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

Zhou Ye Duan Yuxiu Wu Yulong Xu Huilin (Henan Petroleum Exploration Bureau,Nanyang 473132)  
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.
