I: Ultra-fine water treatment in oil and gas fields

油田水处理技术 The ceramic membrane integrated system is used to treat oily wastewater in oil and gas fields, and qualified reinjection water is obtained at one time (reaching A-level index in SY / T5329-2012 standard). With the continuous development of oil and gas fields, the quality of produced water is becoming more and more complicated, and the difficulty of processing is becoming more and more difficult. Traditional backwash filters are prone to filter sintering. Large area and other issues, and the ceramic membrane system uses the "cross-flow" filtration method, which has the characteristics of high filtration accuracy, short process, small footprint, high integration, and stable water output. It has been confirmed by field trials and engineering cases. It has good treatment effect on water produced by water flooding, polymer flooding and ternary composite flooding. Application fields: ① produced water in oil field ② fracturing fluid back to flow ③ drilling waste fluid ④ produced water in gas field

II: Conventional waterflood sewage membrane treatment in oil fields

Conventional water flooding technology is widely used in China's onshore and offshore oilfields. For low-permeability and ultra-low-permeability reservoirs, the water injection quality directly affects the development effect of the oilfield. The ceramic membrane process is used to finely treat water flooded oily wastewater (patent number: 102225812A), and the effluent quality reaches the Class A standard.

3: Oilfield polymer-containing / ternary composite flooding wastewater treatment

Due to the complex composition of the polymer-containing sewage, it has the characteristics of high viscosity, high degree of emulsification, complex composition, and difficult biodegradation, etc. The traditional process cannot meet the needs of oilfield production. When the pretreatment + ceramic membrane combined process is used to treat poly-containing wastewater (patent number: 104071919A), the oil and particulate suspended matter in the poly-containing wastewater are removed in one step to meet the water injection requirements of low-permeability oil fields.
