| Experiments with Refitted Apparatus of Gas Releasing in the Acid-degassing Method for Marine Sediments |
| In the past, the acid-degassing method was frequently used for conventional oil and gas exploration. On the basis of some experimental research, it is recently proved that the method can also be applied to marine gas hydrate prospecting. The apparatus of gas releasing is the most important component in acid-degassing method, which will affect the efficiency of gas releasing from samples. To meet the characteristics of marine sediment samples with small volume, the apparatus of gas releasing should be refitted. This paper deals with this problem. Based on previous researchers' work, the authors established a refitted apparatus of gas releasing for marine sediments. After a series of conditional experiments with the apparatus, the optimum experimental conditions of gas releasing, such as sample granularity, HCl concentration and reaction duration, are confirmed. The parallel and accuracy experiment results are in accord with the relevant ministerial standards. |
