Consider the following data for a drillstring composed of only DP and bit (for simplicity's sake, not real world): Drillstring Mud pump DP OD = 5 in Type = Triplex, single acting DP ID = 4.2 in Liner dia. = 7 in DP length = 15,000 ft Stroke length = 14 in Volumetric efficiency =-95% Flow rate = 300 gpm Well Depth (measured) = 15,000 ft Diameter = 8.5 in
U When you are pulling the pipe out of hole and the jets are unplugged, we say the pipe is being pulled dry (only steel goes out). How many strokes are required to fill up the hole after 10 (ten) 90-ft stands have been pulled dry? n When you are pulling the pipe out of hole and the jets are plugged, we say the pipe is being pulled wet (steel + mud go out). How many strokes are required to fill up the hole after 10 (ten) 90-ft stands have been pulled wet?
