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(guó)海洋工程(英文版)   ISTICEISCI Journal: CHINA OCEAN ENGINEERING 年,卷(期): 2005, 19(1) 分類(lèi)號(hào): Keywords: pressure tight sampling    deep-sea    sediment    gas hydrate    piston corer    機(jī)標(biāo)分類(lèi)號(hào): V27 TH1 機(jī)標(biāo)關(guān)鍵詞: working principle    gas hydrate    rules of 基金項(xiàng)目: 國(guó)家高技術(shù)研究發(fā)展計(jì)劃(863計(jì)劃) Pressure Tight Piston Corer-A New Approach on Gas Hydrate Investigation[期刊論文]  中國(guó)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.
