摘    要:在某石油储备库吕荣压水试验中,通过现场试验测量了测试管路的摩阻,并对测段的渗透吕荣值进行了校准。分析认为所测试的地下工程岩体渗透性总体不强,尤其是50m往下的中深部岩体,其透水吕荣值一般小于0.2Lu。试验中不剔除摩阻直接计算获得的吕荣值都略偏小(减小幅度在1.21%~10.48%),一定程度上"美化"了岩石的低渗性能。此外发现摩阻剔除在高吕荣值岩体渗透性能评估中尤为重要,对低渗透岩体影响程度要相对小些。

关 键 词:吕荣  压水  摩阻  渗透率

Abstract:During the Lugeon water pressure test in an oil reserve library project,hydraulic friction of the test tube was measured at the test site,and the permeability value of the test sections were calibrated.The results show that the overall permeability of the underground rock is not strong,especially at 50 m deeper down,generally less than 0.2 Lu.All the Lugeon values before having removed its hydraulic friction are less than the true value within the range of-1.21% ~-10.48%.Therefore it highlights the excellen...
Keywords:Lugeon  water pressure test  friction  permeability
