摘　　要：根据低电阻率油气层的成因,将低电阻率油气层分为四种主要不同的类型,这四种类型的低电阻率油气层除了需要进行常规测井系列外,不同成因的低电阻率油气层应采用不同的新技术测井项目,对于高不动水含量型低阻油气层,将核磁共振测井作为解决这种类型的针对对性测井项目,而MDT测井作为选择性项目;对于粘土附加导电型低阻油气层,将极化率测井作为解决该类低阻问题的针对性测井项目,核磁共振、双频介电、MDT测井作为选择性测井项目;对于砂泥岩间互型低阻油气层,高分辨率感应测井或者阵列侧向测井是解决此类低阻油气层的关键技术;对于盐水泥浆侵入型低阻油气层,可以有针对性的进行过套管电阻率测井,同时在储层物性条件较好时还可以选测C/O或PND测井替代过套管电阻率测井项目,或者根据地面及地下地质情况,选取随钻测井系列.Based on the origins of low resistivity hydrocarbon-bearing reservoirs, the low resistivity hydrocarbon-bearing reservoirs are divided into four main kinds. Besides conventional logging suite is carried on for the low resistivity hydrocarbon reservoirs, the different new technology logging items should be adopted. For the high irreducible water saturation low resistivity hydrocarbon-bearing reservoirs, the nuclear magnetic resonance logging （NMR） is a pertinent item solving this type, and MDT logging is a choice. For the low resistivity reservoirs resulting from the added conductivity of shales, the polarizing rate logging is pertinent item solving this type, but NMR logging, the dual frequency dielectric, and the MDT logging are suitable. For sand and shale interbeded low resistivity hydrocarbon-bearing reservoirs, high resolution induction（HDIL or AIT） logging or array laterolog is the key technology to solve this type. For the low resistivity hydrocarbon-bearing reservoirs which are deeply invaded by brine-nud, the cased-hole formation resistivity logging（CHFR） can be carried out. Meanwhile in the condition of good property of the reservoirs, C/O or PND logging can replace CHFR logging, or according to earth surface and subsurface geology condition, logging while drilling can be an approach.
