ESTIMATION OF VIBRATION SCREENS NETS SPECIFIC THROUGH CAPACITY Russian patent published in 2010 - IPC B07B1/40 E21B21/06 

FIELD: oil-ang gas production.

SUBSTANCE: vibration screen nets specific though capacity estimation method according to boring solution, characterised with that vibration screen installs into measurement cell as a truncated cone with the net sample on its smaller base, measure the boring solution density, start the vibration screen, supply the boring solution defined volume into measurement cell, continuously measure screened solution mass and define the mass derivative vs time. After the screening process ends measure boring solution layer height on the net with formula where m(t) - solution screened mass current amount, kg; m_k - solution mass after screening, kg; ρ - boring solution density, d - cones smaller base diametre, m; α - measurement cell cone angle, define net's instant through capacity with formula q(t)=1/S·ρ·dm(t)/dt, where S - net sample area, m²; and define screen net specific though capacity dependently on the boring solution layer on the net.

EFFECT: efficiency increase in boring solution refinery.
