Pressure Tight Piston Corer-A New Approach on Gas Hydrate Investigation
Abstract：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. 作者： Author： QIN Hua-wei Gu Lin-yi LI Shi-lun ZHU Liang CHEN Ying 作者單位： State Key Laboratory of Fluid Power Transmission and Control, Zhejiang University, Hangzhou 310027, China 期 刊： 中國海洋工程（英文版） ISTICEISCI Journal： CHINA OCEAN ENGINEERING 年，卷(期)： 2005, 19(1) 分類號： Keywords： pressure tight sampling deep-sea sediment gas hydrate piston corer 機標(biāo)分類號： V27 TH1 機標(biāo)關(guān)鍵詞： working principle gas hydrate rules of 基金項目： 國家高技術(shù)研究發(fā)展計劃(863計劃) Pressure Tight Piston Corer-A New Approach on Gas Hydrate Investigation[期刊論文] 中國海洋工程（英文版） --2005, 19(1)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.
