摘　　要：下寺湾油田柴窑井区属于低压低渗透油藏,目的层位是长6油层,目前开发效果很好。但在长期开采过程中随着开采程度的增加,地层压力下降,溶解气析出,原油粘度增加,在不规范注水的情况下造成产量递减很快,因此,需加强注水,提高油井产量。Chaiyao well area of Xiasiwan oilfield belongs to the low pressure low permeability reservoir,and Chang 6 oil layer is its target reservoir which is developed well currently.But in the long term exploitation,with the mining process increasing,the formation pressure decreasing,dissolved gas precipitating,crude oil viscosity increasing,the oil production will decline quickly in the case of non-standard water injection,therefore,to strengthen water injection is needed to increase oil production.
