现行绳索取心口径系列主要适用于3000 m以内浅钻孔。在4000 m左右的特深孔绳索取心钻进中，存在一定的技术“瓶颈”，如地层复杂，甚至无法安全钻达设计深度。论证3000～5000 m特深孔绳索取心合理口径系列和钻柱方案是为特深孔成套钻探装备研制、绳索取心钻具开发提供技术依据的重要前期工作，也是一项公益性和开放性的技术工作。简述了特深孔绳索取心口径系列及钻柱方案的初步设想，期望国内钻探专家、一线技术人员广泛参与，进一步论证。

The existing diameter series for wire-line coring are mainly suitable for shallow drilling with a depth of less than 3000 m.There is technical bottleneck such as that the designed depth cannot be reached in complex formation, when the wire-line coring is performed at a depth of about 4000 m.The demonstration on reasonable diameter series and drill pipe scheme for wire-line coring in ultra-deep borehole at the depth between 3000 m and 5000 m is an important preliminary work which can provide technical base for the development of ultra-deep borehole drilling equipment and drilling tools for wire-line coring.And it is also a public welfare and open technical work.This paper summarizes the preliminary ideas on diameter series and drill pipe scheme for wire-line coring in ultra-deep borehole with the expectation that it could receive wide participation and further demonstration from the drilling experts and technicians in China.
