The invention relates to a technological method for a
drilling fluid solid control circulation
system, in particular to a technological method for the treatment of
drilling fluid produced during oil and gas drilling. The technological method for the
drilling fluid solid control circulation
system adopts the following device components: a special concentration treatment device I, a special centrifugal
machine, an
oil field mud pump I, a special
cyclone set I, a special concentration treatment device II, an
oil field mud pump II, a special
cyclone set II, a special concentration treatment device III, an
oil field mud pump III, a storage box, an oil field mud pump IV, a special
filter press (or a special stacked spirals), a
solid-phase mud cake collection
barrel (or a mud transfer tank), and a circulating fluid
storage tank. The technological method for the drilling fluid solid control circulation
system has the following benefits: desanding, mud removal, destabilization and gel breaking in a circulating and classification manner are achieved through the two-stage special
cyclone sets, so that the classifying effect is remarkable; circulating concentration is achieved through the three-stage special concentration treatment devices, so that the
concentration effect is remarkable; the treated drilling fluid is recycled; treated solid-phase mud cakes or highly-concentrated mud are / is directly transported away.
