TRQJ250×3S-100×20N Mud Cleaner Technical Analysis: Advanced Solids Control Equipment

In oil & gas drilling, horizontal directional drilling (HDD), and mining tailings management, effective solids control of drilling fluids is critical for ensuring operational safety, improving rate of penetration (ROP), and reducing overall drilling costs. As the "precision processing" unit within the solids control system, the mud cleaner plays an essential role in removing harmful solids in the 40-74 micron range.

Xi'an TR Solids Control introduces the TRQJ250×3S-100×20N Mud Cleaner, delivering an efficient integrated solution for challenging drilling fluid conditions through powerful hydrocyclone separation and high-G shale shaker technology.

Product Overview: Integrated Solids Control Solution

The Tianrui TRQJ250×3S-100×20N is an integrated mud cleaner combining desander, desilter, and fine screening functions into a single compact unit. Designed specifically for high-density, high-viscosity drilling fluid applications, this equipment effectively removes harmful solids down to 15 microns and larger through the coordinated operation of hydrocyclone arrays and bottom-flow shale shaker. It efficiently recovers valuable barite weighting material while maintaining optimal mud properties.

Core Technical Parameters

1. Two-Stage Hydrocyclone System: Precision Separation Strategy

   Desander Cyclones(10" × 3 Units)：The unit features three 10-inch hydrocyclones. The large-diameter design ensures exceptional single-unit processing capacity, primarily targeting rapid separation of coarse sand particles in the 45-75 micron range. The parallel configuration of three cyclones delivers high throughput capacity (up to 320 m³/h) while ensuring complete settling of large solid particles.

   Desilter Cyclones(4" × 20 Units)：Downstream, twenty 4-inch small-diameter hydrocyclones are arranged in series. The smaller diameter generates higher centrifugal force fields, enabling efficient separation of fine silt particles in the 15-47 micron range. The circular arrangement of 20 small-cone cyclones maintains ample overflow capacity even at high separation precision, preventing pressure buildup.

2. High-Performance Shale Shaker Unit: Underflow Dewatering and Classification

   The hydrocyclone underflow (concentrated slurry containing residual liquid) directly enters the lower shale shaker for secondary screening—a key feature distinguishing mud cleaners from standard cyclone assemblies. In shaker technology, G-force is the critical indicator of vibration intensity. The TRQJ250×3S-100×20N achieves vibration intensity exceeding 7G, delivering exceptional self-cleaning capability.

   Shaker Model：FLC2003 underflow shaker, typically featuring linear or elliptical motion trajectory for optimal handling of high-concentration hydrocyclone underflow.

   Vibration Intensity：≥7G. High G-force is essential for fine screening applications. This powerful excitation force forces high-density drilling fluid through shaker screens rapidly, preventing screen blinding while ensuring 220-mesh fine screens remain unblocked under heavy loads—achieving effective dry discharge.

   Power Configuration：Two 1.65kW high-performance vibrating motors. Dual motors operating in synchronized reverse rotation generate linear vibration trajectory, ensuring uniform material distribution. The 1.65kW per motor rating provides ample energy reserve for maintaining 7G vibration intensity.

3. Precision Shaker Screens: 220-Mesh Corrugated Screen Configuration

   Screen Size：1050×695mm, with 3 shaker screens in total, delivering large coverage area and high processing efficiency.

   Filtration Rating：220 mesh (cut point ~63μm). This accuracy fills the gap between desilter hydrocyclones (typical cut point around 40μm, varying with operating pressure) and fine-pore shale shakers, effectively reducing barite loss while discharging finer cuttings.

   Structural Features：Single-layer waveform design (waveform layer in composite structures such as PWP/TPP). The waveform support layer increases effective filtration area (open area ratio), enhances tensile strength and erosion resistance, and significantly extends service life in abrasive mud environments.

Technical Advantages & Application Value

1. Maximized Barite Recovery

   Barite is costly in deep well drilling. Through fine separation of 4-inch hydrocyclones and interception of 220-mesh shaker screens, the TRQJ250×3S-100×20N retains most valuable barite in the mud system while discharging useless fine cuttings. Compared to conventional standalone desilters, barite recovery rates improve by 15-20%, delivering direct drilling fluid cost reduction.

2. High Reliability for Complex Working Conditions

   With ≥7G vibration intensity and waveform shaker screens, the unit maintains smooth sand discharge when treating oil-based or water-based mud with high density (above 2.0g/cm³) and high viscosity, eliminating slurry accumulation and overflow commonly seen in conventional low-intensity shakers.

3. Modular Design for Maintenance Efficiency

   TR Solids Control prioritizes on-site maintenance convenience. Hydrocyclone batteries use quick-install clamp connections for easy disassembly and cleaning; shaker screens adopt tension-type replacement, allowing single-person operation in a short time and minimizing downtime.

Recommended Application Scenarios

With strong processing capacity and fine separation accuracy, the TRQJ250×3S-100×20N is especially suitable for:

1. Deep & ultra-deep well drilling: requiring strict control of mud density and solid content.

2. Horizontal & extended-reach wells: needing strict control of low-gravity solids to prevent pipe sticking and excessive torque.

3. Environmentally sensitive areas: offshore drilling platforms and ecologically protected zones, aiming to reduce waste fluid discharge and improve solid waste dryness.

4. Horizontal directional drilling (HDD): efficient bentonite recovery in long-distance crossing projects to reduce mud-making costs.

TR Solids Control TRQJ250×3S-100×20N mud cleaner features an optimized combination of 3 × 10" desander cyclones + 20 × 4" desilter cyclones, supported by ≥7G high-intensity vibration and 220-mesh fine shaker screens, delivering outstanding solid control performance. As a key purification device in the drilling fluid circulation system, it effectively reduces costs, improves efficiency and supports green drilling operations. It is an ideal choice for drilling operations pursuing high efficiency, stability and economic benefits.
