EOS - In the Analysis of Force Balance Conditions for the Formation of Deep Basin Gas

Abstract:

Deep basin gas, which is trapped deep in a basin, is a kind of unconventional natural gas. It is also one of the important unconventional gas resources. In the previous studies of the mechanism of deep basin gas accumulation, force balance and material balance are considered as essential conditions for the formation of deep basin gas reservoirs. However, the gravity of natural gas is not fully taken into account in the analysis of force balance. In this dissertation, the density of natural gas under the condition of underground temperature and pressure is calculated by using the EOS. The result shows that the density of natural gas cannot be neglected and the PR EOS is applicable to the analysis of the relationship between the volume of natural gas and the condition of underground temperature and pressure.
