摘要

通过取换套防钙侵修井液体系的研究，提高了修井液的抑制包被能力、抗钙侵能力、降滤失和抗污染能力，解决了井壁失稳和阻卡等问题，降低了复杂情况及事故发生率。

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.
