| Abstract:Being the deepest depth of coring salt mine for Chongqing Bureau of Geology and Minerals Exploration, rock salt exploration well ZK0001 is completed with the depth of 3805m in Huangling mining district of Yunyang. In the core drilling process, Xinchuan 6-5 single rotary and double-tube core barrel, PDC coring bit and surface-set diamond bit were selected with strict operation procedures to overcome the difficult problems of formation fracture, well diameter shrinkage, core blocking and salting-out crystallization, the samples were collected in the interval of 3159.85～3805m with coring footage of 254.49m, the average footage for single cylinder was 13.39 meters, the coring recovery quality was excellent, and the average core recovery reached 98.1%, 53.11m rock salt in layer thickness was obtained, which could provide valuable experience for the construction of deep salt mine exploration and exploitation in this area. |
