LORD PRODUCT DATASHEET Downhole Orientation Sensor and Data Logger The 3DM-DH3™ is a downhole orientation sensor and datalogger. It incorporates acceleration sensors, magnetic field sensors, and temperature sensors, together with an on-board microprocessor, embedded software algorithm, non-volatile memory for configuration, flash datalogging memory, and serial communication interface. Its form-factor, rated temperature range and power supply requirements are optimized for downhole applications. The 3DM-DH3™ provides accurate drill path measurements including Inclination, Azimuth, GTF, MTF, Dip Angle, sensor temperatures, G-TOT and H-TOT. Features & Benefits System Overview The 3DM-DH3™ can be deployed out of the box for immediate use in downhole operations, integrated into an existing system to provide an electronic measurement component, or incorporated into an OEM product. precise downhole orientation high-speed sample rate & flexible data outputs extended use, low-power data logging Easiest to Use rapid deployment in the drill string outputs drill path measurements Cost Effective reduced cost and rapid time to market for customer’s applications aggressive volume discount schedule Applications Downhole Orientation Vertical Wells Physically, the 3DM-DH3™ is easily mounted into the drill string using its body’s threading attachments. It can be tethered to an RS-422 communication cable for continuous real-time measurements to a host computer during drilling operations, or it can be remotely deployed and run as a datalogger, with data retrieval after it has been run through the drill path. The unit can be powered through the communication cable tether from a platform source or by batteries. The unit is factory calibrated and ready for use with power-up. The unit ships with easy-to-use PC software which allows the user to configure and operate the instrument, view real-time measurements or download logged data for post-processing.For those users, integrators or OEMs who develop their own applications, the 3DM-DH3™ is shipped with a complete Data Communications Protocol manual which provides the developer with a complete instrument command set. Applications of your own design can readily be developed in any coding language and on any computing platform including microprocessors.
