The purpose of this research is to improve the recovery of heavy oil and bitumen by the simultaneous injection of chemicals with down-hole generated steam in oil sand reservoirs. Two types of down-hole steam gene-rating units are designed and constructed. One is a gas burner type and was designed to generate 5-10 kg/hr. Of steam under a working pressure of 15 kg/cm^2. The total length of the generator is 1m and its diameter is 125mm. Fuel gas was initially mixed with air in order to maintain a stable combus-tion in the burner. The inlet water was pre-heated by waste flue gas and then injected into the heat exchange columns.The burner type generator produced 94.8% of dry steam and exhibited a heat exchange efficiency of 66%.the other one is an internal electrical heater which was constructed by seathed wire and metal casted heater. This type of heater was capable of producing 93.6% dry steam with a heat exchange efficiency of 70%.

本研究的目的是通过在油砂油藏井下生蒸汽中同时注入化学剂，提高稠油和沥青的采收率。设计并建造了两种井下蒸汽分级装置。一种是燃气燃烧器类型，设计为产生5-10公斤/小时。在工作压力为15kg /cm^2的情况下。发电机全长1m，直径125mm。燃料气体最初与空气混合是为了在燃烧器中保持稳定的燃烧。进水经废烟气预热后注入换热塔。燃烧器式发生器的干蒸汽产出率为94.8%，热交换效率为66%。另一种是内嵌式电加热器，由钢丝和金属铸造加热器构成。该型加热器能产生93.6%的干蒸汽，热交换效率为70%。
