摘　　要：近年来,作为入地最为关键手段的钻探所面临的地层越来越复杂,钻孔垮塌、掉块、缩径和超径等事故发生概率增加,严重制约了钻探工程质量与效率的提升。护壁堵漏材料是钻探工程不可或缺的关键性工程材料,护壁堵漏技术则是保证钻进工作安全、快速以及持续进行的重要技术环节,是复杂地层钻孔处理的主要内容。本文从科普的角度介绍了护壁堵漏材料的基本概念与组成、冲洗液护壁堵漏作用、水泥基材料护壁堵漏作用、护壁堵漏材料的进一步发展空间等,以期加深对护壁堵漏材料的认识,促进新型护壁堵漏材料的研发和应用。In recent years,as the most important means to access into the earth,drilling is facing the problems that the formation is becoming more and more complex,and the probability of drilling collapse,falling blocks,diameter reduction and over⁃diameter accidents is increasing,which seriously restricts the improvement of the quality and efficiency of drilling engineering.Wall protection and plugging material is an indispensable key engineering material for drilling engineering and the wall protection and plugging technology is an important technical link to ensure safe,fast and continuous drilling work and is the main content of drilling treatment in complex formations.From the perspective of science popularization,this paper introduces the basic concept and composition of wall blocking materials,the wall blocking effect of flushing fluid and cement⁃based materials and the further development space of wall blocking materials,so as to deepen the understanding of wall blocking materials and promote its R&D and application.
