摘　　要：特低渗储层的测井响应特征与常规储层不同。测井响应值难以有效表征孔隙中的油气,不同品质储层间的差异性不明显.利用单一的测井解释方法容易引起多解性和模糊性,测井参数解释难度大,油气识别非常困难.为了更好地实现特低渗储层的测井精细评价,提升测井解释的符合率,本文在大量文献调研的基础上,依托前人的研究成果,详细归纳总结了裸眼井和套管井的测井系列之后,对其特低渗储层的常规测井评价方法及其优缺点进行了系统梳理和深入剖析,并探讨了核磁共振测井、高分辨率阵列感应测井、电阻率成像测井等新技术和非线性数学方法在特低渗储层中应用状况.最后基于特低渗储层地球物理测井技术的发展现状,指出了当前测井评价技术面临的困难和问题,并展望了特低渗储层地球物理测井技术的发展趋势.The lower permeability logging responses are quite different from the normal reservoir logging, in which the logging response value is difficult to reflect effectively the oil and gas characterization of porosity, and the differences between different quality of the reservoir is not obvious. The past researches had shown that using single logging method was easy to cause multiplicity and fuzziness, more difficult to explain logging parameters and recognize the hydrocarbon reservoir. For the purpose of achieving the accuracy of logging valuating lower permeability reservoirs, the research results were analyzed and succeeded, the definition of lower permeability reservoirs in home and abroad was cleared on the base of abundant documents and surveying and studying. And based on the development of geophysical logging for lower permeability reservoirs both in China and abroad, the authors generalized and summarized the logging methods, the technical systems and the techniques of logging evaluation process of lower permeability reservoirs, as well as their merits and faults. And then the new logging techniques and thinkings were probed, such as NMR, HRAI and FMI could effectively evaluate the lower permeability reservoirs. This paper discussed some difficulties and problems concerning geophysical logging for evaluating lower permeability reservoirs and its future development orientation.
