AI Technical Summary

Technical Problem

Existing methods are unable to accurately reflect the pore-throat topology of tight reservoirs with low coordination number and poor connectivity, and it is difficult to make targeted adjustments to the connectivity based on the characteristics of the target reservoir. Local heterogeneous connectivity is limited, and it is not directly geared towards the topology design of fabricable micro/nanofluidic chips.

Method used

By extracting the centroid coordinates of real pore images to construct a triangulation network, optimizing the quality of triangles and intersection edges, and optimizing the network based on the coordination number of pore nodes, a pore throat topology model that conforms to the structural characteristics of tight reservoirs is formed, and a micro/nano fluid control chip design diagram is generated.

Benefits of technology

This improves the accuracy of chip models in reproducing the pore-throat structure of real reservoirs and enhances the reliability of experimental simulations, ensuring the stability and rationality of the generated pore-throat network, which conforms to the topological characteristics of tight reservoirs.
