摘　　要：针对深海钻探、科学钻探以及干热岩钻探高温堵漏技术难题和对高温堵漏材料的需求,通过对国内外堵漏材料和堵漏评价仪器的研究现状分析,总结了近年我国在高温堵漏材料研发及高温评价仪器方面的研究进展,可见目前化学交联固化剂是桥接堵漏剂一种较好的补充,但在高温条件下需考虑化学材料的抗温性能;针对堵漏评价仪器方面,目前发展较为全面,为高温高压条件下的堵漏剂配方研制提供了较好的保障。This study summarizes advances in the research and development of high-temperature leak-stopping materials and high temperature evaluation instrument at home in recent years in order to meet the need for high-temperature leak-stopping technology and high-temperature leak-stopping materials in deep-sea drilling,scientific drilling and dry-hot rock drilling.The study indicates that at present,chemical cross-linking curing agent is a good bridging plugging agent,but it needs to be considered in the high temperature conditions of its temperature resistance.At present,the development of leak-stopping evaluation instrument is more comprehensive which provides a guarantee for the development of the formula of plugging agent under the condition of high temperature and high pressure.
