Hydrate artificial rock core and preparation method and application thereof |
| abstract |
The invention provides a hydrate artificial core and a preparation method and application thereof. The hydrate artificial core comprises mineral powder and a cementing agent; wherein the mineral powder comprises the following components in percentage by mass: 10-20% of chlorite, 20-40% of illite, 10-20% of calcite, 5-15% of mica and 20-40% of quartz; the mass ratio of the mineral powder to the cementing agent is 100: (8-10); the preparation method of the artificial core comprises the following steps: (1) mixing the mineral powder and a cementing agent to form a mixed material; (2) and putting the mixed material into a mold, and further pressurizing, maintaining pressure and curing to obtain the material. The porosity, density and sound wave speed of the artificial core prepared by the method can meet the requirements of preparing a rock framework of a natural gas hydrate stratum in a sea area. |
