Part 8 Cementing Units
With 50 years experience of manufacturing cementing units, China can design and manufacture all kinds of cementing units in conformity with specified requirements of customers, such as truck-mounted, trailer-mounted and skid-mounted cementing units with double engines and double pumps or with single engine and single pump. These units are driven by mechanical transmission and hydraulic transmission, with the working pressure ranging from 5, 000-14, 500 psi, and with manual or automatic mode of slurry mixing.
In China, the annual output of cementing units is over 600 sets. These units are widely used for well cementing, flushing, water flooding and acid injection operations in the oilfields of China and are also exported to Canada, India, CIS and other countries. All series of cementing units are manufactured strictly conforming to ISO 9001.
The pressure range are 35, 40, 45, 50, 55, 70 and 100 MPa (5,075, 5,802, 6,527, 7,250, 7,977, 10,150 and 14,500 psi). The displacement ranges from 900 L/min (31.8 ft3/min) to 3, 300 L/min (117 ft3/min).
The cementing unit can be equipped with Tornado re-circulating mud mixing system or automatic mud mixing system with mud density controlled by computer at customers’ option. The whole unit is controlled by electric circuit system, hydraulic system, pneumatic system and mechanical driving system.
CPTDC can supply a complete package of cementing units include cementing unit, bulk cement truck, bulk cement tank and transport truck, manifold and water tank.
● Features
The pump is of one-piece fluid end and triplex plunger construction. The plunger surface is sprayed with nickel particle to extend the service life.
The power end is of steel plate welded construction with eccentric crank shaft for compact profile and light weight.
The hydraulic drive and the chain drive are adopted for less noise and vibration.
The pump is of high spin to increase displacement. The single pump displacement per minute is up to 2, 100 L (74.2 ft3).
The centralized control of electric, air, hydraulic and mechanical systems is adopted for convenient operation and high degree of automation.
Advanced ADC auto-controlled slurry mixing system is adopted.
The over pressure shutdown device is equipped to protect equipment and personnel under the high pressure conditions.
For the cementing unit with double engines and pumps, the displacement per minute is up to 3, 300 L (117 ft3).
The truck-mounted cementing unit is suitable for various road conditions in oilfields. Chassis are optional: Mercedes Benz, Kenworth. Volvo, IHC, Tatra. etc, Customers can specify any other chassis.
