Gilsonite in Workover and Completion Fluids
Workover and completion operations use fluids that must control the well without damaging the reservoir. Gilsonite can play…
用于油基和水基钻井液的高温高压降滤失剂和页岩稳定剂。
主要优势
- 降低高温高压滤失量
- 稳定页岩和微裂缝
- 降低扭矩、摩阻和卡钻风险
- 150°C以上性能稳定
产品概述
钻井用硬沥青研磨至约200目，提供多个软化点范围。在井底温度下，颗粒软化并封堵孔隙和微裂缝，从而降低高温高压滤失量、稳定页岩并改善润滑性。
应用领域
- 油基和合成基钻井液
- 水基钻井液（配合分散剂）
- 防漏堵漏浆
- 水平井和高温高压井
