HumSEAL 高溫封堵劑 High-Temperature Sealing Agent
簡介Introduction
HumSEAL高溫封堵劑是一種采用非磺化改性工藝制備的腐殖酸樹脂類封堵降濾失劑。該產(chǎn)品在實現(xiàn)去磺化的同時，完整保留了腐殖酸類材料固有的抗高溫降濾失特性，特別適用于環(huán)保要求嚴格的區(qū)域以及高溫高壓深井等復雜井況作業(yè)。
HumSEAL High-Temperature Sealing Agent is a humic acid resin-based plugging and fluid loss reducer manufactured through sulfonation-free modification technology. While achieving desulfuration, this product fully retains the inherent high-temperature fluid loss control characteristics of humic acid materials, making it particularly suitable for environmentally sensitive regions and complex well conditions including high-temperature high-pressure (HTHP) deep wells.
性能及優(yōu)點Performance and advantages
l 推薦加量：2.0%~5.0%；
l 可形成致密泥餅，顯著降低鉆井液高溫高壓條件下的濾失量；
l 能在井壁表面形成致密低滲透封堵層，有效穩(wěn)定井壁結(jié)構(gòu)。
l Recommended dosage: 2.0% to 5.0%;
l Forms a compact mud cake to significantly reduce fluid loss under high-temperature and high-pressure conditions;
l Creates a tight, low-permeability sealing layer on wellbore surfaces to effectively stabilize wellbore integrity.
