摘　　要：针对注水开发油田经过二次加密调整且开采一段时间后,剩余油分布具有平面上不均衡、纵向上高度分散难采度加大的特点,研究了合理井网密度、注采井距、注水方式,结果表明:大庆萨北油田北三区东部三次加密调整预测可调砂岩厚度为12.44 m,有效厚度为1.88 m;合理井网密度为50~60 口/km2,注采井距为200~250 m;采用均匀布井方式,局部调整,以保证所布井点落在剩余油富集部位.After exploring and secondary infilling for a period of time in the water-injecting oil field, the distribution of remaining oil was out of proportion from latitude and excessive dispersion from longitude, which resulted in difficulty for future exploration. In order to solve this problem we carried out the research of optimized well-disposing patterns of tertiary infilling adjustment. Investigations have been made of reasonable well spacing density, producer-injector spacing and water-injecting mode, which indicated that adjustable sandstone thickness is 12.40 m and effective thickness is 1.88 m; the reasonable well spacing density is 50-60 well/km^2; Producer-injector spacing is 200.00-250.00 m; Homogeneous well-disposing and minor adjustment were used, which assured that well sites can be located on enriching area of remaining oil.
