2″～ 5″ 21～70MPa Drilling Fluid Manifold Process specification
language (PSL) : PSL1～PSL4
Introduction
Drilling Fluid Manifold
Series of drilling fluid manifolds are designed and manufactured as
per china’s oil and gas industry standards SY/T 5244－2006.The
drilling fluid manifold is one of the main devices used in high
pressure jet drilling, which can introduce the high-pressure mud
from mud pumps into borehole to scavenge the bottom hole, carry out
cuttings and cooperate with well cementing and other operations.
Structural Features
· The drilling fluid manifold is mainly composed of the surface
pipeline, the surface valve group, the crossover tee, the standpipe
line, the standpipe valve group, the gooseneck, the rotary hose,
and the pressure gauge.
· Pipelines are connected by high-pressure bispherical unions and
the material adopts quenched and tempered high strength alloy
steel. The whole structure of manifolds can realize fast handling
and seal parts selects rubber o-rings. Each of pipe fittings and
part elements in manifolds are subject to the strength test to
ensure performance requirements.
Structural Features of whole Set Manifold
· The whole manifolds from the mud pump to the rotary hose includes
four big parts: the surface valve group, the surface pipeline, the
drill floor valve group and the standpipe line on the .
·Each of part elements in the whole set manifold is connected by
spherical unions, with great interchangeability, quick removal and
installation, and permission to tilt ±8° in use.
· The surface pipeline and the standpipe line can be divided into
several sections allowing the user to choose freely in use
according to the actual situation at the well site.
