Definitions

  • the present invention generally relates to hydraulic fracturing pump systems and, more particularly, to the fluid ends of multiplex reciprocating fracturing pumps.
  • Multiplex reciprocating pumps are generally used to pump high pressure fracturing fluids into wells for recovery of oil and gas trapped in shale formations and the like.
  • these pumps have two sections, a power end which is coupled to a diesel engine and transmission that drives the pump and plungers in the fluid ends in which a mix of water, sand and chemicals are pressurized up to 15,000 psi or more.
  • multiplex reciprocating pumps are commonly in the form of triplex pumps having three fluid cylinders and quintuplex pumps that have five cylinders. It will be appreciated, however, that the present disclosure has application to pumps which can utilize the features thereof in forms other than the triplex and quintuplex pumps.
  • the fluid ends of these pumps typically comprise a single block having cylinders bored therein and are commonly referred to as monoblock fluid ends or an assembly of individual bodies with cylinders, referred to as modular fluid ends.
  • the pumping cycle of a fluid end is composed of two stages, a suction cycle during which a piston moves outward in a bore, thereby lowering the fluid pressure in the inlet to a fluid end and a discharge cycle during which the plunger moves forward in the plunger bore, thereby progressively increasing the fluid pressure to a predetermined level for discharge through a discharge pipe to a well site.
  • Fluid ends used in well site applications for oil and gas exploration have limited service life due to fatigue crack failures. These failures are a result of operating pressures, mechanical stresses, erosion and corrosion of the internal passages which have been addressed in prior art efforts with limited success.
  • U.S. Pat. No. 3,786,729 is directed to a liner seal for the plunger bore and does not address the protection of high stress areas such as those associated with intersecting bores.
  • This disclosure is generally directed to a system for substantially protecting the portions of the fluid end body flow passages from impingement by high pressure fracking fluid passing therethrough to provide enhanced erosion and corrosion resistance as well as improved fatigue properties and extended service life.
  • a first aspect of this disclosure is directed to sleeve and cartridge components which cooperate to protect fluid end body portions surrounding the outer surface thereof from direct impingement thereon by high pressure fracking fluid passing through said fluid end.
  • a second aspect of this disclosure is directed to a sleeve that is received in a plunger bore of a fluid end body which sleeve includes a pair of apertures that are connected to, and in flow communication with, the outlet of the suction bore and the inlet of in the discharge bore.
  • a kit which includes one or two sleeves, a cartridge, and a plug is provided for installation in a conventional fluid end steel body which, when installed therein, cooperate to protect the fluid end body portions surrounding the outer surfaces thereof from impingement by high pressure fracking fluid passing through said fluid end.
  • a further aspect of the present invention is directed to a method of installing one or more components in the flow passages of a fluid end body of a reciprocating pump used in the recovery of oil and gas for the purpose of extending the service life thereof and to minimize the effects of erosion, corrosion and fatigue, such components being configured and located within one or more bores in said fluid end body to protect the portions of said fluid body surrounding those components including portions associated with high stress areas such as the corners of intersecting bores.
