Traditional sand and liquid supply equipment can no longer meet current construction needs.In this paper,an automated sand and liquid integrated equipment has been developed,integrating sand conveying,sand storage,and sand mixing systems,and greatly increasing parameters such as displacement and sand adding rate.The test results show that the maximum displacement of the sand-liquid integrated equipment is 30 m3/min,and the maximum sand adding rate is 12 m3/min.It realizes the entire closed transportation of fracturing proppant,as well as one-click operation of sand supply and fracturing fluid supply.This equipment can meet the all-round requirements of large-displacement liquid supply,sand addition of multiple types of large sand volumes,green,safety,and intelligence in large-scale shale gas fracturing construction.
