浅谈H_2S气体对井下测试工具的腐蚀特性及对策

A Brief Introduction for Erosion of H_2S to Down Hole Testing Tools and Its Strategy.

针对含H2 S气井中 ,H2 S对测试工具腐蚀严重情况 ,分析了H2 S等腐蚀介质与地层水共同形成的腐蚀环境对测试工具的腐蚀机理 ,以及温度、H2 S浓度与金属腐蚀速率的关系 ,提出了合理的对策。

In the light of serious erosion situation of testing tools in wells containing H 2S,the paper not only analyses the erosion mechanism to down hole tools under the curcumas commonly produced by medium like H 2S,etc.and formation water,and the relationship between temperature,H 2S density and metal erosion rate,but also suggests a reasonable strategy.
