GUARD 誘導劑 Seal-Inducing Bridging Agent
簡介Introduction
GUARD誘導劑具有不同的粒徑規格，具有的不規則形狀，可以實現在裂縫中的顆粒流動轉向，形成局部流速差異，協助裂縫中的堵漏漿局部濃集，并由此快速形成局部卡點和固體段塞，并迅速擴散到裂縫整體，來有效提高地層裂縫堵漏屏障的抗剪切效果，其在200℃高溫情況下能保持良好的彈韌性。
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).
性能及優點Performance and advantages
l 推薦加量：0.5~3.0%；
l 高強度韌性材料，能在裂縫中起支撐作用，防止裂縫閉合，也可變形擠入裂縫，防止封門現象；
l 抗溫能力可達到200℃，封堵后承壓能力＞10MPa，2.0—12.0mm多種粒徑規格，適應與不同漏失情況。
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.
