新型胺基聚醇防塌剂研究

RESEARCH ON NEW AMINE POLYMERIC ALCOHOL ANTI-SLOUGHING AGENT

对新型钻井液处理剂胺基聚醇AP-1的性能进行了评价。实验结果表明,胺基聚醇AP-1对钻井液流变性能和滤失性能影响不大,具有优良的页岩抑制性,它的岩屑回收率和国外聚胺产品差不多,远远高于7%NaCl、7%KCL、3%水玻璃和其他聚醚产品,而且胺基聚醇的一次、二次和三次岩屑回收率变化不大;加入AP-1后钻井液的保护油气层能力显著增强,岩心渗透率回复率提高明显。

The performance of new amine polymeric alcohol AP-1 was evaluated.The experimental results showed that the effect of amine polymeric alcohol AP-1 on rheological behavior and filtration property of drilling fluid was less,and it had good shale inhibition,its cuttings recovery ratio was higher than 7%NaCl,7%KCL,3% sodium silicate and other polyether product,and amine polymeric alcohol AP-1 could improve the core permeability and protect reservoir.
