2、要作用。認(rèn)為在煤層注水階段表面活性劑的加入降低了液體表面張力和注水壓力,使注水速度加快,煤體得到均勻潤濕;在水合物誘導(dǎo)階段表面活性劑的膠束化增加了瓦斯氣體的溶解度,促進(jìn)了氣體在溶液中過飽和,推動(dòng)了水合物晶核生長,縮短了誘導(dǎo)時(shí)間;在水合物生長階段表面活性劑膠束對溶于其中的氣體分子和吸附于其周圍的水分子的束縛作用,相當(dāng)于降低了體系的溫度,改變了水合物生成熱力學(xué)條件。關(guān)健詞:乩斯含量;突出預(yù)測;敏感性;預(yù)測深度中圖分類號:TP028.8文獻(xiàn)標(biāo)識(shí)碼:AExperimentalstudyonthenewtechnologyofoutburst
