Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing:
[0026] The invention comes from the project of the National Natural Science Foundation of China "Skeleton Conductive Low Resistivity Oil Layer Artificial Rock Sample Experiment and Research on Conductive Law and Conductive Model" (approval number: 41274110). The content of the present invention is related to three aspects of this rock sample production technology, namely: the determination of the quality of pyrite, clay and quartz sand in the skeleton conductive dispersed argillaceous sandstone, the compression of the skeleton conductive mixed argillaceous sandstone and the experimental rock sample molding technology.
[0027] Depend on figure 1 As shown, this artificial rock sample of skeleton conductive mixed argillaceous sandstone includes a cylindrical rock sample core, which is unique in that: the rock sample inner core is cut by a small semicircle of mudstone and a l...
