摘　　要：连续油管带底封喷砂射孔环空分段加砂压裂技术是集喷砂射孔、水力喷射压裂、环空加砂、连续油管拖动转层等技术于一体的新型增产措施,具有转层灵活、施工时效高、施工后井筒清洁等优点。在分析喷砂射孔、喷射压裂、定位和转层基本原理的基础上,介绍了连续油管带底封喷砂射孔环空分段加砂压裂技术的工艺特点和现场实施流程,并以一口试验井为例,介绍了该技术的工艺设计方法和现场实施情况。试验井用3 d时间完成了8段的加砂压裂,压裂后日产气35.5×104m3,增产效果显著。The annulus staged fracturing technology with bottom sealed sandblast perforation by the coiled tubing is a new production measures integrated with sand blasting perforation,hydraulic fracturing,injection annulus sand,coiled tubing drag layer,has advantages of being flexible of transfer layer,high efficiency of operation,clean of wellbore after operation. Based on the analysis of sand blasting perforation,jet fracturing,positioning and transfer layer,characteristics and field implementation process of the annulus staged fracturing technology with bottom sealed sandblast perforation by the coiled tubing is introduced,and taking a test well as an example,the technical process design method and implementation gas been introduced. The test well is completed to 8 stages of sand fracturing in 3 days,nissan gas reaches 35. 5 × 10^4m^3 after fracturing,and increase yield is significantly.
