摘　　要：胡十二块属于严重非均质油藏 ,经过十几年的注水开发 ,目前开发面临着高含水、低采出的问题。为了更好地提高区块的注水采收率 ,运用室内试验资料、国内外经验公式及矿场资料 ,用多种方法对胡十二块注水采收率进行了预测。经分析研究后认为 :胡十二块具有提高注水采收率的潜力 ,应在提高注水波及体积上做工作 ;并提出了胡十二块今后进行区块治理要运用细分层系开发、对局部井网进行注采关系完善、层内调剖及三次采油等常规方法 ,来扩大注水波及体积 。Hu12 Block of Hu Zhuangji oil field is a highly heterogeneous reservoir. At present the water cut in this block is quite high while the recovery rate is still low after waterflooding more than a decade, which means that there is much oil remaining in place. In order to get more oil from this block, we employed a couple of ways such as Lab experiments, correlations from home and abroad and field data to predict the final recovery rate. According to our research results, we can enhance the potential oil production by improving the sweeping efficiency of waterflooding. We also suggest that many conventional ways such as grouping smaller layers, changing the well pattern in some area, controlling profile and applying EOR should be used to improve recovery rate.
