exhaustive reports. Measuring and recording of the following selectable parameters:

  • drill depth (JET DEPTH)
  • feed force (JET FORCE)
  • translation rod speed (JET DEPTH)
  • boring rod rotation torque (JET TORQ)
  • boring rod rotation speed (JET ROT)
  • water pressure (JET PRESS)
  • date and time of drilling and duration
  • soil relative energy
