钻井过程中常遇到钻井泥浆漏失,处理漏失事故要花费大量时间和材料.常用的堵漏材料按其形状分纤维状、薄片状、颗粒状和水泥浆四大类.按其来源则分为一般堵漏材料和化学绪漏剂.文中给出了聚丙烯?先胺、聚丙烯睛脲醛树脂、粗粒橡皮渣堵漏材料(HДP)、废白土渣等堵漏材料的使用及其技术经济效果的比较以及国外堵漏材料的发展方向.最后针对堵漏问题提出一点建议.
Drilling mud often encountered during the loss of leakage, handling leakage accidents to spend a lot of time and materials commonly used plugging materials according to their shape sub-fibrous shape, flake, granular and grout four categories according to their sources are divided into general Plugging material and chemical thread drain agent.The paper gives the use of polypropylene amine, polypropylene urea formaldehyde resin, coarse rubber residue plugging material (HДP), waste white slag and other plugging materials and their technical and economic effects Comparison and the development direction of foreign plugging materials.At last, put forward some suggestions on the plugging problem.
