2-3/4” DUAL RECEIVER RADII™
CEMENT BOND W/TEMP. SENSOR
PART NUMBER 050-RADII-275T
© 2007 Probe Technology Services, Inc. All rights reserved
The Radii™ Cement Bond Tool, utilizes a single ceramic transmitter, an eight segment receiver
at 3 foot spacing and a single receiver at 5’ spacing to accurately measure the quality of
the cement job in a cased hole well environment. The segmented receiver provides good indication
of cement channeling behind the casing. The optional temperature sensor is mounted
close to a transmitter enabling a temperature log while running into the well to provide additional
cement quality information.
The tool is all stainless steel construction with oil filled, pressure compensated transmitter and
receiver sections. The transmitter and both receivers are ceramic to withstand the hostile high
temperature well environments. On each transmitter firing data from all the receivers is digitized,
stored in internal memory and then sequentially transmitted to the surface computer.
The digital signal section is capable of transmitting to the surface data from Gamma Ray/CCL
above the Radii CBL an in-line neutron, a compensated neutron or other tool that has one or
two pulse channels run on the bottom of the CBL tool.
Transmission of the sonic data to the surface is accomplished by an internal controller which
transmits 8 signals from the RADII receiver, a composite 3’ signal which is the sum of all 8
RADII signals, a 5 foot receiver signal, and an internally generated calibration signal. Transmission
of the remaining signals are digitally encoded data transmitted between the acoustic
signals.
The electronics contains firmware that allows the tool to be auto-calibrated in a calibration fixture.
The digital gain is set and all signals are stored in memory. These signals can be transmitted
uphole on demand by the operator.
