~~ 890 Drilling and Well Completions Table 4-1 15 gives the performance characteristics for various circulation flowrates for the 5:6 lobe profile, 6 $-in. outside diameter positive displacement motor. Figure 4-205 shows the performance of the 5:6 lobe profile positive displacement motor at a circulation flow rate of 400 gal/min. The positive displacement motor whose performance characteristics are given in Table 4-114 is a 1:2 lobe profile motor. This lobe profile design is usually used for deviation control operations. The 1:2 lobe profile design yields a downhole motor with high rotary speeds and low torque. Such a combination is very desirable for the directional driller. The low torque minimizes the compensation that must be made in course planning which must be made for the reaction torque in the lower part of the drill string. This reactive torque when severe can create difficulties in deviation control planning. The tradeoff is, however, that higher speed reduces the bit life, especially roller rock bit life. The positive displacement motor whose performance characteristics are given in Table 4-115 is a 5:6 lobe profile motor. This lobe profile design is usually used for straight hole drilling with roller rock bits, or for deviation control operations where high torque polycrystalline diamond compact bit or diamond bits are used for deviation control operations. Example 3 A 6+-in. outside diameter positive displacement motor of a 1:2 lobe profile design (where performance data are given in Table 4-114) has rotor eccentricity of 0.60 in., a reference diameter (rotor shaft diameter) of 2.48 in. and a rotor pitch of 38.0 in. If the pressure drop across the motor is determined to be 500 psi at a circulation flowrate of 350 gal/min with 12.0 lb/gal, find the torque, rotational speed and the horsepower of the motor. Torque. Equation 4-160 gives the fluid cross-sectional area of the motor, which is A = 2(0.6)(2.48) = 2.98 in.* Equation 4-159 gives the specific displacement of the motor, which is Table 4-115 Positive Displacement Motor, 6%-in.

(Courtesy Smith International, Inc.) s = (1)(2)(38.0)(2.98) = 226.5 The torque is obtained from Equation 4-162, assuming an efficiency of 0.80 for the 1:2 lobe profile motor. This is M = 0.0 133( 226.5)( 500)( 0.80) = 1205 ft-lb Speed. The rotation speed is obtained from Equation 4-163. This is N= 231.016(350) 226.5 = 357 rpm
