PCS-421B Cementing Equipment Skid Mounted Auto Density Control Double Pump SJS SERVA
Skid mounted cementing units are widely deployed for offshore operations and remote onshore working scenarios, including desert zones that are inaccessible to conventional transport vehicles. The equipment offers flexible pump configuration options covering three mainstream cementing plunger pump models: TPA400, TPH400 and TPB600, with assorted plunger sizes adaptable to diverse field working conditions. WhatsApp+8615972752793 The whole unit is engineered with full-range anti-corrosion treatment to suit long-term offshore service environments. In accordance with the unique operational features of offshore platforms, a complete Zone-II explosion-proof version of the cementing skid is also available.
1. Overview
The PCS-421B is an integrated skid-mounted mixing and pumping unit featuring advanced continuous mixing performance and precise automatic density control technology. It serves as a high-end optimized solution for modern oilfield cementing operations.
The complete unit integrates a rigid skid frame, dual engines, two sets of transmissions, a pair of TPA400 triplex pumps, full hydraulic system, high and low pressure pipeline systems, as well as the ACM automatic mixing system. The high-energy mixing system is driven by power take-off (PTO) from the two transmissions. WhatsApp+8615972752793 Benefiting from its highly integrated and compact structural layout, the skid unit is perfectly suited for installation and operation on space-limited offshore drilling platforms.Luben@youlongpetro.com
This versatile skid equipment is applicable for multiple oilfield working services, including well cementing, acidizing treatment, oil well pressure testing and various fluid pumping tasks for offshore, onshore and desert oilfield sites.
