Abstract
The present invention relates to disturbance on hydrate reservoirs with different buried depths, in particularly to a disturbance and stability analysis method for hydrate reservoirs with different buried depths. Preparing a series of stable hydrate systems parallel to a hydrate phase equilibrium curve, wherein both of the porosities and the hydrate saturations of various hydrate systems are consistent, but the buried depths are different; disturbing the series of hydrate systems prepared in the first step, conducting disturbance under different conditions aiming to the hydrate systems with different buried depths; analyzing the stability of the hydrate reservoirs. By controlling the disturbance condition, the hydrate systems with different buried depths may be decomposed along the hydrate phase equilibrium curves thereof or in the hydrate unstable regions; and the decomposition productivity difference between the hydrate reservoirs with different buried depths may be intuitively and scientifically simulated and analyzed.
