摘　　要：蒸汽吞吐是稠油开采的重要方法之一,曙光油田稠油产量的比例逐年增大,高轮次吞吐后,地层压力降低,地下存水增多,原油产量下降,以及油井套管变形或损坏数量增加,不能实施常规的封隔器隔热措施。采用增能助排技术,实现隔热补充能力及助排一体化,配合一次泵等辅助措施,为油田的经济有效开发开辟了新的技术保障。The cyclic steam stimulation is one of important methods of heavy oil exploitation, proportion ot 5huguang oilfield heavy oil output increases year by year. After high order cyclic steam stimulation, formation pressure decreases underground water storage increases, crude oil output declines, and the well casing deformation or damage increases in number, conventional packer heat insulation measures can not be implemented. Increasing formation energy and cleanup technology was used to realize the integration of heat insulation, energy supplement and cleanup. With primary pumps and other auxiliary measures, the technology can provide a new technical support for economic development oilfield.
