摘　　要：牵引器输送射孔技术是牵引输送技术与多级射孔技术相融合的一种射孔技术,它既可以替代连续油管传输射孔技术,实现水平井首段射孔,又能与泵送分簇射孔作业实现无缝对接,可以为页岩气水平井射孔提供高效手段。介绍了牵引器输送射孔技术的原理和特点。同时指出,无专门管串设计分析软件、无标准测试操作流程以及无异常处置经验是当前牵引器输送射孔技术应用中存在的主要难点。通过对川南页岩气水平井的应用研究,给出了安全可靠的解决措施,为牵引器输送射孔技术的推广应用提供技术保障。Tractor conveyed perforation is a kind of perforating technology that combines tractor conveyed technology with multi-stage perforating technology,which can not only replace coiled tubing conveyed perforation in first section of horizontal wells,but also achieve seamless docking with plug and perforation operation,provides an efficient means for the horizontal shale gas well perforation.The principle and characteristics of tractor conveyed perforation were introduced and analyzed.At the same time,it is pointed out that the main difficulties in the application of tractor conveyed perforating technology are the absence of professional design and analysis software for the string,the absence of standard test and operation procedure and the absence of experience for abnormal disposal.As the study on the first application of shale-gas horizontal wells in South Sichuan,the safe and reliable solution was given,which could provide technical guide for the popularization and application of tractor conveyed perforating technology.
