Title
(EN) ARTIFICIAL LIFT MECHANISMS
(FR) MÉCANISMES DE LEVAGE ARTIFICIELS
Abstract
(EN)
The invention relates to electric linear motors and gas springs in reciprocating pumps for oil wells. By the use of this invention a simple, silent, compact and adaptable mechanism can be constructed to drive a wide range of such pumps. The mechanism will sense a variety of pumping conditions and react automatically thereto.
(FR)
L'invention porte sur des moteurs électriques linéaires et des ressorts à gaz dans des pompes alternatives pour puits de pétrole. Grâce à cette invention, un mécanisme simple, silencieux, compact et adaptable peut être construit pour entraîner une large gamme de telles pompes. Le mécanisme détectera une diversité de conditions de pompage et réagira automatiquement à celles-ci.
