摘要
Air drilling is the drilling process by taking air as medium to replace drilling mud for carrying cuttings back to the surface. Such a process may affect the authenticity of cuttings and cause the difficulties for lithologic discrimination or identification, including the lithologic naming, the stratigraphic classification, the engineering forecast and oil-gas-water layer discovery, etc. This paper proposes the improved measures for logging methods under the air drilling conditions performed in Junggar Basin, which could be used for reference for further logging technological improvement under air drilling conditions in the future.
