Hydraulic fracturing radioactive source tracing technology based on hydraulic fracturing tracing mechanics model

Abstract In response to the problem that traditional hydraulic fracturing technology is difficult to describe the specific situation of ground fissures, this study proposes to introduce a mechanics model of fracturing disappearance and optimize the model in order to achieve accurate description of the distribution of ground fissures after hydraulic fracturing. The model is validated and analyzed through case studies, and it is found that stress sensitivity, invasion factor, and retention factor all have varying degrees of influence on the tracing process. In addition, the model can accurately infer the fractures of hydraulic fracturing wells, with a variance of 148.9, a coefficient of determination of 0.81, and a root mean square error of 1.87. In terms of production, the oil production reaches 104.2 m 3 , accounting for 20.4% of the total oil production, and the water production reaches 47.6 m 3 , accounting for 15.8% of the total water production. In the examination of economic and environmental benefits, it is found that the model proposed by the research reduces labor expenditure costs to 292,000 yuan, equipment costs to 392,000 yuan, chemical supplies costs to 217,000 yuan, and maintenance costs to 98,000 yuan, but the revenue increases to 1.34 million yuan, and environmental satisfaction reaches 81.4%. The comprehensive results indicate that the model can be well applied in the tracing technology of hydraulic fracturing radioactive sources.
