Application Areas

    Model SMC38 Manchester Five-parameter Combination Tool is applicable to the test of injection profile with the help of isotope tracer in water injection wells, depth correction, leakage detection and other engineering tests. On the basis of Model SMC38 Manchester Four-Parameter Combination Logging Tool, the new type has three more parameters in it, namely, flowmeter, upper and lower centralizer, and explosive isotope releaser.

    1. The tool runs on a single-conductor cable and utilizes Manchester Ⅱcode for signal coding;
    2. Five parameters can be tested with just one run, which simplifies operation and improves logging efficiency;
    3. In the water-injection wells, as an assistant tool, flow meter can timely find the effect of “arge pole path” in the strata on the isotope logging system so as to reduce logging error and improve accuracy.
