Efficient seawater slurry bentonite and additive thereof
The efficient seawater slurry bentonite is characterized in that a proper amount of sodium carbonate is added into calcium bentonite raw ore to produce sodium bentonite, then a proper amount of the additive is added into the sodium bentonite, and the sodium bentonite and the additive are uniformly mixed to produce a finished bentonite product for efficient seawater slurry making; the additive is prepared from the following components in percentage by mass: xanthan gum, a salt-resistant synthetic polymer and high-viscosity sodium carboxymethyl cellulose; the salt-resistant synthetic polymer can be high-viscosity polyacrylamide, a sulfonic acid group synthetic polymer tackifying filtrate reducer, a zwitterionic polymer tackifying filtrate reducer, a synthetic polymer tackifying filtrate reducer and the like, and xanthan gum and the salt-resistant synthetic polymer are compatible to form a synergistic additive, so that a very good synergistic tackifying filtrate reducer effect can be achieved; the seawater slurry bentonite and the additive thereof are suitable for offshore drilling or capital construction engineering, seawater is directly taken for slurry making, and great convenience is provided for construction.
一种高效海水泥浆膨润土及其添加剂，其特征是：所述的膨润土首先由钙基膨润土原矿添加适量纯碱生产出钠化膨润土，然后在钠基膨润土中添加适量添加剂混合均匀，即可生产出高效海水造浆用膨润土成品；按照钠基膨润土质量百分比计，添加剂由以下组分构成：黄原胶，抗盐型合成聚合物及高粘羧甲基纤维素钠；抗盐型合成聚合物可以是高粘聚丙烯酰胺，磺酸基的合成聚合物增粘降滤失剂，两性离子聚合物增粘降滤失剂，合成聚合物增粘降滤失剂等，黄原胶和抗盐型合成聚合物配伍为增效添加剂，可以达到很好的协同增粘降滤失的效果，本发明海水泥浆膨润土及其添加剂适合海上钻井或基建工程使用，直接取海水造浆，为施工提供很多方便。
