Elastic and electrical properties of calcite-cemented artificial sandstones based on a new manufacturing method

Calcite cement is widely existing in sandstones and can significantly affect the elastic electrical properties of sandstones. Accordingly, understanding effects calcite on rock key importance for accurate characterization sandstone reservoirs through seismic electromagnetic surveys. To obtain such knowledge, we design implement dedicated laboratory experiments to investigate porosity P- S-wave velocities resistivity synthetic calcite-cemented made using a new recipe. The experimental results show that generally decrease with increasing when content keeps constant, whereas exhibit complex variation approximately same porosity. Analyses interpretation data indicate are affected jointly by porosity, distribution cement, as well microstructure pore space resulting from different axial stress employed consolidation samples. have revealed mechanisms how sandstones, provided theoretical basis
