哈里伯顿已将 SentinelCem Pro 水泥系统添加到其堵漏解决方案产品组合中。单袋包装可实现在海上和偏远地区的主动存储。

SentinelCem Pro 水泥以其前身为基础，简化了混合操作，因为它无需对浆料设计进行预水合，也无需获取高纯度水源。此功能可以选择直接在运行中或在批量混合器中混合系统，从而促进更高效的钻机操作。

“大部分循环是造成建井过程中非生产时间 (NPT) 成本高昂的主要原因。 SentinelCem Pro 水泥安全地泵入井底组件，帮助客户快速解决漏失事件并减少 NPT，”哈里伯顿固井副总裁 Matt Lang 说道。

SentinelCem Pro 水泥的触变性质使系统在泵入失循环区域时保持流体状态，并在泵停止时快速凝胶。这一功能使系统能够深入裂缝和孔隙地层，以减少地层中昂贵的钻井液损失。该系统的早期抗压强度开发能够快速恢复钻井作业。

Halliburton has added the SentinelCem Pro cement system to its lost circulation solutions portfolio. The single-sack packaging enables proactive storage in offshore and remote locations.

SentinelCem Pro cement, built upon its predecessor, simplifies mixing operations as it eliminates the need for pre-hydration of the slurry design and access to high-purity water sources. This feature facilitates more efficient rig operations with the option to directly mix the system on the fly or in a batch mixer.

“Lost circulation is the main contributor to costly nonproductive time (NPT) in well construction. SentinelCem Pro cement safely pumps through the bottom-hole-assembly to help customers quickly address lost circulation events and reduce NPT,” said Matt Lang, VP of Cementing, Halliburton.

The thixotropic nature of SentinelCem Pro cement allows the system to stay fluid while pumped into lost-circulation zones and to rapidly gel when pumping stops. This feature enables the system to penetrate deep into fractures and vugular formations to mitigate costly drilling fluid loss to the formation. The system’s early compressive strength development enables a quick return to drilling operations.
