摘　　要：苏北低渗注水开发油藏目前采油速度为0．58％，主要分布在台兴、腰滩等阜宁组11个油藏单元，单元储量规模大小不一，在22×10^4～171×10^4t之间，主要为砂泥薄互层层状油藏，目前开发状况不尽理想。对层系适应性、井网适应性、能量保持和利用状况、注水开发效果等方面进行了综合评价，并以台兴和腰滩油田为例，针对不同注水开发问题，提出相应的细分层系开发、井网完善、提高地层能量补充和利用等综合调整方案和思路。The low-permeability reservoirs in northern Jiangsu area that mainly diustribute in the 11 reservoir units of Funing group of Taixing, Yaotan and other areas, is currently developed by water flooding with production rate of 0.58 %. The storage units are mainly the sand-shale thin interbedding reservoirs of various capacity ranging between 22 ×10^4 and 171×10^4. This paper made comprehensive evaluation of strata series adaptability, well pattern adaptability, maintenance and utilization situation of energy, water flooding effects and other aspects of development. By taking the example of Taixing and Yaotan oilfields, this paper finally proposed the corresponding integrate adjustment solutions like sub-divided strata series development, well pattern optimization and increasing the supply and utilization of stratum energy for the various problems in waterflood development.
