极地冰盖深部“暖冰”层钻进时，由于冰层的温度较高，接近甚至达到冰的压力熔点，回转钻进时产生的切削热量极易使冰屑融化，导致机械钻速慢、取心率低、卡钻事故频发。钻压、转速、切削具结构等参数均对切削热量有一定的影响，有必要设计一套实验装置对切削热量进行测试，从而为设计切削具结构、优化钻进参数组合提供理论依据。以XY-1型岩心钻机钻进系统为平台，利用无线信号传输原理设计了冰层回转钻进切削热量测试实验台。初步测试结果表明，该实验装置能够准确测量钻压、扭矩、切削温度等参数，可用来进行相关的实验研究。

Cutting heat generated during rotary drilling is extremely easy to melt ice located in warm ice layer of deep ice cap because the high temperature is almost close to or even reach ice pressure melting point, which results in low penetra-tion rate, poor core recovery and frequent sticking accidents.So it is necessary to design a device to test the cutting heat which is influenced by WOB, rotation speed and the structure of cutting tool;the test results would provide the theoretical basis for the design of cutting tool structure and optimization of drilling parameters.With the XY-1 core drilling system as the platform, using the wireless signal transmission principle, the test stand for testing cutting heat generated during rota-tional drilling in ice layer is designed.Preliminary test results show that by this experimental device, the parameters of WOB, torque and cutting temperature can be accurately measured, which can also be used for the related experimental study.
