高精度冷拔技术在地质管材加工中的应用

Application of High Accuracy Cold Drawing Tech. in Geological Pipe Process

摘要:

绍了高精度冷拔技术的特点及意义，结合“科钻一井”施工中使用的大直径薄壁单动双管取心钻具中的岩心内管拔制工艺，阐述了高精度冷拔技术在地质管材加工中的应用前景。

Abstract:

The specialty and significant of high precision cold drawing techniques were introduced. The application prospect of high accuracy drawing techniques in geological pipe process was expounded, based on the inner barrel process techniques of large diameter and thin wall double tube core barrel used in Well CCSD-1.
