一种用于稠油油藏的多元热流体生产工艺以及热采工艺
摘要：
本发明涉及用于稠油油藏的多元热流体的生产工艺以及热采工艺，所述多元热流体生产工艺包括如下步骤：分别生产水蒸汽、二氧化碳、氮气，然后将所产生的水蒸汽、二氧化碳、氮气按如下体积百分比混合成多元热流体：水蒸汽40％-90％、二氧化碳0-30％、氮气0-30％。这种多元热流体生产工艺具有工艺简单、方便灵活的特点，多元热流体的组成可以在很大范围内调整，同时还能优化注入工艺。
摘要（英）：

The invention relates to a multi-element thermal fluid production process for a heavy oil reservoir and a thermal recovery process. The multi-element thermal fluid production process includes the steps: respectively producing water vapor, carbon dioxide and nitrogen; and then mixing, in volume percent, 40%-90% of the produced water vapor, 0-30% of the produced carbon dioxide and 0-30% of the produced nitrogen into multi-element thermal fluids. The multi-element thermal fluid production process has the advantages of simplicity, convenience and flexibility, components of the multi-element thermal fluids can be adjusted within a wide range, and an injection process can be optimized.
