Abstract
Fractures and pores coexist in carbonate reservoirs, and this complex pore structure has a significant impact on acoustic logging. This paper studies the variation of acoustic velocity in carbonate samples based on acoustic rock physics experiments. At the same time, a theoretical gas-bearing reservoir identification template is established based on the elastic theory of porous and fractured media, and the gas-bearing reservoir identification template is calibrated with acoustic velocity experimental data on. Based on the above research, a quantitative identification template for gas-bearing reservoirs is established. The case study has verified the reliability of the gas-bearing carbonate reservoir identification method.
