HumSEAL 高溫封堵劑 High-Temperature Sealing Agent
簡(jiǎn)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(shù)脂類(lèi)封堵降濾失劑。該產(chǎn)品在實(shí)現去磺化的同時(shí)，完整保留了腐殖酸類(lèi)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(diǎn)Performance and advantages
l 推薦加量：2.0%~5.0%；
l 可形成致密泥餅，顯著(zhù)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，有效穩定井壁結構。
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.
