HL Petroleum’s ZJ90 drilling rig solids control system was recently put into operation at an oilfield in Kuwait, marking a significant step forward in its application in ultra-deep well drilling.
ZJ90 System Development
1. The Problem
Current ultra-deep well drilling solids control systems suffer from common issues:
-
Unreasonable system layout.
-
Insufficient mud tank capacity.
-
Excessively long pipelines, reducing pump efficiency.
-
Poor mud fluidity.
-
Inadequate weighted mixing systems.
2. The Context & Solution
Drawing on extensive domestic and international experience with 5000-meter and 7000-meter drilling rigs, HL Petroleum conducted in-depth research and comprehensive optimization. This effort led to the design and development of the ZJ90 drilling rig solids control system, addressing these common problems.

ZJ90 System Components
-
Primary Equipment: The system comprises 14 mud tanks and key purification equipment: 5 HDS6216 double-layer mud shale shakers, 1 HCQ270 vacuum degasser, 1 HQJ250×3-100×16 mud cleaner, 1 medium-speed centrifuge, and 1 high-speed variable frequency centrifuge.
-
Auxiliary Systems: Auxiliary systems include a jet mixing operating system, related auxiliary equipment, an explosion-proof electrical control system, and oil and water tanks.
Mud Tank Design and Capacity
-
Tank Design: The mud tanks feature a rounded bottom design. This design helps prevent sand settling, enhances mixing, reduces dead corners, and facilitates sand removal.
-
Volume and Layout: The rounded design also increases the effective volume and simplifies the layout and transport of external pipelines.
-
System Capacity: While featuring a conventional circulation system, the overall system maintains sufficient reserve capacity.
-
Flexibility: This capacity allows the drilling fluid in the tanks to participate in circulation or meet well control requirements at any time.

Engineers designed the entire solids control system in accordance with the drilling rig’s layout and overall design requirements. The design strictly adheres to standard drilling fluid treatment processes and fully meets the special requirements for solids control systems used in 9000-meter ultra-deep well drilling in Kuwait.
HL Petroleum now offers mature solids control systems for ultra-deep well drilling projects over 9000 meters, effectively addressing various challenges. For more information on ultra-deep well drilling solids control system solutions, please feel free to contact us.
