Embodiment Construction

[0017]The description and examples are presented solely for the purpose of illustrating the different embodiments and should not be construed as a limitation to the scope and applicability. While any compositions or structures may be described herein as comprising certain materials, it should be understood that the composition could optionally comprise two or more different materials. In addition, the composition or structure can also comprise some components other than the ones already cited. Although some of the following discussion emphasizes fracturing, the compositions and methods may be used in any well treatment in which diversion is needed. Examples include fracturing, acidizing, water control, chemical treatments, and wellbore fluid isolation and containment. Embodiments will be described in terms of treatment of vertical wells, but is equally applicable to wells of any well orientation. Embodiments will be described for hydrocarbon production wells, but it is to be underst...

Abstract

A fluid end for use in a high-pressure, reciprocating, fluid pump assembly is provided having a bore therethrough in which a plunger reciprocates. The fluid end is provided with an insert to improve the fluid end washout life. In one embodiment, the insert is constructed of a ceramic material. In another embodiment, the insert includes an abrasive resistant coating or lining.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims benefit of priority to U.S. Provisional Patent Application No. 61 / 394,398, filed Oct. 19, 2010, which is incorporated herein by reference.TECHNICAL FIELD[0002]Embodiments described herein relate generally to abrasive resistant insert, coating or lining for pumps used in high pressure applications. More particularly, but not by way of limitation, an abrasive resistant insert, coating or lining for extending the life of the fluid end of a pump used in the field of oil and gas exploration and production.BACKGROUND[0003]The statements made herein merely provide information related to the present disclosure and may not constitute prior art, and may describe some embodiments illustrating the invention.[0004]The fluid end of a positive displacement or reciprocating pump, such as a triplex pump, is the portion of the pump where a fluid is drawn in via a suction valve. A plunger then compresses the fluid and pushes it...
