Downhole motor for directional drilling

Tiptop is specialized in designing & manufacturing mud motor, motor manufacturing, testing and maintenance equipment. The stable quality and high performance of our mud motors, spare parts and equipment have been effectively proven by customers in Russia, India, Iran and China.

Positive-Displacement Motors (PDM) make use of a power generation section which is made up of a rotor/stator combination. In order to move a rotor part, a PDM requires hydraulic power from drilling fluid flowing through the power generation part. With a PDM, the stator and rotor work in tandem in the same way that gears do. The stator acts as the outer gear, and is made from a moulded elastomer featuring at least two lobes. The OD of the elastomer is protected by a secure metal casing. The rotor is positioned within the stator, and acts as an internal gear. This rotor is made of metal, and will have one less gear or lobe than the stator. Because of this difference, a cavity is created which is filled with drilling fluid when the PDM is downhole. This cavity acts as a wedge when it is put under pressure, and because the drilling fluid itself can’t be compressed, the force applied to the top of the wedge causes the rotor to move.

Tiptop downhole motor can work around 200 hours for one running in general and working life of the power section has reached more than 1,000 hours. Our company is able to provide all sizes and configurations of the downhole motor. We provide specific design products according to the customer's requirements for the torque, displacement, well temperature and other parameters.

•Size Range: Available from 1-11/16”OD to 11-1/4”OD
•Types: Adjustable bend housing type, Water based mud type (conventional type), Oil-based mud type, Salty based mud type
•Structure: Consists of Bearing section assembly, Universal coupling assembly, Power section assembly, Anti-drop device assembly and By-pass valve assembly or Crossover sub.

•Advantages
•With the diversity and flexibility to work in all drilling environments.
•Utilization of high quality materials, including forged steel drive shafts (laser welding alloy on drive shaft surface), which reduces wear and tear and down-time for servicing.
•With safety anti-drop device which reduces the probability of residual motor parts left in the drill string in the event of connection failure.
•High quality power section designs which efficiently maximize the amount of speed and torque being transmitted to the drill bit.
•Tungsten carbide radial bearings which significantly reducing wear and improves durability and consistency in performance.

Note: We have the capacity to design and customize spare parts according to your requirements/drawings.
