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 ,提高注水采收率 Hu twelve blocks belonging to a serious heterogeneous reservoir, after more than 10 years of water development, development is currently facing high water cut, low production problems. In order to improve the water injection and recovery rate of the block better, the water injection recovery rate of Hu12 was predicted by a variety of methods based on the laboratory test data, domestic and foreign empirical formulas and mine data. After the analysis and research, it is considered that: Hu twelve has the potential to improve water injection recovery, water injection should be to improve the volume and volume to do the work; and put forward Hu twelve block management to the use of subdivision stratification development, Local Wellbore injection and production of the relationship between the improvement of the profile control and the third layer of oil and other conventional methods to expand the water injection volume and increase injection recovery rate
