Gel-based solid physical simulator for electrical logging detector and forming method of gel-based solid physical simulator

Abstract

The embodiment of the invention provides a gel-based solid physical simulator for an electrical logging detector and a forming method of the gel-based solid physical simulator. The gel-based solid physical simulator comprises a lower surrounding rock bed, a target stratum and an upper surrounding rock bed which are arranged sequentially from bottom to top and a wellhole which penetrates through the lower surrounding rock bed, the target stratum and the upper surrounding rock bed vertically, wherein the target stratum comprises a target stratum undisturbed formation and a target stratum invaded zone which are arranged sequentially from outside to inside; and the wellhole penetrates through the target stratum invaded zone vertically. According to the solid physical simulator, hydrophilic macromolecular elastic gel is used as a critical material for simulating formation modules; and the solid physical simulator can be used for performing physical simulation on the full-size electrical logging detector, and can also be used for detecting the logging response characteristics including longitudinal and radial detection characteristics, measuring accuracy and longitudinal resolution of the detector.
