安棚深层系凝析气井射孔压井液技术研究

Study of Perforation and Kill Fluids of Gas Condensate Well in Anpeng Deep Formation

介绍了一种保护油气层的射孔压井液技术 ,该技术所用的配方具有低密度、低表面张力且具有较强的防膨能力等特点。在安棚深层系低孔低渗油田安 30 0 3等凝析气井作业中现场试验 ,解决了安棚深层系低压气井的水锁伤害等问题 。

This paper presented a kind of perforation and kill f luids,which was characterized in low density,low surface tension and stronger antiswelling ability. Serial field trials showed the compositions could prevent water block damage in low pressure gas wells of Anpeng deep formation,and provi de better reference to research and application of well entry fluids in low poro sity,low permeability oil-gas-fluids.
