摘　　要：为解决钻开产层的油层保护技术问题,介绍了辽河油田利用屏蔽暂堵原理将钻井液改造成完井液的油层保护技术,它用清水滤失量降低率进行室内评价,并采用与可比条件十分接近的现场评价法,验证该技术的实施效果。该技术适用范围广,适合各种井型和油气藏类型,且简单易行。在15个区块433口井的应用中,取得了显著的经济效益和社会效益。To satisfy the demand of reservoir protection , drilling fluid was improved to well completion fluid based on the principle of shielding temporary sealing . Three treating methods are given against the characteristics of Liaohe oil field . It is shown that this method has the advantage of easy and cheap .
