摘要
There are good prospects of natural gas hydrate resources on the northern slope of the South China Sea. However, whether or not the gas hydrate will play a part in our energy strategy lies in whether or not it can be effectively extracted. Such real production will mostly rely on the full assessment of gas production potential from the marine hydrate deposits. Unfortunately, the relevant research costs are surprisingly high in the field tests alone, while the experimental simulation of hydrate production under high pressures is limited to a small scale presently, and can not fully characterize the gas production potential on a substantial reservoir scale. Thus it is the only way for hydrate production engineers to establish mining plans and calculate gas production potentials through numerical simulation. Because the gas production potential, however, is closely related to the complexity and dissimilarities of the hydrate reservoir characteristics, the production capacities must be evaluated by using different production methods for different types of hydrate reservoirs, which will inevitably raise the research cost. Therefore, based on the response relationship between hydrate production potential and different geological parameters of hydrate reservoirs, this paper discussed the geological parameters, which are most closely related to the gas production potential. Thus, a set of the objectives, contents and methods were presented for the geological evaluation indexes of marine hydrate production potential, providing the theory and methodology for the rapid evaluation of gas production potential in the marine gas hydrate reservoirs.
