多功能抗污染剂在老挝农波矿区南部钾盐钻探中的应用

多功能抗污染剂是一种膨润土有机改性冲洗液材料,可用于配制盐水和镁基冲洗液体系。该冲洗液材料在老挝农波矿区南部的成功应用,证明其具有较强的耐盐及抗污染能力,较强的抑制泥岩水化分解作用,较好的护壁及保心作用,尤其适合在有石盐(岩盐)、钾石盐、光卤石等易溶盐存在的地层中使用。

Application of Multifunctional Antipollution Agent for Potash Drilling in Laos

The multifunctional antipollution agent is a kind of flushing fluid material made of organically modified bentonite, which can be used to prepare salt water and magnesium based flushing fluid system. This flushing fluid material was successfully applied in a mine of Laos, which indicates that it has strong salt tolerance and antipollution ability, strong inhibition of shale hydration decomposition, effective wall and core protection, especially is suitable for the use in the formations containing the soluble salts of halite (rock salt), sylvite and carnallite.
