Import Api Drilling Mud Motor — Buy in wholesale FOB from Supplier in China

The API Drilling Mud Motor is a positive displacement downhole motor that converts hydraulic energy from drilling fluid flow into mechanical torque and rotation at the bit. Its architecture follows the standard downhole motor layout: crossover sub, safety catch sub, power section with helical rotor and stator, coupling assembly, and bearing assembly with thrust and radial bearing packages. The motor increases rate of penetration in hard or abrasive formations, improves directional and horizontal wellbore trajectory control, and reduces mechanical wear on surface rotary equipment including the swivel, Kelly, and rotary table drives. Energy consumption at surface is lower than conventional rotary drilling since torque generation occurs at the bit rather than transmitted through the entire drill string.

The power section typically uses a multi-lobe Moineau-type positive displacement pump principle with an elastomeric stator bonded to a steel housing and a chrome-plated or nitrided alloy steel rotor. Common lobe configurations range from 4:5 to 7:8 rotor-stator lobe ratios depending on torque and speed requirements, though the exact configuration for this unit is not stated. Bearing assemblies may be mud-lubricated or sealed bearing designs with tungsten carbide or diamond-impregnated thrust bearings to handle dynamic and static axial loads. Typical operating parameters include differential pressure across the power section of 6.9 to 10.3 MPa (1000 to 1500 psi), bit speed ranges of 100 to 300 rpm, and output torque proportional to pressure drop, though buyers must confirm exact performance curves with the supplier.

Directional drilling contractors and national oil companies deploy mud motors in steerable assemblies with MWD tools and adjustable bent housings for build-and-hold or drop-off sections. The motor is suited for both conventional and unconventional reservoir development where precise wellbore placement is critical. Buyers should request the full performance specification including power section lobe ratio, maximum differential pressure, torque-speed curve, flow rate range, and bit speed output. Verification of bearing type, expected run life in hours for the intended formation abrasiveness, and rebuild versus non-rebuild design philosophy should also be discussed with Dongying Lake Petroleum Technology Company before procurement.

Dongying Lake Petroleum Technology Company is located on Huanghe Road, Dongying, Shandong Province, postal code 257000, with a listed address region noted as 'Not Selected' in the source. The company holds a Harbor trust tier with a 0.00% response rate and zero recorded average response hours, indicating no active platform messaging engagement. Buyers should treat this as a signal to pursue direct outreach through the physical address, telephone, or other established channels rather than relying on platform-mediated communication.

The supplier's listing emphasises functional advantages and standard motor architecture without providing company history, manufacturing scale, certification scope, or client references. No information is given about years in business, production capacity, engineering staff, or aftermarket service capability. The Huanghe Road address places it within Dongying's oilfield equipment manufacturing base. Buyers should independently verify business registration, API license status for downhole motors, and whether the company manufactures power sections in-house or sources from third parties.
