Abstract
Since the invention of screw pump in 1930, screw pump technology has been continuously improved and perfected, especially the development of synthetic rubber technology and bonding technology, which has made screw pump widely used in oil exploitation. Screw pump wells have the characteristics of low investment, high pump efficiency and energy saving. At present, screw pump has become a common artificial lifting method in oil fields using polymer flooding. In view of the present situation that screw pump wells are used for oil production more and more in Liuchang area, this paper discusses how to improve the production efficiency of screw pump wells in field production to promote the development of oil fields.
