Attenuations of different types of gas hydrate cementation in fluid-saturated porous solids are discussed. The factors affecting estimation of gas hydrate and free gas saturation are analyzed.
The three-water( TW) conduction model bases on the theory whoseconductive path is paralleled by free water, micro-porous water and clay bound water.
三水导电模型系基于岩石的导电路径是由自由流体水、 孔隙水和粘土束缚水并联而成的理论。

Owing to their giant specific area, the porous media are of a relatively strong adsorption capacity and the fluid exists as two states, i. e. adsorption state and free state.
