摘　　要：通过对国内外压裂滑套不限级设计方式的调查研究,重点论述了依靠井下开关工具组合、机械结构限位计数以及智能电控系统触发3种方式实现压裂滑套不限级设计的基本原理与研究进展。从利用齿槽结构、键槽结构等特征结构在压裂滑套轴向或周向上的尺寸变化、数量变化以及尺寸和数量组合编码3个方面对压裂滑套的不限级设计方式进行了展望。The infinite design modes of fracturing sliding sleeves at home and abroad were investigated and studied,particularly the basic principle and research status of realizing the infinite design of fracturing sliding sleeves by relying on three modes:downhole switch tool combination,mechanical structure limiting and counting,and intelligent electronic control system triggering.In addition,the infinite design modes of fracturing sliding sleeves prospected from three aspects:the size change,quantity change,and size and quantity combination coding of the fracturing sliding sleeve in the axial or circumferential direction of the characteristic structure such as the tooth slot structure and the keyway structure.
