Detailed Product Description

I.Application Areas
  Model SMC38 Manchester Four-Parameter (three-parameter) Combination Logging Tool is mainly applicable to the test of injection profile with the help of isotope tracer in water injection wells, and also for depth correction, leakage detecting and other engineering tests. The tool integrates CCL, temperature, gamma, pressure and remote testing board, which can be used to monitor pressure changes in the well so that proper measures can be taken in time during abnormal pressure conditions.

II.Features
  1.The tool runs on a mono-conductor cable and utilizes Manchester code for signal coding;
  2.Four parameters are tested simultaneously, which greatly  simplifies operation and improves logging efficiency;
  3.If necessary, pressure parameter can be taken off from the tool string to have a three-parameter combination logging tool;
  4.Its rational structure, simple pressure calibration procedure, short length and reliability make it the first choice for water injection profile test.
