新型射孔液ZYS-1的研制及评价

Developing of new perforating fluid ZYS-1 and its performance evaluation

在射孔作业中，射孔液质量的好坏直接关系到射孔效率的高低，新型射孔液ＺＹＳ—１ 是中原油田新近研制的一种高质量射孔液，该射孔液密度可调范围广，滤失量小，超低固相，其对岩芯污染的渗透率恢复值高，能减轻外来流体对产层的损害，可提高射孔效率，且成本低，性能稳定，有广泛的推广应用前景。

The quality of perforating fluid is very important.It depends on the perforating efficiency.A new perforating fluid ZYS-1 is developed by Zhongyuan Oilfield.The perforating fluid has features of widely adjustable density,low cost,less filtration,ultralow solid phase,performance stability and high core permeability recovery.It can lighten the damage of invading fluid to payzone and can improve perforating efficiency.The ZYS-1 perforating fluid is worth popularizing and applying widely.
