حداکثر سرعت حفاری

محاسبه حداکثر سرعت حفاری بر حسب فوت بر ساعت

General Formula:

Maximum Drilling Rate feet/hour = 67 * (mud weight out IN ppg — mud weight OUT ppg) * (circulation rate in gpm / Diameter of your hole²)

Example:

Mud Weight Out, 9.6 ppg

Mud weight in, 8.8 ppg

Circulation Rate, 544 gpm

Hole size, 17 5/8 inch

To solve:

 1 : Maximum Drilling Rate in ft/hr = 67 * (9.6 — 8.8) * 544 / 17.6252 2 : Maximum Drilling Rate in ft/hr = 67 * 0.8 * 544 / 310.64
3 : Maximum Drilling Rate in ft/hr = 93.87
