FENG Jian-guo;No.701 team of the Xinjiang Uygur Autonomous Region Nonferrous Geological Exploration Bureau;  
With the continuous development of China's economy and the growing demand for resources, the drilling technology requirements are increasingly high, the traditional drilling technology has been unable to meet the actual needs of modern drilling, deep hole drilling technology has gradually become the focus of attention. The difference between the traditional deep hole core drilling and core drilling is not only reflected in the increase of deep hole drilling, but also increase the cost and difficulty in drilling unit, therefore, the use of technical measures to ensure the scientific drilling construction, has very important significance on drilling quality.
