Abstract
A rod pump system includes subsystems or components which are adapted to provide efficient operation when operating with produced fluids having high gas content or in highly deviated wellbores, or both. The subsystems or components include a traveling valve assembly, a sliding top valve assembly, an oil/gas separator, or a rod bushing and pump barrel assembly, or combinations of such subsystems or components. The rod pump system may be deployed in conjunction with conventional, unconventional or enhanced oil recovery techniques, such as steam-assisted gravity drainage, miscible flood, steam, gas or water injection.
Claims14
A rod pump system comprising a traveling valve having a pump barrel and comprising:
- (a) a reciprocating plunger which engages a cylindrical valve housing having an interior valve seat with a central opening and a stem guide bushing, the valve seat and stem guide bushing defining a cavity therebetween;
- (b) a valve comprising a valve body having a face which mates with the valve seat, a valve stem which extends upwards, and a tapping stem which extends downwards through the central opening, wherein the valve body is axially moveable within the cavity;
- (c) a tapping guide comprising a tubular member slidingly disposed on the valve stem and a transverse disk having an upper surface and a lower surface, and defining flow openings, wherein the tubular member extends above and below the disk;
- (d) a first biasing means acting between the stem guide bushing and the tapping guide transverse disk upper surface to resist upward movement of the tapping guide relative to the valve housing;
- and
- (e) a second biasing means acting between the lower surface of the tapping guide disk and the valve body to resist upward movement of the valve body relative to the tapping guide.
