Drilling Mud Cooler

High mud return temperatures are common in deep wells, high-temperature wells, directional drilling, and geothermal operations. Excessive mud temperature can affect downhole instruments, drilling tools, seals, and other equipment, while also making temperature control more difficult during continuous circulation.

TR Drilling Mud Cooler is designed to remove heat from circulating drilling mud and bring the fluid back into a suitable operating temperature range. The system provides rapid mud cooling and continuous temperature control, with a temperature reduction of 20–30°C under suitable operating conditions.

Key Features

1. Rapid mud cooling: quickly removes heat from circulating drilling mud.

2. 20–30°C temperature reduction: provides the specified cooling performance under suitable operating conditions.

3. Closed-tube indirect cooling: mud flows through a sealed copper tube bundle while spray water and forced airflow remove heat outside the tubes.

4. PLC-based temperature control: inlet and outlet temperature sensors provide real-time feedback for automatic cooling adjustment.

5. Oil- and corrosion-resistant materials: selected for drilling-fluid service.

6. Local or remote control: available for different field control arrangements.

Working Principle of Mud Cooling

Hot drilling mud enters the cooling system and flows through a sealed copper tube bundle inside the cooling tower. The mud remains inside the tubes and does not come into direct contact with the cooling water or air.

Cooling water is sprayed over the outside of the tubes while the axial-flow fan draws air through the tower. Heat passes through the tube walls and is removed by the spray water and airflow. The cooled mud leaves through the bottom outlet and returns to the mud system.

Inlet and outlet temperature sensors send temperature readings to the PLC. The PLC adjusts the cooling operation during circulation to maintain the required mud temperature.

Applications

TR Mud Cooling Systems are used for drilling operations with elevated mud return temperatures, including:

• Deep and high-temperature drilling

• Directional drilling

• Geothermal drilling

• Other high-temperature drilling operations

Selection Guide

Mud cooler sizing is based mainly on mud flow rate, inlet temperature, target outlet temperature, ambient conditions, cooling-water conditions, and mud properties.

The standard TRLQ120 and TRLQ200 models handle 120 and 200 m³/h respectively. TR can size the cooling capacity and system arrangement for the required mud flow and heat load.

TR Customization

The Mud Cooling System can be supplied with customized voltage, explosion-proof electrical equipment, local or remote control, carbon steel or sour-service steel.

Certification options include ATEX, IECEx, and UL. DGMS certification is available for projects in India.

Skid arrangement, surface coating, and equipment color can also be customized.

Factory assembly and testing are available before shipment.
