【摘要】：天然氣水合物錄井過程中,與振動(dòng)篩相連接的脫氣裝置其脫氣效率非常低,為解決該問題,研制了專用于天然氣水合物錄井的脫氣裝置并對(duì)其性能進(jìn)行了室內(nèi)試驗(yàn)。采用長0.7m、寬0.7m、高1.7m的試驗(yàn)裝置,開展了氣液比10%~30%、轉(zhuǎn)速0.33~1.33r/s條件下的脫氣效率數(shù)值模擬研究和室內(nèi)試驗(yàn)。研究發(fā)現(xiàn),在相同轉(zhuǎn)速條件下,氣液比為30%時(shí)模擬和室內(nèi)試驗(yàn)得出的脫氣裝置的脫氣效率最高;在相同氣液比條件下,轉(zhuǎn)速1.00r/s時(shí)脫氣裝置的脫氣效率最高。研究結(jié)果表明,研制的天然氣水合物脫氣裝置能顯著提高脫氣效率,最優(yōu)工況為氣液比30%、轉(zhuǎn)速1.00r/s。
[Abstract]:In the process of gas hydrate logging, the degassing device connected with the vibrating screen has very low degassing efficiency. In order to solve this problem, a degassing device for natural gas hydrate logging has been developed and its performance has been tested in laboratory. With a test device of 0.7 m in length, 0.7 m in width and 1.7 m in height, a numerical simulation study and laboratory test of degassing efficiency were carried out under the conditions of gas-liquid ratio of 10 to 30 and rotational speed of 0.33~1.33r/s. It is found that the degassing efficiency is the highest when the gas-liquid ratio is 30 and the degassing efficiency is the highest under the same gas-liquid ratio condition when the speed of 1.00r/s is the same. The results show that the gas hydrate degassing device can significantly improve the degassing efficiency. The optimum conditions are as follows: the gas-liquid ratio is 30, the rotational speed is 1.00 r / s.
