| titleOfInvention | A kind of rock-like material for simulating the heterogeneity of reservoir rock and preparation method of specimen |
| abstract | The invention relates to a rock-like material for simulating the heterogeneity of reservoir rocks and a preparation method for a test piece, belonging to the field of rock-like material preparation. Including: measuring the heterogeneity, particle size distribution and mechanical parameters of the reservoir rock; analyzing the influence of the particle size ratio on the heterogeneity of the reservoir rock and the sensitivity of the mechanical parameters of the rock-like material, using the quartz sand particles The particle size is the index, and the gradation model and mathematical relationship curve of rock-like materials with different degrees of heterogeneity are established under the conditions of different particle size ratios; A schematic diagram of the particle size distribution of rock specimen aggregates, select quartz sand particles with corresponding particle sizes for aggregate ratio; use quartz sand particles as aggregate to prepare rock-like specimens, cure and demould. The heterogeneous rock-like material of the present invention can better reflect the controlling effect of particle size on rock heterogeneity, and can more accurately describe the heterogeneity characteristics of complex lithologic strata. |
