摘　　要：为了提高低阻油层测井识别评价的精度,本文基于大量的文献调研,通过对前人研究成果的吸收继承,梳理了国内外关于低阻油层的定义,归纳总结了低阻油层一般成因机理,研究了低阻油层的常规测井响应特征及其一般识别评价方法,进而探讨了低阻油层识别评价测井新技术和新思路.研究表明,低阻油层一般成因和影响因素包括十个方面;低阻油层常规测井响应呈现为高自然伽马、较高声波时差及高中子测井值、自然电位异常幅度低和密度测井值低等特征,低阻油层常规测井响应特征随其成因机理而异;低阻油层一般识别评价方法有九种之多;核磁共振测井、阵列感应测井及MDT等测井新技术可有效识别评价低阻油层;非线性数学方法为低阻油层识别评价提供了新思路.For the purpose of advancing the accuracy of logging identifying and evaluating low resistivity reservoirs, the research result was analyzed and succeeded, the definition of low resistivity reservoirs in home and abroad was cleared on the base of abundant documents published and surveying and studying. The ordinarily origin and mechanism was generalized, and conventional log response feature and evaluating methods were researched, and the new logging techniques and thinking were probed. The study indicates that the contributing factors is including ten aspects, and the logging characteristic of low resistivity mainly includes high gamma ray and acoustic time and neutron log value, and low spontaneous potential and density, the logging features is fit to the mechanism. The research also indicates that the method is about nine kinds and the new logging techniques such as NMR and Array induction log and MDT could effectively evaluate the low resistivity reservoirs. The nonlinearity mathematical methods provide the advancing thinking.
