| 摘 要： | 本文在推导热力作用下水合物地层温度分布基础上,发展了评价热力法开采天然气水合物的热效率(用于水合物分解的热量与输入总的热量之比)和能量效率(即输出能量与输入能量之比)的模型.模型分析表明,水合物地层热物性参数以及水合物饱和度决定了热力法开采的能量效率.在注入蒸汽开采初始条件下,能量效率可以达到7.0.

| Abstract: | Based on the derivation of the temperature distribution of hydrate bearing sediments under thermal stimulation, a model in evaluating the thermal efficiency (the ratio between the heat for hydrate dissociation and total input heat) and energy ratio (the ratio between the output energy due to the combustion of produced gas and total input energy) of natural gas hydrate production has been developed. The mode suggested that the thermal properties of hydrate bearing sediment and hydrate saturation are key factors in deciding the energy ratio. Under the production condition of steam injection, the energy ratio can reach 7.0. |
