摘　　要：针对新肇油田注水开发过程中暴露油井见水快，方案调整效果差的实际情况，重点分析注采系统调整井区目前注采比高的问题，通过产量确定注采比和通过地层压力恢复求得注采比，并研究了注采比的调整方法。研究结果表明，合理注采比应控制在2．10～2．26，待转注井注水6mon后进行注采比调整，注采比调整方式采用注水井层段交替周期注水或注水井交替周期注水方式。Based on early water breakthrough of oil wells during the water flooding process and the poor effect of plan adjustment in Xinzhao Oilfield,the problem that the injection-production ratio is high in well area of injection-production system is emphatically analyzed,the injection-production ratio is obtained by oil production or formation pressure recovery and the adjustment method of injection-production ratio is proposed.The results show that the reasonable injection-production ratio is from 2.10to 2.26and it should be adjusted after 6months of water flooding for converted water injection wells,the adjusting mode of injection-production ratio should be selected for alternating cycle injection for water injection wells or water injection wells.
