Well Yingshen No.4 of Daqing Oilfield

Problem

Since the fracturing flowback fluid is featuring by "high COD, high viscosity, and high stability", improper treatment can cause serious pollution to the surrounding environment, and therefore it is an urgent pollution problem need to be solved by the oilfield. The existing treatment process of the combination station is gravity settling + multi-stage filtration. By using the existing wastewater treatment process, this kind of wastewater cannot be efficiently destabilized and separated, and may causing filter plugging, high backwash frequency, and "paralyzed" state of the system.

Pollutant

Fracturing flowback fluid

Solution

Our Company adopts the combined process of "efficient flocculant" and "deep combination flotation" and combines with the microwave device to process fracturing flowback fluid for advanced treatment, and the output water can reach the reinjection standard.

Achievement

Treatment capacity: 15 m³/h
Standard of output water: Oil content < 100 mg/l  SS < 100 mg/l  Chroma < 50 times
