在低渗透油层中 ,地层渗透率低 ,测试范围有限 ,测试资料解释的渗透率是否代表地层渗透率 ,计算的表皮系数是否真实反映地层的污染及改善程度。若同一层进行过两次以上的测试 ,可以分别将两次测试解释的渗透率和表皮系数进行比较 ;若仅进行过一次测试 ,可将渗透率与岩心分析平 In low permeability reservoirs, the formation permeability is low and the test range is limited. Whether the permeability information, which is explained by the test data, represents the formation permeability or not, and whether the calculated skin factor truly reflects the formation contamination and the degree of improvement. If more than two tests have been performed on the same level, the permeability and skin factor explained in the two tests can be compared respectively. If only one test is performed, the permeability and core analysis level
