Abstract:The red bed in southern Jiangxi is an area with serious shortage of groundwater, the CGS commenced the hydrological survey and water exploration for the purpose of achieving poverty alleviation. However, it still restricts the rural revitalization. The results of the previous geological work is verified and the key technologies of the water storage structure drilling technology in the red bed area are summarized through the emergency water search and well drilling project in 2021. The water storage structures of red bed in southern Jiangxi are generally fractured and severely broken formations, lead to traditional hydrological drilling techniques has low drilling efficiency and bad well completion. According to the successful application of air down-the-hole(DTH) hammer drilling technology in these typical structures , the key points of drilling and well completion techniques are summarized, which would improve the efficiency and quality of hydrological drilling and conducive to socio-economic benefits.It is hoped to provide a certain technical reference for drilling in the red bed area.
