【摘要】 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.更多还原

【Abstract】 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.更多还原
