摘要
套管电阻率测井刻度系统和其它常规测井刻度系统相比更为复杂,需要能够模拟地层介质参数变化,电流源的变化。文章提出了过套管电阻率测井刻度系统需要解决的主要问题,阐述了刻度系统原理及测量方法,介绍了刻度系统的主要功能和关键电路。本刻度系统的设计不仅可以完成仪器的刻度任务,而且可作为过套管电阻率测井技术的研究试验平台。
Compared with other conventional logging calibration system,cased hole formation resistivity logging calibration system is more complex.It demands to simulate the changes of formation medium parameters and current source.The article brings forward the cased hole formation resistivity logging calibration system and the problems to be solved,expatiates the theorem and the measuring method of the calibration system,introduces the main function and key circuits of the calibration system.The design of calibration system can not only accomplish the calibration of the equipment,but also can be used as the cased hole formation resistivity logging technology testing platform.
