Abstract

In view of the problems of large heat consumption and low heat utilization rate in SAGD (Steam Assisted Gravity Drainage) development in mid-deep super-heavy oil reservoirs, the causes and influencing factors of heat loss in each phase of SAGD development were analyzed by referring to the actual production data of SAGD in Guan Tao reservoir, Du Block 84, Liao he Oilfield, and the heat loss in each phase of the whole development process was calculated. Measures to improve thermal efficiency are also proposed. The results show that the heat loss in the whole process of SAGD development includes 6 parts: steam boiler heat loss, steam separator heat loss, steam injection pipeline heat loss, steam injection wellbore heat loss, formation heat absorption and production wellbore heat loss. The heat loss is mainly concentrated in steam injection boiler, steam separator, steam injection pipeline and steam injection wellbore, the heat loss ratio reaches 34.8%, and the formation heat absorption ratio is only 36.0%. In view of the main heat loss phase, the strategies to improve the thermal efficiency were proposed, and the comprehensive thermal efficiency was increased by 17.0 percentage points after field implementation. This study can provide technical reference for improving SAGD development efficiency and economy in mid-deep super-heavy oil reservoirs.
