| Summary | Similar to shale gas, tight sandstone gas is also one of the two main exploration areas in current unconventional natural gas, and it is an important future source to replace conventional oil and gas resources. However, accurate prediction of favorable reservoir space is currently the main bottleneck in the exploration and development of tight sandstone oil and gas. In order to analyze and study the distribution patterns and characteristics of underground tight sandstone gas, this paper first calculates three-dimensional forward simulation parameters based on a rock physics model established in the study area. Then, three-dimensional forward modeling of tight sandstone reservoirs with different porosities and gas saturations is conducted using the time-domain spectral element method. Finally, through comparative analysis of the forward modeling results, relatively ideal conclusions are obtained, providing a theoretical basis for subsequent relevant inversions in the area. |
