AI Technical Summary
Existing technologies lack simple and effective methods for rapid quantitative calculation of rock pore throat coordination number, making large-scale application difficult. Furthermore, existing methods are costly and time-consuming.
Mercury intrusion curves of rock samples are obtained by mercury intrusion experiments. The logarithmic values of the dynamic parameters of mercury intrusion are calculated and linear regression fitting is performed. The pore throat coordination number of the rock is calculated using the pore fractal dimension. This provides a method and apparatus for calculating the pore throat coordination number of rocks based on the pore fractal dimension.
It enables rapid quantitative calculation of rock pore throat coordination number, reduces technical threshold and application cost, reflects the complexity and diversity of pore throat structure, and guides oil and gas exploration and development and reservoir characteristic evaluation.
