Progress in Key Technologies for Handling Natural Gas Hydrate Cores from Ocean Sediments
摘要
Abstract
It is very important to build up a technical system for recovering and handling natural gas hydrate cores from marine and permafrost sediments.As one major part of the system,in-situ handling and testing pressure cores plays an important role in obtaining relative parameters of gas hydrate-bearing sediments and then evaluating and predicting the corresponding behaviors of gas hydrate-bearing sediments in complex setting.On the drilling sites,this part was achieved by designing in-situ core flow plans,controlling pressure and temperature of pressure cores,and in-situ transferring and testing cores.In detail,it includes maintaining pressure and temperature of controlled devices,precise control of pressure cores inside the working chamber,in-situ direct contact tests on pressure cores inside the working chamber,and joint tests on pressure cores by means of the combination of the working chamber with other outside test devices.关键词
