Oil production Plunger Inserted Downhole Sucker Rod pump

Plunger Inserted Sucker Rod Pump Description

Sucker-rod pumps are a key component of a sucker-rod lift type with pumping unit system.

Thin wall series rod pump has four groups: RWAC, RWBC, RWAM, RWBM.

There is a wide range of plunger (or pump-bore) sizes standardized by the industry. The API pump-bore sizes that are currently available range from 1 1/16 to 3 3/4 in. in diameter. This 1 1/16-in. size has been added back in the latest edition of the standard. Additionally, a new barrel type has been accepted in the latest API Spec. 11AX. This is the "X-type" barrel. It has a thin-walled barrel configuration for threads on either end of the heavy-walled barrel and is available for metal plungers only. This type of pump does not require the extension couplings normally needed for heavy-walled barrel pumps. Thus, this pump reduces the burst or collapse concerns of the thin-walled extension couplings and allows deeper producing depths to be attained.

Features

1. Plunger in the rod pump
2. Mechanical seating or cup seating, can be available on demand
3. Seating location: top seating; bottom seating

Materials selection

API Spec. 11AX was modified to add not only new sizes and types of pumps with new quality, inspection, and tolerance requirements, but also standardized, widely used pump-component materials. Various material descriptions, their API identification symbol, surface condition, base core hardness, base material, and base-material minimum yield strength for plated barrels, are shown in Table A of Spec. 11AX. Similar tables in Spec. 11AX (B through I) are incorporated for case-hardened barrels, nonhardened barrels, balls and seats, cages, pull tubes, valve rods, fittings, seating cups, spray-metal plungers, and plated plungers. These changes have incorporated the prior information in API RP 11AR^[2] and the NACE International MR 01-76^[3] for materials to be used in most production environments.
