HumSEAL 高温封堵剂 High-Temperature Sealing Agent
简介Introduction
HumSEAL高温封堵剂是一种采用非磺化改性工艺制备的腐殖酸树脂类封堵降滤失剂。该产品在实现去磺化的同时，完整保留了腐殖酸类材料固有的抗高温降滤失特性，特别适用于环保要求严格的区域以及高温高压深井等复杂井况作业。
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.
性能及优点Performance and advantages
l 推荐加量：2.0%~5.0%；
l 可形成致密泥饼，显著降低钻井液高温高压条件下的滤失量；
l 能在井壁表面形成致密低渗透封堵层，有效稳定井壁结构。
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.
