Land Pumping & Mixing Equipment
High-energy displacement rates are important for achieving good mud displacement and cement slurry placement. Halliburton cementing units provide fast rig-up time and homogeneous slurries. Our pumping equipment provides industry-leading reliability and performance, enabling efficient cementing operations. The Elite™ trailer is Halliburton's most advanced cementing unit and features the FLECS™ control system. Halliburton also has Global Harsh-Environment Trucks with twin HT-400™ pumps on a body load unit with a combined 1,475 horsepower and FLECS Control System designed to reliably mix and displace cement slurry in rugged conditions and harsh environment.
Automatic Density Control (ADC® mixing system)
- UNIPRO™ II computer system provides automatic control over the flow rate of incoming dry material and mixing water (automatic operational mode)
- Two back up systems: (1) electrically overrides the UNIPRO II system with a potentiometer in the control stand (manual electric operational mode); (2) manual system that bypasses the hydraulic system and manually moves the water valve and cement throttling valve (manual mechanical emergency operational mode)
- Signals are received from the 3-in. mixing water flow meter and the 3-in. density meter, adjusting the incoming flow to the correct rate and density
- Allows preprogramming of up to three stages of cement blends
- Accommodates rate, density, and stage changes during the job
RCM® IIIr High-Energy Mixing System
The RCM® IIIr mixer mixes pneumatically conveyed bulk dry cement and cement material with the mixing water for a thoroughly mixed and homogenous slurry.
- Provides a linear relationship and a single control point between valve position and dry bulk material rate and water rate
- Dry cement feed rate controlled by cement throttle valve atop mixer
- Fresh water entry feed rate controlled by a rotary-jet valve located in the mixer
- Cement dust is minimized by the wetting of dust particles before they can escape to the atmosphere
- RCM Tank: Pre-mix compartment of the RCM tank receives the cement slurry, mixing it again with mechanical agitators before returning it back to the RCM IIIr mixer via the re-circulating centrifugal pump
- Designed to re-circulate slurry through Density Sensor and back into mixer to provide higher mixing energy
- Allows re-circulated slurry to mix with the incoming water and cement for more effective mixing
- Diffuses the energy of the re-circulated and newly mixed slurries to minimize air entrainment
