发明名称 Diversion Plunger for Reciprocating Rod Pump
摘要 A diversion connector is used for a downhole pump having a plunger and a barrel in a well. The diversion connector is useful in a sandy well having particulates. The plunger has an interior and is reciprocated by a rod relative to the barrel. The connector includes one or more bodies, such as a mandrel, attaching the rod to the plunger. The mandrel has a first exterior surface and defines a fluid passage communicating with the interior of the plunger. A sleeve is disposed on the first exterior surface and has an interior surface floating relative to the first exterior surface. The floating sleeve at least partially prevents particulate uphole of the plunger from passing in a gap between the plunger and the barrel.
