Development of the multi-parameter combination logging probe for sandstone type uranium deposits
摘要
Abstract
In response to the need for multiple logging measurements in sandstone type uranium deposits in China,as the drilling depth increases,the drilling time and cost increase,and there are risks such as collapse and pipe jamming,it is proposed to develop a multi parameter combination exploration tube that meets the logging requirements in the exploration stage of sandstone type uranium deposits.By optimizing parameters,the mutual interference between parameters such as trilateral resistivity and natural potential was solved.A digital and modular independent control and independent response parameter module was developed.Combined with connection structure design and the development of a multi parameter independent response parallel working mechanism,the ultimate goal was to achieve well temperature,wellbore inclination,wellbore diameter,natural gamma,natural potential,trilateral resistivity,acoustic wave,wellbore diameter,and quantification gamma combination probe with multiple parameters,including gamma the logging module has passed the metrological verification and obtained the verification certificate.Through logging applications,the developed multi parameter combination exploration tube can achieve the purpose of obtaining multiple logging data in one well operation,improve the efficiency of sandstone type uranium logging operation,reduce costs,and meet the needs of efficient and low-cost development.Moreover,the parameters of the multi parameter combination exploration tube have high recognition ability at the rock interface,and have a significant indication effect on the lithological changes of interactive thin layers,interlayers,and other formations.关键词
