3 1/2 Inch Ultra-Short PDM Drilling Motor for Coiled Tubing

Product Introduction

Engineered for restricted wellbore environments, this 3 1/2 Inch Ultra-Short PDM Drilling Motor measures a highly compact 2.00 meters in overall length. The heavy-duty metallic housing features a smooth, corrosion-resistant finish designed to withstand severe downhole friction. Fitted with standard 2 3/8 PAC upper and lower connecting threads, it ensures rapid and secure integration with various coiled tubing (CT) bottom hole assemblies (BHA) and measurement-while-drilling systems, facilitating a seamless mechanical connection before deployment.

As drilling fluid pumps through the tool, operators can monitor distinct, predictable differential pressure feedback at the surface. This clear pressure dynamic allows for real-time weight-on-bit (WOB) optimization, preventing stalls and maintaining a steady mechanical penetration rate. The motor transforms hydraulic energy into a consistent, low-vibration rotational force, emitting a deep, steady hum indicative of its balanced internal mechanics. This minimized overall length delivers outstanding flexibility, greatly maximizing reach and milling efficiency in tight, highly deviated casings.

Product Uses

Application Scenarios of Xinyongjia C9LZ89X7.0-2 Straight PDM Motor for Coiled Tubing

1. Plug & Cement Plug Milling for CT Workover

   Generating a reliable and steady rotational force, this slim PDM mud motor effectively mills out composite bridge plugs and hardened cement barriers within narrow casing strings. The consistent torque output prevents bit jamming, clearing wellbore obstructions swiftly to restore production flow after complex fracturing operations.

2. Slim-Hole Re-entry & Sidetrack Drilling

   The compact, small-diameter straight motor easily passes through restricted production tubing to execute re-entry and sidetracking tasks in mature oil assets. By enabling precise directional drilling without the need for a full-scale rig mobilization, it allows operators to tap into bypassed hydrocarbon reserves while significantly reducing overall site expenditure.

3. Wellbore Cleanout & Paraffin Removal

   Functioning as a dependable downhole power unit, this tool excels in routine maintenance tasks such as sand washing, scale eradication, and heavy wax removal. Its agile design maneuvers through highly deviated and horizontal sections, ensuring thorough cleanouts that restore the optimal inner diameter of the wellbore.
