存储式测井仪电源中控短节

Power control cartridge of the through-pipe memorized logging tool

文章介绍了过钻具存储式测井仪电源中控短节的软硬件设计和试验情况。随着存储式测井仪投入到超长井段的水平井、大斜度井等复杂井况生产中,研制的存储式测井仪电源中控短节可以满足井下仪器串仅在测井井段工作的要求,从而节约高成本的高温电池,保证仪器能更可靠有效地完成测井工作。试验表明该仪器具有可靠、硬件结构简单、易维修等特点。

This paper introduces the design and test of the power control cartridge for through-pipe memorized logging. As the through-pipe memorized logging tools being applied in the long interval of horizontal wells and high angle wells with complex well conditions,the power control cartridge was developed to control the downhole tools to be powered only when needed,reducing the high cost of high temperature battery and ensuring the downhole tools to be more reliable and efficient. Actual test shows that the power control cartridge is reliable,simple in hardware structure and easy to maintain,etc.
