摘　　要：随着环保形势越来越严峻,海上油田对废弃钻井液的处理从开始的“限制排放”逐步演变为“零排放”,导致废弃钻井液回收量急剧增多,严重影响海上油田开发的经济性。对此,室内对废弃钻井液的胶体稳定性进行了研究,从钻井液体系源头控制和末端处理相结合出发,构建了环保型易脱稳钻井液体系和生化处理技术,通过提高废弃钻井液固液分离效率,减少废弃钻井液的处理量,来解决目前“零排放”问题。The discharge of waste drilling fluids in offshore drilling operations has in recent years gradually become“zero discharge”from“limited discharge”implemented originally because of the stricter requirement of environment protection.This has resulted in sharp increase in the amount of waste drilling fluids recycled,which in turn badly affect reduced the cost efficiency of offshore petroleum development.A laboratory study was performed on the colloidal stability of the waste drilling fluids,and by combining the source control and terminal treatment,an environmentally friendly easy-to-destabilize drilling fluid and a biochemical treatment technology were developed.“Zero discharge”of waste drilling fluids in offshore drilling can be realized by decreasing the amount of waste drilling fluids to be treated through increasing the efficiency of solids-liquids separation of the waste drilling fluids.
