摘　　要：低渗透非均质稠油油藏,天然能量差,常规蒸汽吞吐工艺管柱复杂且周期采油量低,油气比、回采水率低,有效期短,采用氮气辅助蒸汽吞吐工艺可以简化工艺管柱,降低蒸汽注入量,提高周期产油量和回采收率。Due to the low permeability and low pressure in heterogeneous heavy oil reservoir, the process string for the conventional steam stimulation is complex, and periodic oil-producing rate is low, gas-oil ratio and back water production rate is low and effective period is short . But using the nitrogen-assisted steam stimulation technology can simplify the process string, reduce the steam injection rate, improve the periodic oil production and back oil recovery rate.
