Performance difference between fracturing fluid and drilling fluid

Drilling fluid is used to help the drilling process, which can protect the borehole wall and provide the required pressure, while fracturing fluid is used to inject a large amount of liquid into the borehole to help crude oil collection. 1, which means different: drilling fluid refers to multifunctional circulating fluid meeting the needs of drilling and completion engineering. Fracturing fluid is a fluid stored or injected into a well during drilling and workover operations to prevent formation fluid from being ejected. 2. Different uses: Drilling fluid is used to help the drilling process, generally used for wetting, flushing, supporting and protecting the borehole wall, and some corrosive agents and antibacterial agents are added to increase its external defense function. Fracturing fluids are used to help increase the flow of crude oil in oil and gas wells. Its main characteristics are high pressure and high viscosity, and some corrosive additives and antibacterial agents are added to prevent bacteria and corrosion.
