حاسبة هيدروليكا الحفر-Drilling Hydraulics Calculator

Computation of both hydraulic power and impact force substantially depends on calculating pressure drop across the bit. A major chance of normal circulating pressures is lost by pumping through the snoots when spurt bits are used. Then you shall understand Hot to perform Oilfield Drilling Bit Hydraulics computations & download its calculator Excel.


1) the changes in pressure performing from a change in elevation are negligible.
2) the upstream haste(V.) is negligible compared to downstream

illustration On How To Calculate bit pressure drop, Hydraulic Horse Power And Impact Force

Calculate the drill bit pressure drop, hydraulic power and impact force for the following set of conditions

MWT weight = 14.5 Ib/ girl
Flow rate = 300 girl/ min
spurt sizes = three12/32 in. spurts
Result

1. Determine the snoot area, AT
AT = 3 x π/ 4 x( d) 2 = 0.331 in2
2. Eq.3 is used to calculate the pressure drop at the bit
PB = ( 300) 2 x14.5/(0.952 x0.331 2 x 12028) = 1097 psi
3. Calculate the hydraulic power expended at the bit from Eq.4
HHP = ( 1097 psi x 300 girl/ min)/ 1714 = 192 hp
4. The hydraulic impact force due to pressure loss through the drilling bit is reckoned from Eq.5
Fi = 0.01823 x(0.95) x( 300) x((14.5)(,097))(1/2) = 654 Ibيمكنك التحميل من اويل دوت كوت اقوي الكورسات والكتب والبرامج والاخبار الحصريه وفرص العمل الخاصه بمجال البترول oil.com
