The RadII Cement Bond Tool utilizes a single ceramic tran-smitter, an eight
segment receiver at 3 ft. spacing, and a single receiver at 5 ft. spacing to
accurately measure the quality of the cement job in a cased hole well envir-
onment. The segmented receiver provides good indication of cement
channeling behind the casing.
The small diameter tool contains oil filled, pressure compensated transmitter and receiver sections. The transmitter
and both receivers are ceramic to withstand the hostile high temperature of well environments. On each transmitter
firing, data from all the receivers is digitized and stored in internal memory, then sequentially transmitted to the surface
computer.
The digital signal section is capable of transmitting to the surface data from a Gamma/Ray CCL and an In-Line Neutron,
a Compensated Neutron or other tool that has three or less pulse channels run on the bottom of the CBL tool. The tool
also accepts PTX digital telemetry from below.
Transmission of the sonic data to the surface is accomplished by an internal controller, which transmits eight signals
from the RADII receiver, a composite 3-foot signal (the sum of all 8 RADII signals), a 5-foot receiver signal, and an
internally generated calibration signal. Transmissions of the remaining signals are digitally encoded data transmitted
after 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 up hole on demand by the operator.
