DEVELOPMENT OF A NOVEL OILFIELD SLUDGE-FILLED GEL PARTICLE AND FIELD APPLICATION

摘要

The standard of oilfield sewage treatment is constantly improving in recent years, new trcatmcnl technologies are cmci^ing and oilfield sludge problems that occur though water quality is a key issue that needs to be addressed. Existing treatment methods arc not able to process the increase of oilfield sludge. This study proposes a novel profile control technology with a new gel particle to fill the oilfield sludge. This new gel particle, compared with traditional particles, not only retains good dcformability, but also enhances strength, heat and salinity resistance. Its heat resistance can reach up to 110°C and its salinity resistance up can reach 200000 mg/L, its expansion rate is three to five times faster. Ttic new particle can process sludge with filling percentage as high as 50%. The properties of this new gel particle provide oilfields with a new recyclable sludge treatment technology and an economical deep profile control system.
