Results of core filtration tests to assess the reduction in permeability due to colloid migration

Results of filtration tests of three core samples, filtered liquid - deionized water and kerosene. Filtration installation - AFS-300. Filtering conditions inside files. Core samples are registered in IGSN, the numbers and type of fluid are indicated in the file name. Prior to filtration, the samples are saturated under vacuum for 24 hours. Before filtration, the samples were kept in an AFS-300 core holder at confining and pore pressure for 24 hours.本次数据集涵盖三种岩心样品分别以去离子水与煤油作为过滤流体的过滤试验结果。试验采用的过滤装置为AFS-300型设备，详细过滤条件详见各配套文件。所有岩心样品均已完成国际地质样品编号（International Geo Sample Number，IGSN）注册，流体类型与对应样品编号可通过文件名直接查询。过滤试验正式开展前，样品需先经24小时真空饱和处理；随后将样品装入AFS-300型岩心夹持器，施加围压与孔隙压力并静置24小时，再启动过滤试验。
