摘　　要：自然电位测井是最早用于地球物理勘探测井的电法测井方法之一,能直观判断岩性,计算地层水电阻率,故应用广泛。在实际应用中,由于其容易受到各种原因的干扰常常取不到理想的SP曲线。本文通过针对典型故障分析SP信号通路控制方式,对通路进行合理的方法检测和典型案例分析,探讨ERTT61XA的SP测试方法及维修技巧。spontaneous potential logging is one of the earliest electric logging methods used in geophysical exploration logging,which can directly judge lithology and calculate formation water resistivity,so it is widely used. In practical application,the ideal SP curve is often not obtained because of its easy to be interfered by various reasons. In this paper,based on the typical fault analysis SP signal path control method,reasonable method detection and typical case analysis were carried out for the path,and the SP test method and maintenance skills of ERTT61 XA were discussed.
