摘要 测量了在温度周期变化下的含天然气水合物沉积物的电阻率。在温度震荡过程中,电阻率测量能检测到水合物或冰的二次形成。实验证明,温度震荡能促进分散型水合物在沉积物孔隙中的形成。经过多次温度震荡后,孔隙水大部分能转为水合物,在1.2℃时,水合物最终饱和度为78.2%,其含水合物沉积物的电阻率为12.0ohm.m。 We have conducted a laboratory experiment to measure the electrical properties of fully saturated sediments by synthesized methane hydrate under cyclic temperature.In the cyclic temperature testing,the electricity resistivity was used to detect the secondary formation of hydrate or ice.The experiment indicated that temperature cycling may accelerate the accumulation of disseminated hydrate in the pore space of sediments.After several temperature cycles,most of free water in the pore space of sediments transferred into the gas hydrate,and the electrical resistivity of sediments containing gas hydrate increased from 3.6ohm.m to 12ohm.m at 1.2 ℃,when the hydrate saturation increased from 13.1%to 78.2%.It is inferred that electrical properties can be used to detect pore-filling hydrate in ocean sediments.
