摘　　要：微电阻率球形聚焦(简称微球)和双侧向(简称侧向)测井仪都是利用电流聚焦进行电阻率测量的常规测井仪器,但由于所探测的深度不同,这两种仪器的聚焦方式以及如何做到精确测量的电路设计各不相同。文章从仪器维修的角度,对这两种仪器分别进行了阐述。Micro spherically focused resistivity tool and dual laterolog tool are conventional logging tools, which survey formation resistivity in using focused current. But in order to extend the different depths of investigation, the pattern of focusing current and the design of the circuit for measuring accurately are different. This paper discusses the two points based on maintenance of equipment.
