GN solids control is experienced in solids
control system for gas and oil drilling. Every year, GN designs and manufactures
many solids control system, for example 4 set solids control system for COSL,
and one set for a European customer. Lately, the European customer visited GN
factory to check the solids control system for gas and oil drilling. This
product is almost finished, and prepared for delivery.
Within this solids control system, you will
find 7 tanks including one small trip tank and small pill tank, and five large tanks: the first
is shale shaker tank in which the first stage and 2nd&3rd stage mud dealing
equipment are mounted and then it's active tank in which the 4th stage mud
dealing devices are installed. And then it's shear tank where mixing hoppers
with shear pump are mounted, and then it's mixing tank where two mixing hopper
and 2 centrifugal pumps are mounted, the 2 pump connected in parallel.
Regarding towards the mud dealing equipment, the very first stage is shale
shaker which separates large solids out, normally over 100 microns the 2nd
& 3rd stage devices are mud cleaner with desander cyclones to get rid of contaminants
over 40 microns out, and desilter cyclones to get rid of contaminants over 20
microns out. Then towards the 4th mud dealing equipment，there are 2 sets
of decanter centrifuge, the first is middle speed that will remove solids form
5 microns to 7 microns out the second centrifuge is high-speed decanter centrifuge that
will separate ultra-fine solids out normally from 2 microns to five
microns. After processed, the mud is
going to be clean enough to become used again. As needed, it will likely be
sheared or included the 3rd and 4th tank.
