GUARD 诱导剂 Seal-Inducing Bridging Agent
简介Introduction
GUARD诱导剂具有不同的粒径规格，具有的不规则形状，可以实现在裂缝中的颗粒流动转向，形成局部流速差异，协助裂缝中的堵漏浆局部浓集，并由此快速形成局部卡点和固体段塞，并迅速扩散到裂缝整体，来有效提高地层裂缝堵漏屏障的抗剪切效果，其在200℃高温情况下能保持良好的弹韧性。
GUARD Seal-Inducing Bridging Agent features multi-grade particle sizes with irregular geometries, enabling flow diversion within fractures to create localized velocity differentials. This promotes concentrated accumulation of lost circulation material (LCM) slurry in fracture zones, facilitating rapid formation of localized bridging points and solid plugs. These plugs subsequently propagate throughout the entire fracture network, significantly enhancing the shear resistance of fracture sealing barriers. The product maintains excellent elasticity and toughness under high-temperature conditions up to 200°C (392°F).
性能及优点Performance and advantages
l 推荐加量：0.5~3.0%；
l 高强度韧性材料，能在裂缝中起支撑作用，防止裂缝闭合，也可变形挤入裂缝，防止封门现象；
l 抗温能力可达到200℃，封堵后承压能力＞10MPa，2.0—12.0mm多种粒径规格，适应与不同漏失情况。
l Recommended dosage: 0.5-3.0%；
l It is a high-strength and tough material that can provide support within fractures, preventing fracture closure. It can also deform and squeeze into fractures to avoid the "screen-out" phenomenon (blocking of the wellbore due to excessive particle accumulation);
l Its temperature resistance can reach up to 200°C, and the pressure-bearing capacity after plugging exceeds 10 MPa. It is available in various particle size specifications ranging from 2.0 mm to 12.0 mm, adapting to different types of lost circulation scenarios.
