Disclosed are a hybrid density abrupt interface inversion method based on machine learning constraints. The inversion method includes constructing an initial basin interface and randomly generating a disturbed basin interface data set; obtaining a basin interface data set through Hadamard product operation on the initial basin interface and the disturbed basin interface data set; obtaining a high-resolution density interface model data set through filling the basin interface data set with advanced functions; performing forward calculation to obtain a simulated gravity data set; carrying out mathematical transformation on the simulated gravity data set and weighting to obtain a low-resolution migration density interface model data set; optimizing a migration model-based deep learning network and mapping to obtain a high-resolution constrained density interface prior model; and constructing a stable nonlinear loss function and performing regularization inversion to obtain a high-resolution density interface model.

Disclosed are a simulation platform and a simulation method for leakage detection and treatment. The simulation platform includes a water tank open at the top, which is a holding device; simulation sand, which is laid at the bottom of the water tank, and the upper area of the simulation sand is the experimental water filling area for filling simulation water; a leakage simulation device, which is buried in the simulation sand; a plurality of electrodes, which are distributed on the simulation sand for collecting and sending potential and current signals to a data processing terminal; a hydraulic brake, which is arranged in the experimental water filling area and used for stirring the simulation water; the hydraulic brake is not turned on in the static water environment simulation, and is turned on in the dynamic water environment simulation.
