The invention relates to a series type underlying free gas hydrate-containing reservoir simulation device and method. The series type underlying free gas hydrate-containing reservoir simulation device comprises a reaction kettle system, a gas supply system, a water supply system, a temperature control system and a data monitoring system. The reaction kettle system is used for simulating an underlying free gas hydrate-containing reservoir; the gas supply system is connected with the reaction kettle system and is used for injecting gas into the reaction kettle system; the water supply system is connected with the reaction kettle system and is used for injecting water into the reaction kettle system; the temperature control system is connected with the reaction kettle system and is used for controlling the temperature and the pressure in the reaction kettle system; and the data monitoring system is connected with the reaction kettle system and is used for monitoring the state in the reaction kettle system and transmitting the monitored state data to the temperature control system. According to the series type underlying free gas hydrate-containing reservoir simulation device and method, the natural gas hydrate-containing reservoir containing underlying free gas can be simulated before exploitation, so that the gas phase and hydrate-containing phase distribution state of the actual reservoir is reflected, and a data basis is provided for evaluating the natural gas reserves of the hydrate-containing reservoir and the exploitation economic benefits.
Description
technical field [0001] The invention relates to the field of natural gas hydrate exploitation experiment simulation, in particular to a series simulation device and method for reservoirs containing underlying free gas hydrate. Background technique [0002] It is difficult and costly to obtain undisturbed hydrate sediment cores. During the process of drilling and coring, the change of load will cause the disturbance of the sediment structure; the change of temperature and pressure will make some hydrates decompose. The obtained cores cannot truly reflect the reservoir conditions of hydrate sediments. The artificially synthesized hydrate sediment samples in the laboratory have the characteristics of controllable parameters and low cost. In the laboratory, according to the geothermal, geomorphological and sedimentary conditions of my country's sea areas and permafrost regions, parameters such as sediment particle size distribution, initial porosity, hydrate formation temperat...
