利用化学实验方法研究了陆相页岩中常见的矿物以及页岩的三元抽提残渣在模拟地层温度下吸附滞留烃和原油的能力。结果表明,陆相地层中常见的3种主要矿物吸附滞留烃和原油的能力为:伊利石>蒙脱石>碳酸盐岩,并且矿物吸附滞留原油的能力要远远大于其对烃类的吸附滞留能力。主要包括无机矿物和干酪根的页岩三元抽提残渣对于烃类和原油的吸附滞留能力要远远大于混合矿物,计算结果表明,矿物对于烃类和原油的吸附滞留能力约在0.20~3.13 mg/g之间,而干酪根对于烃类和原油的吸附滞留能力约在55~150 mg/g之间。

The hydrocarbon and oil adsorption ability of minerals in continental shales and methanol-acetone-benzene (MAB) extracted shale residues were studied experimentally under formation temperatures. Hydrocarbon and oil adsorption ability decreases from illites to montmorillonites and to carbonates and oil adsorption amount in minerals is greater than hydrocarbon adsorption amount. MAB extracted shale residues, which mainly include minerals and kerogens, show better hydrocarbon and oil adsorption ability than mixed minerals. Minerals can adsorb hydrocarbon and oil at 0.20-3.13 mg/g, while kerogens can adsorb hydrocarbon or oil at 55-150 mg/g.
