| 中文摘要 | At present one of hydrate domain research hot spots is the seabed natural gas hydrate mineral resource mechanism. The seabed natural gas hydrate production process is an essential part of this mechanism and is also the base of other applications of hydrates. An experimental system for Simulating seabed leakage system of high speed formation of natural gas hydrate was set up. An ejector was utilized to produce lots of micro-bubbles, which increase the gas-liquid contact area to promote the formation rate of natural gas hydrate. Furthermore, in order to enhance the gas utilization efficiency, a gas circulation is made by the suction force of the ejector, which makes this system much simpler. A heat exchanger was installed in the water circulation loop to take away the heat released by the formation of gas hydrates in order to eliminate heat transfer’s influence on the hydrate formation rate. The experiments illustrate that gas hydrate can form within several minutes under high-pressured (2.0~3.5Mpa) and low temperature (1.5~2.5℃) condition. The experiments of the characteristics of natural gas hydrate formation were carried out at the pressure range of 2.0~3.5Mpa, temperature range of 274.5-275.5K. The experiment illustrated that, under 2℃ and 3Mpa condition, when the carbon dioxide leakage flux is 0.92mol/s.m2, the carbon dioxide spending speed can reach 2.03mol/s. m2. The author compute the production velocity and temperature of Nanhai southeast basin hydrate by the leakage system hydrate growth model in the article. This model establish the hydrate/water/gas three-phase system,and compute the growth velocity by the analysis of system driving influence and boundary condition.At last, compute the hydrate production velocity and temperature change by the model. |
