Application of Resistivity Measurement in the System of Sediment-Brine-Methane Hydrate
电阻率测试技术在沉积物－盐水－甲烷水合物体系中的应用

Using home-made one-dimensional experiment system of natural gas hydrate(NGH),the feasibility of the resistivity measurement technique in the sediment-brine-methane hydrate system was validated by analyzing the change of resistivity,pressure and temperature during the process of the NGH formation.Results show that the nucleation and nucleus growth during NGH formation can be clearly observed from the resistivity change.When NGH begins to nucleate,the resistivity decreases due to the consumption of water and...
