Clean up additive

After the fracturing construction of the oil and gas Wells, the fracturing fluid entering the formation needs to be broken and discharged quickly to reduce the damage of the fracturing fluid to the formation. Due to the effect of capillary resistance in the formation pores, the fracturing fluid is difficult to return. It is necessary to add drainage aid to the fracturing fluid to reduce the surface tension or interface tension of the well solution, which contributes to the rapid backflow of the well liquid. It is necessary to add the drainage aid to reduce the surface tension or interface tension of the well solution, which is conducive to the rapid backflow of the well liquid, reduce the damage to the reservoir and improve the construction effect. Fluorocarbon relief agents have a lower surface tension than non-fluorocarbon relief agents.
