| titleOfInvention | Visual core model micro-displacement dynamic observation method |
| abstract | The invention belongs to the technical field of oilfield development, and particularly relates to a visualized core model micro-displacement dynamic observation method which comprises the following steps of 1, manufacturing a visualized core model by using a core slice, saturating formation water containing a nano fluorescent material A after vacuumizing the visualized core model, then displacing saturated formation crude oil, and shooting an original oil-water distribution picture by using a fluorescence microscope; 2. injecting a displacement fluid containing a nano fluorescent material B into the rock core to perform a displacement experiment, and shooting a distribution image of the fluid inside the rock core in the displacement process; 3. an MATLAB software programming program is utilized to convert the original pictures shot in different stages in the first step and the second step into gray level pictures and enhance the picture effect of the gray level pictures; 4. analyzing the processed picture by using MATLAB software, and determining the pixel value of the region occupied by the fluid to be characterized for subsequent statistics; 5. and (3) using MATLAB software to write a program to count the oil-containing areas of the visual model before and after displacement. |
