| 摘 要： | 基于水合物储层电阻变化的测井技术已在水合物勘探领域广泛应用，在水合物实验模拟研究中，电阻法监测水合物生成与分解过程同样是一种有效的技术手段。文中介绍了以电阻法为核心监测手段的天然气水合物合成模拟实验装置在多孔介质体系中的应用。概述了阻抗测试系统的基本组成及工作原理，并依据实验过程中体系阻抗和温度的变化将水合物生成过程分为5个阶段。分析结果表明，在5个阶段的反应过程中，阻抗的变化都能得到很好的解释。这说明电阻探测是天然气水合物模拟实验中的一项有效的探测技术。

| Abstract: | Because of the broad application of the well logging based on the change of electrical resistance in the hydrate reservoir,the resistance detecting technology used to study of the formation and decomposition of the hydrate is also an effective means.In this paper,a suit of resistance detecting device is applied to the experimental study of the nucleation process of hydrate in porous media.The basic constitution and mechanism of this device is summarized,and according to the change of the resistance and temperature,the hydrate formation process can be divided into five stages.All the experimental results reveal that the change of the resistance in the five stages can be successfully explained and the resistance detecting technology is effective when it is applied to the experimental study of gas hydrate. |
