| titleOfInvention | Natural gas hydrate reservoir information evaluation method and application thereof |
| abstract | The invention belongs to the technical field of natural gas hydrate reservoir exploration and discloses a natural gas hydrate reservoir information evaluation method and application thereof. Based on a two-phase medium theory, a plurality of natural gas hydrate reservoir models are generated from a micro-mode of the natural gas hydrate, reservoir porosity, hydrate saturation and reservoir thickness; and accurately depicting an AVO curve of the natural gas hydrate model by using a Brekhovski equation, and establishing indirect connection between AVO marks of a typical hydrate reservoir and rock physical parameters of the reservoir, thereby realizing prediction and evaluation of the hydrate reservoir. According to the invention, a Brekhovski equation considering the thickness of the thin layer is used as a basic formula, the limit of the semi-infinite medium assumption of the Zoeppritz equation is avoided, the calculation of the thin layer AVO curve is more accurate, and the prediction and evaluation accuracy of the hydrate reservoir is improved. |
