Latest Patents

Changhong Chu's latest patents include two innovative methods. The first patent is titled "Method for reconstructing pore structure of core with micro-CT (computed tomography)." This method utilizes a FIB-SEM (Focused Ion Beam-Scanning Electron Microscope) experiment to establish a relationship between the grey level of a micro-CT image and the porosity of the core. By assigning porosity to each pixel in the micro-CT image, this method provides a soft segmentation approach for digital reconstruction of the pore structure, enhancing the accuracy of the digital pore structure model.

The second patent is "Isotope nuclear magnetic method for analyzing ineffective water absorption of rock pores." This method involves saturating core pores with a wetting phase fluid and analyzing the resulting Tspectrum. By simulating a water injection process and analyzing the content of immobile water, this method identifies the ineffective water absorption portion of rock pores, providing valuable insights into rock behavior.
