摘　　要：论文针对地层水电阻率测井过程中测井电极系探测深度较浅,测井效率比较低的不足,提出了使用三侧向测井电极系的替代方案,并通过对两种电极系工作原理的分析,设计了实验室环境下的对比试验证明方案的可行性。在相同的外部条件下保证为电极系提供电流的电源输出功率相同,测量试验溶液中的电场分布情况,根据测量数据做出溶液中电场电位分布图和等势线。结果表明,在相同的电源输出功率条件下,采用三侧向测井电极系激励电流聚焦效果明显,测量深度较大,测井效率较高,弥补了原有测井电极系的不足。Due to the water resistivity logging electrode system detecting depth is shallow, logging efficiency is low, we put forward using three lateral logging electrode system as an alternative. By analyzing the working principle of two kinds of electrode system, designed a contrast experiment in the laboratory environment prove the feasibility. Under the same exter- nal conditions, ensure the output power of each electrode system same and stable, measure the electric field distribution of the test solution, use measurement data draw figures of electric potential distribution and contour lines. According to the re- suit, under the same output power of electrode system, the focus effect of exciting current of three lateral logging is obvious, detecting depth is deep, logging efficiency is high, made up the shortage of ordinary resistivity logging electrode system.
