Description
Technical field [0001] The present invention relates to the field of logging testing, and in particular, there is a non-movable structure and a logging instrument having it. Background technique [0002] Logging instruments using logging cables can generally be divided into two parts: guiding fiber optic cable and instrument cable. Among them, the leading cable length is long, from a few kilometers to dozens of kilometers, the main role is that the instrument unit extends into the downhole by ground equipment (such as log cars, etc.), the instrument cable is shorter, the length is generally Millions to several kilometers are not suitable for connecting instrument cells (such as VSP detector units, etc.). In installation, transportation, and on-site construction, considering security, stability, and reliability, the guided fiber optic cable and instrument cable are typically separated, and when the logging instrument is used in the well, it will guide the cable and The instrument ...
