摘要： Valve assemblies for reciprocating downhole pumps are provided. The valve assembly may comprise: a flow cage comprising a housing and a tubular insert; an annular valve seat positioned below the tubular insert; and an elongated sealing member positioned above the annular valve seat and at least partially received into the tubular insert. In some embodiments, the elongated sealing member may be more stable and may more securely engage the valve seat compared to spherical valve balls. Related methods are also provided.

摘要： Methods and kits for assembling a flow cage assembly are provided. The flow cage assembly may be used in a traveling valve, a standing valve, or a top plunger adapter of a downhole reciprocating pump. In some embodiments, the method comprises assembling a body, a tubular insert, and a retaining element such that the retaining element forms an interference fit with the body and thereby securely retains the tubular insert within the body. Top plunger adapters are also provided, assembled from embodiments of the methods and kits.

摘要： A standing valve assembly comprises a flow cage, a ball seat, and a valve ball. The flow cage includes a cage body defining an axial fluid passage therethrough, and a bridge extending across the fluid passage. The cage body and the bridge collectively define a plurality of openings to the fluid passage. The valve ball is received between the bridge and the ball seat and is axially movable within the flow cage. The bridge has an upper face and defines at least one guide ramp in the upper face. Each guide ramp extends at a downward angle to a respective one of the plurality of openings.

摘要： The disclosure provides an adaptor apparatus for a downhole artificial lift system. The apparatus includes an upper adaptor section and a base adaptor section. The upper adaptor section includes a top connector portion for connecting to first equipment, and a neck portion below the top connector portion. The base adaptor section includes a bottom connector portion for connecting to second equipment. The base adaptor section and the neck section define a longitudinal fluid passage therethrough. The upper adaptor section includes slots extending from the fluid passage to an outer surface of the neck. The upper adaptor section also includes a plurality of fluid channels recessed in the outer surface of the upper adaptor piece.

摘要： Methods and kits for assembling a flow cage assembly are provided. The flow cage assembly may be used in a traveling valve or a standing valve of a downhole pump. In some embodiments, the kit comprises a tubular body having an axial bore, a tubular insert, and a retaining element. The kit may be assembled such that the retaining element forms an interference fit with the tubular body and thereby retains the tubular insert within the axial bore. In some embodiments, the interference fit between the retaining element and the tubular body may reduce or eliminate a possible failure point within the flow cage assembly.
