【摘要】：為研究黏土礦物類(lèi)型對(duì)頁(yè)巖油中輕烴和重?zé)N數(shù)量及變化規(guī)律的影響,借助人工合成的十六烷基三甲基氯化銨—蒙脫石和十六烷基三甲基氯化銨—伊利石有機(jī)黏土,使用壓力機(jī)對(duì)合成有機(jī)黏土的柴油飽和樣進(jìn)行超壓下孔縫排烴模擬實(shí)驗(yàn)。結(jié)果表明:在深層,純黏土礦物選擇殘留重?zé)N,純蒙脫石較純伊利石殘留烴量更大;十六烷基三甲基氯化銨的介入直接使蒙脫石選擇性殘留輕烴,但沒(méi)有改變伊利石的選擇性殘留特征;含十六烷基三甲基氯化銨的蒙脫石黏土頁(yè)巖殘留烴品質(zhì)較好,多為輕烴化合物,十六烷基三甲基氯化銨含量對(duì)其影響相對(duì)較小;含十六烷基三甲基氯化銨的伊利石黏土頁(yè)巖殘留烴品質(zhì)較差,多為重?zé)N化合物,十六烷基三甲基氯化銨含量越多越利于殘留烴的保存。
[Abstract]:In order to study the effect of clay mineral types on the quantity and variation of light and heavy hydrocarbons in shale oil, the synthetic hexadecyl trimethyl ammonium chloride montmorillonite and hexadecyltrimethyl ammonium chloride-Illite organic clay were synthesized. The oil saturated sample of synthetic organic clay was simulated by pressure press under overpressure. The results show that in the deep layer, the residual heavy hydrocarbon is selected by pure clay minerals, and the residual hydrocarbon content of pure montmorillonite is higher than that of pure Illite, and the intervention of cetyltrimethylammonium chloride directly results in the selective residual light hydrocarbon of montmorillonite. The residual hydrocarbon quality of montmorillonite clay shale containing cetyltrimethylammonium chloride is better, most of them are light hydrocarbon compounds, and the content of cetyltrimethylammonium chloride has little effect on it. The residual hydrocarbon quality of Illite clay shale containing cetyltrimethylammonium chloride is poor and it is mostly heavy hydrocarbon compound. The more the content of cetyltrimethylammonium chloride is, the better the preservation of residual hydrocarbon is.
