REDUCED SCALE NATURAL GAS HYDRATE RESERVOIR PHYSICAL CHARACTERISTICS REPRESENTATION APPARATUS AND METHOD

摘要

Disclosed are a reduced scale natural gas hydrate reservoir physical characteristics representation apparatus and a method. The apparatus comprises a reaction kettle, a horizontal well pipe (24), and a vertical well pipe (8). The reaction kettle comprises an upper kettle lid (201), a lower kettle lid (202), and a kettle body (200), the upper kettle lid (201) and the lower kettle lid (202) being sealed and closed against two ends of the kettle body (200) to form a sealed cavity. The reaction kettle also comprises a side vertical well assembly and a temperature and pressure resistor assembly, the side vertical well assembly and the temperature and pressure resistor assembly being configured to penetrate the reaction kettle from the upper kettle lid (201) to the lower kettle lid (202). With the method, according to the lattice data of the pressure measurement pipe, the temperature measurement pipe, and the sensor of the resistivity measurement post, a data processing software is used to generate a change cloud graph, so as to observe in real time the temperature field, the pressure field, and the resistivity field in the reaction kettle, thereby simulating the hydrate distribution field, pressure field, and temperature field in the reaction kettle. The representation apparatus and method can represent in real time and in situ the heat transfer, mass transfer, and hydrate phase transition during the hydrate mining process.
