Problems solved by technology
The valve ball of the pump with this structure is suspended on the upper part of the ball seat with shear nails and shear rods to form a steam injection channel, and the structure is complex
The other is to inject gas through the outside of the pump barrel. The steam in this structure cannot be injected to the bottom of the well, which greatly reduces the effect of gas injection.

Description
technical field [0001] The invention relates to the technical field of pumping units, in particular to a pumping unit system with multi-stage steam injection seals. Background technique [0002] In recent years, as the world's energy problems have become increasingly prominent, energy conservation of pumping units has become a major concern of people. Various domestic manufacturers and research institutes continue to apply new technologies, through structural optimization design and improved balance methods, etc., to achieve pumping units. The purpose of energy saving of oil pumps is to reduce energy consumption and reduce oil production costs. A batch of new pumping units have been put into oil field production in the past few years. How to ensure high pumping efficiency, long life of pumping units, small dynamic load, and Quantity stability is also a problem that pumping units are currently facing. [0003] As a key component of the downhole pumping unit system, the packe...
