Custom Export High-Temperature 1 11/16 inch Drilling Mud Motor for Coiled Tubing Operations

Product Introduction

This specialized 1 11/16 inch high-temperature resistant mud motor is engineered specifically for complex coiled tubing operations. Constructed from high-strength, corrosion-resistant alloy materials, the tool body maintains exceptional structural integrity even when exposed to harsh downhole environments rich in hydrogen sulfide (H2S) and carbon dioxide (CO2). Featuring a precision-machined tungsten carbide rotor and standard 1 AMMT threads at both the drill pipe and bit ends, this slim-profile positive displacement motor (PDM) generates consistent, stable torque. It is widely compatible with various drilling fluids, including water-based mud, oil-based mud, and nitrogen (N2) systems, making it highly adaptable for diverse well-intervention tasks. Operators rely on this compact coiled tubing bottom hole assembly (BHA) to execute slim-hole milling, sidetracking, and cleanout procedures with maximum efficiency. It strictly complies with global technical standards, ensuring reliable performance for overseas coiled tubing well service projects requiring durable and resilient downhole equipment.

Technical Parameters

Product Uses

1. Plug & Cement Plug Milling for CT Workover

   This slim coiled tubing PDM mud motor delivers steady, aggressive torque to mill through composite bridge plugs and solid cement plugs inside restricted casings. The optimized power output prevents bit stalling, ensuring a continuous cutting action. As a highly compact screw drilling tool, it clears hard obstructions efficiently, producing fine cuttings that are easily circulated out of the wellbore, thereby accelerating post-fracturing well restoration and preparing the zone for immediate production. Field engineers rely on its predictable power curve to maintain optimal milling speeds without overloading the coiled tubing string. The resulting operational fluidity minimizes mechanical fatigue and ensures the wellbore is fully restored to its maximum flow diameter.

2. Slim-Hole Re-entry & Sidetrack Drilling

   The small-diameter, straight downhole mud motor perfectly fits narrow tubing strings for precise re-entry and sidetracking applications in mature, depleted oil wells. By delivering high mechanical drilling speed (ROP) and preserving the fatigue life of the continuous tubing, this drilling tool taps into bypassed hydrocarbon reserves without the need for expensive rig mobilization. The smooth operational acoustics and minimal surface vibration confirm its efficient downhole engagement, drastically cutting overall operation costs while maximizing the economic recovery of aging assets. Its precise directional control allows operators to navigate complex casing windows with confidence. The motor's consistent torque output ensures the milling bit maintains a steady trajectory, reducing the likelihood of doglegs and ensuring a clean, viable sidetrack for subsequent completion strings.

3. Wellbore Cleanout & Paraffin Removal

   Our versatile CT screw drilling tool expertly handles complex sand washing, hard scale crushing, and thick wax removal in highly deviated and horizontal slim wells. Compatible with various fluid mediums, it serves as reliable downhole power equipment for regular coiled tubing maintenance. The durable internal components resist the abrasive nature of sand-laden returns, ensuring the motor continues to unblock production pathways and restore optimal flow rates without premature wear. During cleanout operations, the motor's ability to maintain rotation even at lower flow rates prevents solids from settling and packing off the annulus. This continuous agitation is crucial for sweeping heavy debris to the surface, leaving the wellbore exceptionally clean and ready for enhanced production phases.
