Description

Technical Field

[0002] Waste fracturing fluid is a mixed waste liquid generated during the fracturing process of oil and water wells, which comes from two aspects: one is the waste liquid returned from the formation after the fracturing operation of oil and water wells is completed; the other is the deteriorated fracturing fluid generated due to reasons such as weather and the remaining fracturing fluid after the process fails. The main components of waste fracturing fluid include thickeners (polysaccharide polymers), various additives, oil stains returned from the formation, end products after the reaction between the fracturing fluid and the formation, and organic products with smaller molecular weights generated after the fracturing fluid is broken.

[0003] During the flowback fluid treatment process, the liquid medicine is injected and mixed with the flowback fluid for treatment, and then the motor drives the stirring rod to rotate to mix the internal liquid medicine and the flowback fluid. This mixing method has low efficiency and a long treatment time for the flowback fluid. Summary of the Utility Model
