| 摘要 |
The present invention refers to a device for the controlled repressuring of intermittent oil wells including a mechanical pumping rig and mechanical pumping units with a vertical reciprocating-motion rig, useful in wells that present an extraction with a low percentage of useful product due to the presence of congenital water or gas. The purpose of the present invention is to improve the production in intermittent oil wells by controlling and reducing the percentage of congenital water, thus turning pumping in gas wells into a more effective process, and avoiding the problems related to the handle of said elements.
