Drilling to 5000m with 1500HP ZJ50 rig generates up to several hundred cubic meters of drilled cuttings and low‑gravity solids. Without an engineered ZJ50 rig solids control unit, the mud system quickly degrades:
viscosity & density drift → wellbore instability risk
abrasive particles wear down pumps, pipes, bits → higher maintenance
fine solids overload → centrifuge & shaker screens clog prematurely
A properly sized unit cuts non‑productive time (NPT) and saves USD 500k+ per well in fluid + disposal costs.
| Stage | Equipment | Cut Point | Function |
| 1 | High‑G linear shale shaker (x2) | >74 μm | Remove large cuttings |
| 2 | Vacuum degasser | – | Extract entrained gas (0.03‑0.05 MPa vacuum) |
| 3 | Desander (10″ / 12″ cyclones) | 45–74 μm | Medium‑coarse solids removal |
| 4 | Desilter / Mud cleaner (4″ cones) | 15–44 μm | Fine solids + barite recovery option |
| 5 | Decanter centrifuges | 2–25 μm | Medium‑speed (barite recovery) + High‑speed (ultrafine discharge) |
Total required active volume: ≈ 320 m³ (circulating volume ~65%). TR's modular tank set for ZJ50 offers:
4 to 5 tanks | Effective volume 300 – 430 m³
Compartments sequenced: sand trap → degasser → desander/desilter → centrifuge → suction
Standard auxiliary package:
Agitators (15 kW horizontal, one per compartment)
Mud guns (hydraulic) + jet mixing hopper
55 kW centrifugal sand pump (240 m³/h @30 m head)
Central walkway, stairs, LED lighting, optional insulation shed
All piping external – easy to inspect, clean, replace. No hidden corrosion.
Two medium‑speed decanter centrifuges (TRLW355‑450 series, 1800‑2500 r/min).
→ Returns barite (5 μm+) to active system, reduces fresh barite consumption by ~30%.
One medium‑speed (barite recovery) + one high‑speed centrifuge (TRLW600, up to 5000 r/min).
→ Cuts ultrafines down to 2 μm, ideal for HPHT wells or low‑solids mud.
Recommendation: When drilling fast formations with high fine‑solids generation, add mud cleaner ahead of the centrifuges – extends screen life and lowers centrifuge load.

TR Solids Control successfully commissioned TR50 series solids control unit for ZJ50 land rig in Asia. The system achieved:
Mud recovery rate: 92‑94% (measured over 45‑day drilling campaign)
Solids recovery: >95% of particles above 5 μm
Barite consumption reduced by 28% compared to previous rig without dual centrifuges
On‑site installation took 3.5 days with remote TR support. No unscheduled maintenance stop related to solids control.
In‑house manufacturing of shakers, cyclones, centrifuges, tanks – single source, consistent quality.
Global service footprint – spare parts delivered to ME, SEA, Africa, Europe, Americas within 7‑10 days.
API & ISO – documentation ready for any tender requirement.
Operational advice built‑in – every system includes commissioning checklist + remote tuning for centrifuge speeds.
TR Solids Control does not offer one‑size‑fits‑all. We ask for three inputs:
Rig model variant – ZJ50L / LDB / DB / skid‑mounted
Mud type – water‑based, oil‑based, synthetic, or mixed
Preferred tank layout – compact skid or full‑spread tanks
Then we deliver CAD drawing + equipment list + price within 48 hours.
