Drilling fluid system name

Drag reduction completion fluid system

Matching core finishing agent

Corrosion agent HRS/HDB    Clay stabilizer HCS    Corrosion inhibitor CA101-3    Drag reducing agent HUL

System characteristics

1、The corrosion is small;

2、It has strong inhibition and good swelling resistance, which can effectively prevent water damage and particle migration damage.

3、The compatibility is good, while it has good compatibility with reservoir fluid and pre working fluid;

4、It can relieve or reduce the reservoir damage that caused by the incompatibility between the previous working fluids, while the reservoir protection effect is good;

5、It can reduce the heavy oil flow resistance and oil liquid interfacial tension, which can improve heavy oil seepage characteristics and increase production.

Application situation

It has been applied in the SZ36-1 and QHD32-6 heavy oil fields in the Bohai area. The field results show that the completion fluid can significantly reduce the viscosity of heavy oil, reduce the resistance of oil flow, protect reservoirs and increase production capacity.
