摘　　要：水基洗井液的应用和实验室研究结果表明，渗入到地层中的洗井液滤液及其固相颗粒是使地层储集性能变差的主要原因。文中阐述了水型、搀入各种药品的洗井液添加剂及地层压力对储层的影响，提出了改善储层性能的方法。最后指出，同时利用酸化处理的射孔工艺有可能以最佳方式形成射孔孔道，通过酸化的作用使孔道加深并净化，从而恢复地层正常的渗透率。Water-base washing fluid's application and laboratory research results indicate that washing fluid filtrate to seep into formation and its solid phase particles are the main reason to make reservoir performance worse. This paper expounds the influence of water type,washing fluid mixed with additives and formation pressure to reservoir,and gives the method to improve reservoir performance. Finally,the author points out that perforation technology with acidization treatment is possib1e to form perforation tunnels with optimum pattern. Acidization treatment will deepen and clean the perforated tunnels,and the initial-permeability of formation would be restored.
