摘　　要：地质勘探套管钻进技术中的专用套管是实现套管钻进的关键因素之一。本文介绍了在地质勘探套管钻进过程中,专用套管作为绳索取心钻杆,传递钻压和扭矩,钻进结束后,作为技术套管留在孔内,恢复护壁套管功能。通过室内试验完成专用套管结构、材料及加工工艺等的选型和研制,且经过实际野外应用效果良好。The special casing is one of the key factors for geological prospecting casing drilling technology. In the process of casing drilling in geological prospecting, the special casing is used as a wire-line drilling pipe to transfer the drilling pressure and torque; after drilling, it is kept in hole as technical casing with casing function. The selection and development of the special casing structure, material and processing technology are completed through indoor tests and the effects are obvious in field application.
