Abstract: A method, a device and a medium for acquiring logging parameters are provided, wherein the logging parameters include gas-bearing porosities, and the method includes: acquiring a two-dimensional nuclear magnetic logging analysis graph; determining a gas-bearing region from the two-dimensional nuclear magnetic logging analysis graph; and summing contour values of the gas-bearing region as a gas-bearing porosity. The device for acquiring logging parameters includes a processor and a computer readable storage medium, wherein instructions are stored in the computer readable storage medium, and the processor executes the instructions to perform the foregoing method for acquiring logging parameters. The medium for acquiring logging parameters stores computer executable instructions, which are used for executing the foregoing method for acquiring logging parameters.

Abstract: A vibration detection apparatus applied to a nuclear magnetic resonance while drilling instrument, including a vibration table. The vibration table is configured to horizontally clamp the nuclear magnetic resonance while drilling instrument and further includes a graduated barrel that contains a detection liquid; the graduated barrel is configured to be suspended at the upper side of the vibration table and be spaced apart from the nuclear magnetic resonance while drilling instrument; when the vibration table performs vibration, the graduated barrel keeps stationary, and the nuclear magnetic resonance while drilling instrument preforms high-pressure emission and measurement by means of the graduated barrel. Therefore, the nuclear magnetic resonance while drilling instrument can obtain the echo signal of the graduated barrel during vibration, thereby more accurately detecting the performance thereof and shortening a detection time length.
