System characteristics

1、An emulsified sand consolidation fluid system with low viscosity, which can be injected into the 2、The compressive strength of the consolidated body is above 10MPa;

3、The corrosion resistance of the solidified body is excellent;

4、The effective sand control period of the consolidation body is greater than 600 days.

Application situation

On October 27, 2015, the HWR micro-emulsion water-based sand consolidation fluid system was first applied in Well LHH106-K19 in Zhuang106-43 block of Shengli Laohekou oilfield, after completion of construction, the water injection was resumed on November 1, 2015, the injection level is stable at present, which there is no return of slurry after stopping injection.
