抚顺油页岩干馏渗透实验研究

为了为地下原位开采页岩油提供一定的理论依据,在高温高压蒸汽作用下进行了油页岩的干馏实验,以及干馏后油页岩的三轴渗透实验.结果表明:①高温高压蒸汽可以有效地干馏油页岩并带走页岩油;②高温高压蒸汽作用下油页岩会产生大量的裂缝,从而提高油页岩的渗透性;③油页岩干馏后渗透系数是体积应力和孔隙压的函数,其关系仍然服从指数规律.实验结果对地下原位开采页岩油有一定的指导意义.

Dry distillation and seepage experiments of Fushun oil shale

In order to provide the theoretical basis for mining the shale oil in situ,the dry distillation experiment of the oil shale at high-temperature and high-pressure is carried out,and then the triaxial seepage experiment of the dry distillation oil shale is finished.It is shown that,1) high-temperature high-pressure vapor can effectively dryly distillate the oil shale and carry away the shale oil;2) under high-temperature and high-pressure,the oil shale will produce a lot of fracture,which can improve the permeability of the oil shale;3) after dry distillation,the permeability coefficient of the oil shale is the function of volumetric stress and pore pressure,and it is an exponent function.
