| Abstract: | There isn't an obstacle preventing mechanism designed for the existing tube pumps, thereby a new standing valve assembly is designed for preventing obstacles form falling into oil wells. The assembly is mainly comprised of obstacle preventing standing valve, internal tube, external barrel, top and lower connections, and it can solve the problems of tube pump jamming effectively. Use in 3 wells shows that the new standing valve assembly ensured the tube pump operating smoothly by preventing obstacles from falling into wells, and improved the pump efficiency by 4.64%. |
| Keywords: | tube pump standing valve assembly obstacle-preventing field test |
