【Abstract】 Through study on the anti-calcium work-over fluid system,the abilities of inhibiting encapsulation,resisting calcium contamination,reducing filtration loss and resisting pollution of work-over fluid are improved. The problems such as instability of wellbore and blocking are solved. Complex situation and accident incidence both are dropped.更多还原
