DRILL STRING DESIGN

The controlling criteria for drill string design are collapse, tension, slip crushing, and dogleg severity. Collapse and tension are used to select pipe weights, grades, and couplings. Mud Density was measured in units "metric" or "english"

COLLAPSE The most severe collapse loading occurs when the evacuated (or partially empty) drill string reaches the bottom of the well. The load from the annular mud tends to cause pipe collapse. String Length ft m #VALUE!

MUD PUMP REQUIRED CAPACITY CALCULATIONS The calculatios of required capacity of the mud pump are based on selected API Rules of Thumb Guide for Hydraulics as: Flow Rate, m 3 /min Bit Pressure Loss Annular Velocities

= 5 x Bit Diameter, m = 50-65% of Pump Pressure = 35-40 m/min for mud 45-55 m/min for water

To reach recommended Annular Velocity of drilling mud the minimum Flow Rate must be maintain as shown in the table below: Hole Size inch mm

Drill Pipe OD inch mm

Annular Area 2 2 in m

Velocity, m/min

Min. Pump Rate 3 m /min GPM

Required Pressure Rating of the Mud Pump is calculated from expected pressure losses in the well as shown in the table below: Circulating Losses Calculations Pump Rate, m3/min

Remark: The Bit Pressure Loss is not included in calculations above. Approximate value of bit loss based on experience is taken of 50% of pump pressure. Bit Pressure Loss is included in final result below.

Result: To perform sufficient cleaning of the bottom of the hole and efficient penetration rate while drilling, the Mud Pump(s) should has minimum required ratings as: Working Pressure (including Bit Pressure Loss) at least of
