The drilling motors we offer can be divided into 18 different series, including 1-3/4", 2- 3/8", 2-7/8", 3-1/2", 3-3/4", 4-3/4", 5-1/8", 5-1/2", 5-3/4", 6-1/2"., 6-3/4", 7', 7-1/4", 7-3/4", 8', 8-1/2", 9-5/8", 11-1/4", and each series has three categories, which are vertical motor, single bent angle motor, double bent angle motor. DY-drill motors are available for the drilling in vertical wells, directional wells, cluster wells and horizontal wells. Especially, the motors featured with minor outside diameter represented by 2-7/8" with a 5/6 rotor/stator, 3-1/2" with a 7/8 rotor/stator, 3-3/4" with a 7/8 rotor/stator, and 4-3/4"with a 7/8 rotor/stator can be used for the drilling applications in both casing window sidetracking and workover operations.
