Experiment on the relationship between the characteristics of flowback liquid ions and the complexity of hydraulic fractures in shale

The evaluation of the effect of hydraulic fracturing is the focus of shale gas safety and economic exploitation, and evaluation of the complexity of hydraulic fractures is a major difficulty. In order to better evaluate the complexity of shale gas fracturing fractures, based on the characteristics of ion exchange between fracturing fluid and shale formation, the flowback fluid ion changes, and a c...
