2 3/4" RADII™ Dual Receiver Cement Bond Log Tool + Temperature

Product Reference: 050-RADII-275T

The RADII™ Cement Bond Tool, utilizes a single ceramic transmitter, 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 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.

This cement bond tool is 100% 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 of well environments. Upon each transmitter firing, data from all 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 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 3ft. signal (sum of all 8 RADII™ signals), a 5ft. receiver signal, and an internally generated calibration signal. Transmission of the remaining signals consist of digitally encoded data transmitted between the acoustic signals.

The electronics contains firmware that allows the tool to be auto-calibrated inside 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.
