摘要
PROBLEM TO BE SOLVED: To provide a measuring apparatus and measuring method, capable of easily measuring the crystal growth pressure of a gas-hydrate, and a method capable of effectively estimating the depth of a surface layer type methane hydrate distributed in a water bottom sediment in a water bottom and easily performed.;SOLUTION: An apparatus for measuring the crystal growth pressure of a gas-hydrate comprises: a test chamber 12 for supplying water W and raw material gas G to form a gas-hydrate crystal; a pressure control part 24 for setting the inside of the test chamber 12 to a predetermined pressure; and temperature control parts 28 and 30 capable of providing a temperature gradient to the test chamber 12. The test chamber 12 is constituted so that the crystal formed in the test chamber is grown against the energizing force of an energizing member 40 and includes a load measuring part 42 capable of measuring a load applied to the energizing member 40.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
