摘要
现在钻井液用常规除硫剂均为固体,本文优选出两种液体除硫剂SL-2、BAKE,与常规除硫剂碱式碳酸锌、海绵铁进行除硫效率的对比,同时评价了不同除硫剂对钻井液性能的影响。结果表明,液体除硫剂具有较好的除硫效率,对钻井液性能几乎无影响,有利于高密度钻井液流变性能调控。
At present conventional sulfur elimination used in drilling fluid is solid, this article selected two liquid sulfur eliminations SL-2,BAKE,and compare with conventional sulfur eliminations like alkaline zinc carbonate,sponge iron,at the same time evaluated the influence of different sulfur elimination on the properties of drilling fluid.The results showed that the liquid sulfur elimination has good sulfur removal efficiency, almost no effect on drilling fluid performance,is advantageous to the high density drilling fluid rheological properties.
