Pressure Tight Piston Corer—A New Approach on Gas Hydrate Investigation
摘要
A pressure tight sediment sampling technology, which can be introduced into the modification of the piston corer to accommodate the investigation of gas hydrate, is put forward. In this paper, the three basic rules of the technology are analyzed in detail: specimen transferring rule, seal self-tightening rule and semi-active pressure holding rule. Based on these, the structure of the pressure tight piston corer is put forward and its working principle is analyzed. Finally, a pressure tight sediment sampler, to which the same technology is applied, is researched through experiments. Results show that the sampler based on the above-mentioned theory has a good ability in sampling and in -situ pressure holding.
