摘　　要：雁木西油田第三系油藏水驱控制程度和水驱动用程度均比较好,但由于注水结构不合理导致注水利用率低、平面水驱状况不均衡。根据第三系油藏存在问题,确定了考虑气体亏空时的平衡注采比和不同注采比下的地层压力恢复速度,并进一步确定不同井组合理的注采比范围,制定了下步技术对策,为油田注采调整、挖掘剩余油指明方向。The study of this subject shows that control degree and producing degree of waterflood are better,but affusion utilizing ratio is low and planar water-flooding status is disproportion because of inconsequential injection structure.Production of some oil wells is better because of good water-flooding status and production of some oil wells is descending because of inconsequential working system.According to the problems of Tertiary reservoirs,the balanceable injection production ratio and pressure comeback rate are made certain using the related formulas,and the range of reasonable injection-production ratio is established in each injection compages.Next technology countermeasure and adjusting direction are put forward according to Tertiary reservoirs,which designate the direction of empoldering remaining oil and adjusting structure of injection-production.
