AI Technical Summary
Existing core testing systems suffer from several problems in simulating real underground multi-physical and chemical field coupling environments: lack of in-situ quantitative characterization of hydraulic fracturing processes, lack of online monitoring of microbial and hydrochemical parameter evolution, and lack of quantitative description and prediction of multi-physical and chemical field coupling effects.
An experimental simulation system for the five-field coupling effect of deep water storage was designed, including an injection unit, a core clamping and multi-field coupling simulation unit, an effluent fidelity collection and control unit, and an online detection unit. It integrates multi-field application components, dual-modal monitoring components, and an integrated control and data fusion platform, realizing process visualization, sampling fidelity, and mechanism quantification.
It enables in-situ, high-fidelity sampling of fluids in deep-reduced environments, ensures oxygen-free protection during the sampling process, improves the measurement accuracy of hydrodynamic field parameters under extremely low flow velocity conditions, constructs a multi-field coupled constitutive model, provides three-dimensional perception of acoustic emission damage point clouds and resistivity fluid distribution, and ensures the homogeneity and stability of the injected fluid and high accuracy of flow measurement.
