Problems solved by technology

[0004] At present, the comprehensive mud logging technology is mainly used in the field of oil and gas, and it has not been popularized in the exploration of in-situ leaching sandstone-type uranium deposits. However, due to the different geological conditions and mining objects of in-situ leaching sandstone-type uranium deposits and oil and gas, there is no use in the existing technology. Mud logging technology scheme suitable for in-situ leaching sandstone-type uranium deposits
At present, during the drilling construction of in-situ leaching sandstone uranium ore, it is necessary to frequently stop the drilling core, which consumes a lot of time, which makes the drilling efficiency low and reduces the efficiency of geological prospecting

Abstract

The invention discloses a comprehensive logging method for in-situ leaching sandstone type uranium ore. The method comprises the following steps: a, core-free drilling; b, rock debris logging; c, drilling fluid logging; d, X-ray diffraction total rock mineral analysis; carrying out X-ray diffraction total rock mineral analysis; e, performing natural gamma measurement; f, data acquisition; the data acquisition unit is used for acquiring measurement parameters in a drill hole; and according to the collected data, lithology is determined, and a specific stratum is divided. According to the method, the mode of combining the core-free drilling technology and the rock debris logging technology is adopted, drilling construction is carried out through the core-free drilling technology, then the target mine is found through the rock debris logging technology, the drilling efficiency is improved, and the effect of fast and direct prospecting is achieved.

Description

technical field [0001] The invention relates to the technical field of comprehensive mud logging for sandstone-type uranium ores, in particular to an in-situ leaching sandstone-type uranium comprehensive mud logging method. Background technique [0002] Mud logging is to observe, collect, collect, record, and analyze the solid, liquid, gas and other wellbore return information during the drilling process by rock and mineral analysis, geophysics, geochemistry, etc. The process of providing drilling information service. [0003] The comprehensive mud logging method is a comprehensive mud logging technology that integrates geological parameter logging, cuttings logging, and drilling engineering logging. Using this technology, various downhole parameters can be quickly obtained, which is useful for safe drilling and real-time evaluation of uranium reservoirs. Provide means, and carry out real-time monitoring, tracking, and early warning of the drilling process. At present, tra...
