Magnetic control fidelity coring method and system based on multi-field coupling intelligent optimization

Abstract

This invention discloses a magnetically controlled high-fidelity coring method and system based on multi-field coupling intelligent optimization, belonging to the field of intelligent sampling control technology. The method includes: acquiring multi-source heterogeneous drilling data of the target well section, extracting features, and outputting an in-situ environmental parameter matrix of the deep rock mass; based on the in-situ environmental parameter matrix, inputting the multi-directional high-fidelity coring requirements into a deep geological digital twin model to generate global topological constraints and construct a high-fidelity objective function; constructing a basic control parameter matrix, inputting it into a multi-field coupling mechanism model, calculating the multi-field predicted state space, and using minimizing the multi-field predicted state space and the high-fidelity objective function as the optimization objective; calculating the optimal control parameter matrix within the current control cycle within the global topological constraints; performing signal decoupling and physical mapping to drive dynamic high-fidelity adjustment of each unit, achieving lossless transfer of the in-situ state of the core. The method of this invention combines a multi-field mechanism model and algorithm optimization to achieve multi-dimensional dynamic high-fidelity synergy.
