胀管器

梨形胀管器因施工操作简单、耐用性强、成本较低，被广泛应用于油田修井作业。

Pear-shaped casing swage has been widely used in oil field workover operation , due to its simple operation , strong durability and lower cost .

但目前缺乏梨形胀管器整形过程的理论分析模型及结构优化设计的分析方案，因此本文对梨形胀管器整形工艺做了详细的研究。

However , the theoretical analysis model of the shaping process and the analysis of optimization design scheme of the pear-shaped casing swage are rare .
