Application of Water-base Clay Free Low Solid Drilling Fluid in Zhenjing Work Area

Abstract:

Water-base clay free low solid drilling fluid was applied in Zhenjing oilfield to shorten drilling period, improve operation efficiency, shorten the soakage time of the reservoir with drilling fluid and reduce the reservoir damage caused by drilling fluid. It was proved by practice that the drilling fluid could effectively control the complicated situations in downhole with increased drilling speed and lowered drilling cost.
