DriSEAL 随钻堵漏剂 Lost Circulation Material for Drilling
简介Introduction
DriSEAL主要由颗粒状和短纤维状材料按不同的粒径、比例复配而成的******复合型堵漏材料。主要用于随钻堵漏，粒径可根据实际需求调整，通常为60目以细。
DriSEAL is a highly efficient composite plugging material primarily composed of granular and short-fibrous materials, blended in varying particle sizes and ratios. It is mainly used for plugging while drilling, with the particle size adjustable according to actual requirements, typically finer than 60 mesh.
