Granule, desilter can only remove the solid phase particles of 44 μm of ＞.After drilling fluid is through vibrosieve, desander and desilter purified treatment,
Still containing the harmful solid phase particles within substantial amounts of 44 μm in mud.The presence of these harmful solid phase particles to drillng operation very
Harmful, there is the serious mill for mutually grinding that the density and viscosity that increased drilling fluid can also cause machinery in drilling process
Damage.
Mud solid phase processes desander used and desilter is all made up of multiple cone cyclones at present, and drilling fluid is passed through
Rotation produces effluxvelocity to sand pump impeller at a high speed, produces centrifugal force harmful solid phase is separated in cone cyclone.And remove
In sand device and desilter cone cyclone, the size of effluxvelocity is again by pump discharge size, drilling fluid viscosity, drilling fluid density
Affect, if drilling fluid viscosity is high, density big, the efficiency of pump is low, effluxvelocity and flow do not reach cyclone inlet flow and want
Ask, desanding, desilt effect and be affected, cause to be harmful to solid phase being in a large number trapped in drilling fluid, very big harm is caused to drilling well.
Drilling fluid viscosity ＞ 58 seconds especially in deep drilling operation, density is 1.6g/cm3When, desander and desilter cone eddy flow
The centrifugal force field of device does not build up, a large amount of presence of the harmful solid phase particles of drilling fluid, and only first-stage centrifugal machine purifies solid phase on the lower
Just extremely difficult, so often resulting in centrifuge card machine locking, aggravate equipment attrition and damage and by forced-stopping machine, reduce brill
Well speed, acceleration equipment are worn and torn, and increase drilling cost, affect drilling efficiency.
