In drilling operation,drilling mud was pumped from the mud tank into standpipe by
high-pressure mud pump. Under the huge pressure, the mud went into the rotary hose
and down through the bottom of the hole. Here mud clean the cuttings and takes them
back to the surface through annulus. At surface, the drill has holding tanks and a collection
of solids-removal equipment for removing the cuttings. Before it returned to the suction pit
it would have passed over a shale shaker to get large cuttings removed,and in later the
connected to choke and kill lines for well control operation.
With the drilling technology development,each performance index has been recognized as
the signs of scientific drilling. Performing a number of functions,drilling mud has been
hailed as the blood of drilling processing. It cleans ans suspends drilling cuttings
concentrated in hole, taking them to the surface where they are settled out,cooling drill bit,
forming mud cake to protect hole well,controlling stratum pressure,diverting pressure
from casing,saving, transmitting hydraulic energy to tools and control corrosion. Solids
control equipment designed for mud purification has been increasingly significant in drilling operation.
