摘　　要：为了探讨多孔介质中天然气水合物原位形成规律性,进行了将冰粉和石英砂混合并形成天然气水合物的实验研究。实验结果表明,在这种情况下能形成稳定均匀的水合物;冰成天然气水合物的过程是气固反应过程,过程包括吸附、催化、络合、结晶过程。In order to probe into laws on formation of natural gas hydrates in porous medium, natural gas hydrates have been formed through mixtures of ice powers and quartzes in experiments. Results in the experiments show that symmetrical and steady hydrates have been shaped; its process on formation of natural gas hydrates from ice is the course on reaction of solids and gases, which contain adsorption, catalysis, complexation and crystallization.
