摘　　要：压裂是国内外各油田对储层进行改造并行之有效的一项技术措施,但在压裂过程中出现的卡钻事故严重制约着施工的进度和压裂质量。在轮古××井进行油管拖动分层喷射射孔和酸压新工艺的先导实验过程中,环空里的压裂砂堵导致砂卡。介绍了该井砂卡的处理过程,分析了砂卡的原因,并给出了处理类似水平井井下复杂情况或事故的注意事项。Fracturing is a technical measure of treatment to reservoir and the effective transformation in each oil field at home and abroad.But in the process of fracturing,stuck accident severely restricts the progress and quality of the fracturing operation.At Lungu× ×well, during the pilot test of layered jet perforating process dragged by tubing pipe and new acid fracturing technology,fracturing sand from annulus resulted in plugging.The paper Introduces the process of the well sand stuck,analyzes its reason,and gives out some considerations about dealing with similar down-hole complicated cases and accidents.
