摘　　要：寨子河长9油层平均孔隙度为7.99%,平均渗透率为3.5×10-3μm2,油藏类型属于典型的低孔、特低渗弹性-溶解气驱油气藏。2010年开始寨子河长9油层实施注水开发。针对寨子河区块近几年注水开发特征,分别从井网适应性、注采比、地层压力恢复情况以及典型井组见水见效情况等方面进行了分析研究,剖析了目前寨子河长9油层注水开发面临的问题,提出了相应的注水开发技术对策。The average porosity of Zhaizihe Chang 9 reservoir is 7.99%, the average permeability is 3.5 m D, the reservoir type belongs to typical low porosity and ultra-low permeability elastic dissolved gas reservoirs. In 2010, Zhaizihe Chang 9 reservoir was developed by water injection way. In recent years, waterflooding characteristics, well pattern adaptability, injection production ratio, formation pressure recovery and typical water wells in Zhaizihe block were analyzed respectively. Some problems in the waterflood development in Zhaizihe Chang 9 reservoir were discussed, and corresponding technical measures for water injection development were put forward.
