摘　　要：搞清油藏的流体分布及其储量动用状况等，是改善注水开发效果进行开发方案研究的前提。该文利用数值模拟方法，在对永安３－２断块将近３０年开采历史进行历史拟合的基础上，得到了剩余储量及剩余油分布等，明确了开发潜力所在，并着重研究了细分层系、调整注采关系和加密调整对未来开发动态的影响。数模预测结果表明：①细分层系后，减少了层间干扰，提高了注水效果；②主力油层通过调整注采关系，抽稀井点生产，同样可以延长稳产期，并能达到提液增油的目的；③非主力油层通过调整注采关系和加密调整，增油效果显著；④该研究对整个永安３断块的后期开发调整具有一定的指导意义。It is necessary that having good knowledge of reservoir fluid distribution and reserves production status in order to improve development effectiveness of waterflooding and study development program. By use of numerical simulation and on the basis of history match of the 30 years production history of fault block Yongan 3 2, the remaining reserves, the current oil distribution; where the development potential is; have been obtained and studies emphasizely the effect of subdividing series of strata, adjusting injection production relation and infill adjustment on future development performance. The predicted results show that (a) the interlayer interference has reduced and water injection effectiveness enhanced after the series of strata were subdivided; (b) through adjusting injection production relation of major production formation and producing by sparse well points, the stable production period can be also prolonged and oil production increased; (c) through adjusting the injection production relation of the non major reservoirs and infill adjustment, oil production can be improved obviously and (d) this research is of certain guiding significance to the later period development and the adjustment of the whole fault block Yongan 3.
