摘要

摘要: 为了更好地理解沉积物中孔隙毛细管压力和水合物饱和度的关系，论文提出了一种新的方法。首先，测定了细颗粒石英砂中甲烷水合物的相平衡。根据相平衡数据，计算了孔隙毛细管压力和甲烷水合物的饱和度。结果表明细颗粒石英砂中由于孔隙水活度的降低，甲烷水合物的相平衡发生改变。分析认为孔隙水活度的降低是由于石英砂颗粒表面基团、负电荷性以及孔隙毛细管压力共同所致。随着甲烷水合物饱和度的增加，孔隙有效空间减小，孔隙毛细管压力随之增加。由于水合物生长的随机性特点，孔隙压力-饱和度关系还无法定量描述。

Abstract: To better understand the relationship between the pore capillary pressure and hydrate saturation in sediments, a new method was proposed. First, the phase equilibria of methane hydrate in fine-grained silica sands were measured. As to the equilibrium data, the pore capillary pressure and saturation of methane hydrate were calculated. The results showed that the phase equilibria of methane hydrates in fine-grained silica sands changed due to the depressed activity of pore water caused by the surface group and negatively charged characteristic of silica particles as well as the capillary pressure in small pores together. The capillary pressure increased with the increase of methane hydrate saturation due to the decrease of the available pore space. However, the capillary-saturation relationship could not yet be described quantitatively because of the stochastic habit of hydrate growth.
