为研究黏土矿物类型对页岩油中轻烃和重烃数量及变化规律的影响,借助人工合成的十六烷基三甲基氯化铵—蒙脱石和十六烷基三甲基氯化铵—伊利石有机黏土,使用压力机对合成有机黏土的柴油饱和样进行超压下孔缝排烃模拟实验。结果表明：在深层,纯黏土矿物选择残留重烃,纯蒙脱石较纯伊利石残留烃量更大;十六烷基三甲基氯化铵的介入直接使蒙脱石选择性残留轻烃,但没有改变伊利石的选择性残留特征;含十六烷基三甲基氯化铵的蒙脱石黏土页岩残留烃品质较好,多为轻烃化合物,十六烷基三甲基氯化铵含量对其影响相对较小;含十六烷基三甲基氯化铵的伊利石黏土页岩残留烃品质较差,多为重烃化合物,十六烷基三甲基氯化铵含量越多越利于残留烃的保存。

英文摘要：

In order to study the influences of the clay mineral types on the numbers of light-heavy hydrocarbons and change rules in the shale oil,with the help of the artificially synthesized montmorillonite organic clay with cetyltrimethylammonium chloride（ CTAC） and the illite organic clay with CTAC,the simulating experiment of the hydrocarbon expulsion in the hole and fracture under the overpressure was conducted for the diesel oil saturatedsamples of the synthetic organic clays by the pressing machine. The experimental results show that the pure clay minerals tend to select to remain the heavy hydrocarbons,and the residual hydrocarbon content in the pure montmorillonite is more higher than that in the pure illite; the intervention of CTAC directly make the montmorillonite select to remain the light hydrocarbon,but it has little influence on the variation of the selectivity in illite; the quality of themontmorilloniteclayshale with CTAC is pretty better in the residual hydrocarbon,which mainly includesthe light hydrocarbon compounds,and the effects of the CTAC content are relatively small; whereas for the shale with the CTAC organic matter and illite clay,the residual hydrocarbon is rather poorer in the quality,which mainly includesthe heavy hydrocarbon compounds,and the higher of the CTA Ccontent is,the much favorable for the residual hydrocarbon preservation.
