小直径双侧向电极系密封结构改进

Improvement on the sealed construction of dual laterolog electrodes

双侧向电极系在实际测井作业过程中易发生漏油、渗油现象,通过对其密封结构的分析,找出了泄漏原因,进而对电极系结构实施改进,将原有的双端面径向密封改为双端面轴向密封设计,减少或杜绝了渗漏。

Oil leaking and bleeding phenomena of dual lateral tools easily happen during actual logging operation.According to the analyses of the electrodes hermetically sealed construction,leakage reasons are found out.The new construction are designed by using the axial double-end face seal instead of the original radial double-end face seal.
