Abstract

The invention relates to an experiment set, in particular to an acoustic response characteristic simulation experiment set. The acoustic response characteristic simulation experiment set for seabed gas transfer and aquo-complex generation is characterized by comprising a pressure control system, a temperature control system, a detection system, a high-pressure reactor and a computer acquisition system. The pressure control system is communicated with the high-pressure reactor, the high-pressure reactor is arranged in the temperature control system, and the detection system is arranged in the high-pressure reactor and connected with the computer acquisition system. Combined with the bender element detection technology and time domain reflectometry (TDR), the acoustic response characteristic simulation experiment set can monitor change situations of acoustic parameters and aquo-complex saturability in the process of gas transfer and aquo-complex generation in real time, obtained experiment results are closer to seabed environment, and acoustic response characteristic research on generation of aquo-complex with different gas fluxes can be achieved.

Description

technical field [0001] The invention relates to an experimental device, in particular to an acoustic response characteristic simulation experimental device. Background technique [0002] At present, according to different experimental devices, hydrates can be formed in sediments in at least four ways, that is, natural gas is passed into the following types of sediments: (1) sediments containing partially saturated water; (2) sediments containing saturated water ; (3) sediments containing ice particles; (4) hydrates formed in sediments in the form of dissolved gas. The hydrates formed in these four ways all simulate the natural growth process of hydrates to a certain extent, but there are differences. For example, for the first three methods, most of the gas is in the upper part and the sediment system is in the lower part, which cannot truly reflect the process of gas moving upward from the seabed at a certain flow rate. Moreover, hydrates formed by different hydrate forma...
