| 摘 要： | 本文讨论了水平井酸化对酸液体系的基本要求。除酸液缓速、防粘土膨胀、铁离子稳定，破乳助排等与直井酸化相同的要求外，水平井酸化中使用的酸液体系应在长时间内保持低腐蚀速度，不产生点蚀，降阻效率高，而且要实行转向酸化。报道了新开发的碳酸盐岩油藏水平井酸化用的两种添加剂的应用性能具有良好缓蚀性能并兼有破乳、降低表面张力等多项性能的多功能复合添加剂SHS-1；不溶于酸而溶于油的悬浮液型转向剂(酸化暂堵剂)SHS-2。

MULTIFUNCTIONAL
CORROSION INHIBITOR SHS-1 AND DIVERTING AGENT SHS-2 FOR USE IN HORIZONTAL WELL ACIDIZING
OF CARBONATE RESERVOIRS |
| |
| Abstract: | An analysis is given to
the basic requirements to cacidizing fluids used in horizontal wells of carbonate
reservoirs. It is stated that the unique requirements are long-time low corrosivity, no
pitts, high friction reduction, and need in flow diverting besides of common ones
retarded acidization processes, stabilization of clays and ferroferric ions,
demulsification, backflow promotion, etc. The performance properties of a multifunctional
compounded additive, SHS-1, mainly for corrosion inhibition in mixed hydrochloric
acidizing fluids and an acid-insoluble and oil-soluble diverting agent in suspension,
SHS-2, for pretreating the borizontal wells are described. |
