1 11/16" RADII™ Dual Receiver Cement Bond

Product Reference: 050-RADII-170

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 ft. signal (the sum of all 8 RADII™ signals), a 5 ft. 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 uphole on demand by the operator.
