正压射孔工艺技术及应用

本文简要地介绍了一种对产层不会造成伤害的新型射孔技术。采用正压射孔技术可使油气井得到相当于增产处理的效果。由于采用这种技术可使油气井产量提高，并易于进行试井分析，所以这种射孔技术有助于对产层的评价。文中还介绍了正压射孔技术近几年的应用实例及效果。

Overblanced Perforating Technology and Its Application

This article briefly decribes a new perforating technique that will result in clean,open perforations. The well is normally stimulated when highly overblanced perforation techniques are used. This perforation process improves formation evaluation because the well flows better and is easy to test. In this article,some of the case histories that have used overblanced perforating technique are also presented.
