Research status and suggestions on the contamination of drilling fluid by carbonate/bicarbonate
During the drilling process,the drilling fluid is often contaminated by various ions(or substances),among which the contamination of carbonate/bicarbonate(CO32-/HCO3-)is a more complex situation.This article provides an overview of the possi-ble phenomena,hazards,and contamination mechanisms of drill-ing fluid contaminated with carbonate/bicarbonate,as well as treat-ment technologies for carbonate/bicarbonate pollution,and propos-es corresponding suggestions.
