| Deep coring drilling is one of the important challenge in the field of drilling engineering. Implementing deep coring drilling in the complex strata in the karst area of Guizhou province is more and more difficult. In this paper, it summarizes the on-site working experience of deep coring drilling in complex strata in karst areas of Guizhou province, and forms a relatively mature and complete technical process system for deep coring drilling, with the selection of deep coring drilling rigs, the design rules of borehole configuration, the matching of drill pipes and drill bits, the drilling fluid system and the typical accident handling tools as the core contents. This technical system can effectively ensure the construction safety of deep coring drilling holes at depths of 1000m to 3000m in complex strata of karst areas in Guizhou province, it also can provide reference for deep coring drilling work in karst areas for both domestic and overseas. |
