Abstract

Considering the charateristics of marine gas hydrate containing area such as faulted structures are developed and reservoir distribution is not clear, this paper uses the recursive inversion method based on deconvolution to carry out the poststack constrained sparse spike inversion without well data by integrating the well log responses of gas hydrates in adjacent areas. The inversion result has been sculptured in order to find out the gas hydrate forming pattern and characterize the spatial distribution of gas hydrates and further predict the favorable area containing gas hydrates. The research result shows that the research area has obvious gas chimney responses, and the deep gas take gas chimneys as their migration pathways and migrate all the way to somewhre in the top to form gas hydrate reservoirs, which can provide practical reference and basis for future exploration and production of marine gas hydrates.
