固井

多年来,人们已成功将KURARAY POVAL™用作降失水剂以进行油井固井。该聚乙烯醇添加剂有助于节约成本,且未对水泥凝结时间造成延迟影响。因此,它使得油井施工变得快速、高效。

优势

  • 减少API标准固井过程中的失水
  • 与其它水泥添加剂有很好的相容性
  • 成本低于其他降失水剂

其他油田应用

  • 水力压裂
  • 可溶性油工具

性能

  • 优良的粘结剂
  • 减少失水
  • 减少固井过程中的产水
  • 与其它水泥添加剂兼容

用途

  • 适于油井固井作业的添加剂

KURARAY POVAL™ resin, when mixed with cement powder, water, dispersant and defoamer, will prevent fluid loss to the formation in cementing operations. KURARAY POVAL™ is an excellent binder, reduces fluid loss, reduces water production in the cementing process, and is compatible with other cement additives. It contributes to cost savings by enabling fast and cost-efficient oil well construction and has shown no retardation effect on the cement setting time.
