Abstract

Abstract

The 3000m scientific deep drilling project (JSD hole) of the west Sichuan Jiajika Lithium Mine is located in the central and northern part of the Qinghai-Xizang Plateau, with a final drilling depth of 3211.21m and the construction period of only 232d, creating a record in the field of small-bore solid mineral exploration on the Qinghai-Xizang Plateau and a national efficiency record of the same type of drilling. This article systematically analyzes the measures to improve the drilling efficiency of JSD hole from the aspects of drilling equipment and tools, drilling technology and methods,construction organization and management. The specific measures are summarized as follows:reasonable selection of drilling equipment and tools is the foundation, specific drilling techniques and methods are the key such as wire-line coring hydraulic hammer drilling technology, environment-friendly flushing fluid technology, hole accident prevention and so on, moveover, the standardized organization and management is the guarantee. The efficient drilling measures of JSD hole can provide reference for improving the drilling efficiency of deep and extra-deep hole construction in the Qinghai-Xizang Plateau.
