HDD Mud Recycling System

HDD Mud Recycling System

HDD (Horizontal Directional Drilling) mud recycling system is specialized solids control solution designed to clean and reuse drilling fluid during trenchless pipeline installation. It processes returned mud from underground, removes drilled solids, and returns cleaned mud to the drilling system.

The system integrates a suite of equipment, including shale shakers, desanders and desilters to effectively separate drilling wastes of different particle sizes. It also features a jet mixing unit is incorporated for adding and blending drilling fluid additives, with circulation maintained through a mixing hopper to ensure homogeneous slurry preparation that meets performance requirements for reuse. The processed mud is then conveyed back to the horizontal directional drilling rig by mud pumps, enabling continuous circulation.

Working Principle of Mud Recovery System

HDD mud recycling systems operate on the core principle of progressive solid-liquid separation + mud performance reconditioning, enabling continuous reuse of drilling fluid. The system removing solids from coarse to fine via physical separation (vibration, centrifugal force, gravity) while restoring mud's rheological properties (viscosity, lubricity, stability) for repeated circulation.

The system follows closed-loop cycle: Mud Preparation → Circulation & Cuttings Transport → Multi-Stage Separation → Mud Reconditioning → Re-Circulation. 

TR Mud Recycling System is customized according to the HDD rig tons and Mud pump flow. the system capacity such as 200GPM, 500GPM, 1000GPM.

Typical Parameters Of HDD Mud System

Advantages of HDD Mud Recycling System

1. Designed based on TR's over 10 years of technical experience in the solids control industry and extensive market research, this mud recycling system features a rational structure, efficient processing capabilities, and a wide range of applications.

2. Integrated design supports mud cleaning, recycling and reuse, as well as mud mixing and storage. It reduces the overall dimensions of the tank system, meeting the site and space constraints typical of horizontal directional drilling (HDD) operations.

3. The electrical system is explosion-proof, dust-proof, and rain-proof, ensuring operational reliability and quality.

4. The tank structure is simple, compact, and lightweight; walkways and guardrails are foldable or detachable, facilitating easy transport and installation.

5. TR Solids Control holds API and ISO certifications, as well as ISO 14001 (environmental management) and ISO 18001 (occupational health and safety) certifications, enabling the system to meet export standards for markets worldwide.

Xi'an TR Solids Control is a manufacturer of solid-liquid separation equipment holding API certification. In addition to HDD mud recycling systems, the company produces a wide range of other mud recycling and purification systems, including those for oil and gas drilling, piling, metro shield tunneling, river dredging, and coalbed methane drilling, all of which have been successfully deployed in numerous field operations.
