API 7-1 Adjustable Downhole Drilling Mud Motor for Drilling
Product Overview
The downhole motor is a kind of mud-driving down hole drilling tool. The mud from the mud pump goes through the bypass valve and enters the motor. At the gate of the motor it forms pressure difference to rotate the motor’s rotator and to pass the drilling rigs through the cardan and transmission shaft. The performance of the downhole motor is mainly determined by the parameters of the motor.
A positive displacement motor (PDM) is one of the most popular tool for drilling a directional well. It works by boring downwards and pumping mud through the motor itself. As shown in figure 1, the bottom section of the motor has an adjustable bend housing.
Cardan shaft assembly
The function of cardan shaft is to convert planetary motion into
fixed constant rotation of drive shaft, to transmit torque and
speed from motor on the drive shaft, and to the bit.
Resistance High-temperature And Oil Based Mud
The downhole motor is suitable for high-temperature, high oil base
mud system. In the conditions of less than 180°C and high oil,
specially formulated stator elastomer owns high retention rates of
strong force strength, tear strength and other properties. The
oil-resistant elastomer with reasonable magnitude of interference
has better using effect in the high-temperature, high oil base mud.
