Mud motor - Wikipedia
http://primehorizontal.com/drilling-tools/mud-motors/ A mud motor (or drilling motor) is a progressive cavity positive displacement pump (PCPD) placed in the drill string to provide additional power to the bit while drilling. The PCPD pump uses drilling fluid (commonly referred to as drilling mud, or just mud) to create eccentric motion in the power section of the motor … See more Based on the principle developed by Rene Moineau, the theory states that a helical rotor with one or more lobes will rotate eccentrically when the stator contains more lobes than the rotor. The flow of the fluid transmits power … See more The PCPD stator, which is a major component of the pump, is usually lined with an elastomer. Most of PCPD pump failures are due to … See more • Logging while drilling (LWD) • Measurement while drilling (MWD) See more • Mud motor description - Kalsi Engineering See more Normal mud motor construction consists of a top sub, which connects the mud motor to the drill string; the power section, which consists of the rotor and stator; the transmission … See more • Extremely hard rock formations can be drilled with motors using diamond or polycrystalline diamond compact (PDC) bits.
