Application Areas

 Model SJAT50 Cement Bond Combination Logging Tool is an instrument mainly used for the test of cement bond quality of small diameter casing pipe. The tool consists of casing collar locator (CCL) / telemetry cylinder / natural gamma tool and sonic cement bond tool.

Model SJAT50 Cement Bond Combination Tool

Features

The tool is characterized by small diameter (only 50mm), light in weight, reliable working performance, accurate metering, high successful rate and others. It is one of the optimum choices for cement bond quality test. It can collect multiple well testing curves as CCL, natural gamma, 2.5’ X1R1 sound amplitude, 2.5’ X1R1 transmission time, bond index, damp, variable density and etc.
