铣磨工具是油田较广泛使用的实用工具之一。通过近几年对现场使用情况的调查和据各油田的反映来看,铣磨工具的发展速度已落后于其它打捞工具的发展速度,成为油田修井工具中的薄弱环节。目前现场使用的铣磨工具在本体设计、制造和焊接工艺等方面主要存在如下问题: Milling tools are one of the more widely used utilities in the field. Through the investigation of field usage in recent years and according to the reflection of each oilfield, the development speed of milling tools lags behind that of other fishing tools and becomes the weak link in oilfield workover tools. Currently used on-site milling tools in the body design, manufacturing and welding processes mainly exist the following problems:
