一种测定天然气水合物沉积物体变的三轴试验装置
摘要：
本发明提供了一种测定天然气水合物沉积物体变的三轴试验装置。该装置包括由外罩筒和底座组成的密闭压力室；所述密闭压力室内设有内罩筒，所述内罩筒固定在所述底座上；所述底座上设有至少两个进出油孔，一个所述进出油孔开口于所述外罩筒与内罩筒之间的环腔，另一个所述进出油孔开口于所述内罩筒的内腔；所述外罩筒与内罩筒的顶部设有活塞；所述活塞上设有排气孔；所述内罩筒的内腔中设有相对应的下压垫和上压垫；所述上压垫与所述活塞的位置相应，所述下压垫固定在所述底座上。
摘要（英）：

The invention provides a triaxial test device for testing the transubstantiation of sediments of a gas hydrate. The device comprises a closed pressure chamber consisting of an outer cover barrel and a base; an inner cover barrel is arranged in the closed pressure chamber; the inner cover barrel is fixed on the base; at least two oil inlet/outlet holes are formed on the base; the opening of one oil inlet/outlet hole is formed on a circular cavity between the outer cover barrel and the inner cover barrel; the opening of the other oil inlet/outlet hole is formed on an inner cavity of the inner cover barrel; pistons are arranged on the tops of the outer cover barrel and the inner cover barrel; exhaust holes are formed on the pistons; a lower pressure pad and an upper pressure pad which correspond to each other are arranged in the inner cavity of the inner cover barrel; the upper pressure pad corresponds to the positions of the pistons; and the lower pressure pad is fixed on the base.
