摘　　要：目前CobraMax压裂技术通过连续油管水力喷砂射孔,从环空进行主压裂施工,并通过砂塞分隔各压裂层,所有层位施工结束后使用连续油管液氮冲砂。使用该工艺可以提高压裂的针对性,不使用封隔器分层,在理论上不受分层级数的限制。在介绍该工艺的原理和在合川两口井的现场实施情况基础上,对施工进行了分析总结,为该工艺下一步更好的应用提出了一些建议。CobraMax fracturing technology,by coiled tubing hydraulic jet perforation,is done main fracturing operation from the annulus,and separates the fracturing layer by sand plug,washes sand with coiled tubing in liquid nitrogen after all the layers to be fractured.Using this process can improve the fracturing targeted and without using packer to separate layers,in theory,not restricted by separated grades.Based on the principle of the technology and the field application in two wells of Hechuan gas field,the construction has been analyzed and summarized,and some suggestions for a better application at next step is suggested.
