The rationality of drilling fluid centrifuge separate not aggravate drilling fluid

In order provide stabilize well hole and the maximal mechanical drilling speed, many workers are confined to 5% of the drilling cutting’s volume, so the solid particles in every barrel will be prepared 19 barrel drilling fluid, under 7% drilling cuttings concentration, every barrels solid phase should be added 13.3 barrel diluents. 

Know the component and cost of every barrel and capacity drilling fluid, we can easy to calculate the cost benefit of eliminate drilling cuttings. If the cost of compound drilling fluid is 10 dollars and 5 dollars every barrel, accordingly, the total cost of every barrel is 15 dollars. If the drilling cuttings’ volume is controlled in 5% by us, eliminate every solid particles will be decrease 285 dollars. Using the numerical value, it is easy to confirm use centrifuge whether has effective. So to not aggravate drilling fluid, the use of many centrifuges is correctly.

 

The rationality of drilling fluid centrifuge separate the aggravate drilling fluid

If suppose is relate with the maximum acceptable concentration, the same method can calculate the economic benefit which eliminate the solid particles in aggravate drilling fluid. If we suppose that the maximum concentration is 5% in oil base drilling fluid, we can permissible 8% in oil base drilling fluid or combining base drilling fluid, like that, we cancel 19 water base drilling fluid of barrels diluents and 11.5 barrels oil base and combining bas drilling fluid. Know the cost of every barrel new drilling fluid, we can calculate the economic benefit of eliminating the solid particles, it is easy to confirm using centrifuge is whether economy.
