胜利油田注水井增注技术新进展
胜利油田主要以注水开发为主，油田现有欠注层1954层，日欠注8．6×10^4 m^3，其中低渗欠注层576层，日欠注1．2×10^4^m3。对国内外解堵增注技术主要进展进行了阐述，对胜利油田近年来在注水井增注方面进展情况进行总结，针对不同欠注原因实施了相应的解堵增注措施，主要有在中高渗储层实施了以盐酸、土酸为主的酸化解堵增注措施，在低渗油田中实施了解堵、基质处理及活性降压增注工艺技术，在物理增注方面，主要实施了水力深穿透射流射孔、水平井径向钻进技术、振动解堵增注技术，配套了前期预处理及后期排液等配套技术，并简要进行了对比分析。在新技术应用方面，主要对表面改性降压增注技术、脉冲解堵增注技术试验应...
