摘　　要：高强度可溶复合材料在井下工具中的应用为近两年发展起来的新技术,目前主要应用于分段压裂工艺,形成了可溶压裂球、可溶压裂球座、可溶压裂桥塞等多种工具。解决了目前分段压裂技术应用过程中球无法返排出、生产通径小、压后需钻塞等问题。The application of high-strength soluble composite in the downhole tool is a new technology developed in the last two years,which was mainly used in the fracturing process,the formation of soluble fracturing ball,ball,soluble soluble fracturing fracturing br idge plug and other tools. The staged fracturing technology application process cannot drain,ball production of small diameter and pressure re quired to solve the problems such as the draining difficulties,small diameters,needing plug after pressed.
