四参数一体化组合测井仪常见故障排除

Common Malfunctions and Trouble Shooting of 4-parameter Combination Logging Tools

四参数一体化组合测井仪采用曼彻斯特编码传输,仪器可以配接多种地面测井系统,一次下井可同时测取四个参数。介绍了四参数一体化组合测井仪结构及电路原理,对实际使用中出现的常见故障进行了原因分析,给出了一些行之有效的故障排除方法。

The 4-parameter integration logging tool uses manchester code transmission. The tool can match various surface logging systems and measure four parameters of well temperature,pressure,casing collar locator and gamma at the same time. This paper introduces the structure and circuit principle of the logging tool,and analyses the common fault which appeared in practice,and raises some effective method of faults exclusion
