Circulation System: Comando General Del Ejército Escuela Militar de Inginieria "Mcal. Antonio Jose de Sucre" Bolivia

The document discusses the circulation system used in drilling operations. It describes the surface equipment which includes pumps, mud dams, stand pipes, swivels, solids control equipment, degassers, and blowout preventers. It also describes the downhole equipment which includes drill pipes, drill collars, tools, bits, and the wellbore. It provides more detail on how the mud circulation system works, including the mud pump drawing mud from pits and pumping it through lines, hoses, drill strings, up the annulus, over shale shakers to separate cuttings before recycling the mud back downhole.

Circulation system

The main function of the circulation system is to extract the rock cuttings from the well during
the drilling process. The system is composed of surface and sub equipment surface as
shown in the following figure:

The surface equipment is composed of:

 The pumps
 The mud dams (discharge, from settlement and suction)
 The stand Pipe, swivel and arrow
 The solids control equipment
 The degasser
 Temblor in
 Preventers
The sub surface equipment is composed of:

 Drilling pipe
 Lastrabarrenas
 Tools
 Barrena
 The well itself
Circulating Equipment.
Mud circulates through many pieces of equipment, including the mud pump, the discharge line, the
standpipe, the rotary hose, the swivel, the kelly (or the top drive), the drill pipe, the drill collars, the
drill bit, the annulus, the return ine. the shale shaker, the desilter, the desander, the mud pits, and
the suction line

The mud pump


The mud pump draws in mud through a suction line from the mud pits, or tanks, and sends it out a
From the discharge line, the mud goes into the standpipe. The discharge line. vertically up one leg of
the derrick. Mud exits standpipe the standpipe into a strong, flexible, and reinforced rubber hose
called the rotary hose, or kelly hose. The rotary hose joins the swivel at the gooseneck (fig. 103). The
mud then flows down the kelly (or through the top drive), drill pipe, and drill collars. It jets out of the
bit nozzles and moves cuttings away runs from the bit. The mud and cuttings then head up the hole
in the annulus. The annulus, or annular space, is the area be- tween the drill string and the wall of
the hole. The mud leaves the annulus through a steel pipe called the mud return line. It falls over a
vibrating screen, the shale shaker ng. 104). The shaker screens out the larger cuttings and, in some
cases, dumps them into the reserve pit. Offshore and in environmentally sensitive areas, however,
the shaker dumps the Cuttngs into a receptacle. Later, the contractor removes the receptacle,
washes the cuttings if required, and properly poses of them. In either case, the clean mud drains
back into the mud tanks. The pump then recycles it back down the hole.
