The calculating method and application of economic limiting steam/oil ratio for steam flood and steam soak.

Under the given technical and economic conditions, the steam oil ratio at the balance between the output value after taxation and the cost for ton oil of heavy oil field developed under steam flooding is the economic limit steam oil ratio under this condition. It mainly relates to oil price and direct operation cost. Under the circumstances of fixed commodity tax, ton oil tax and value added tax, 4 main technical and economic parameters, such as oil consumption of steam, utilization ratio, operation cost of ton oil and sale price of ton oil have an effect on the calculation results of economic limit steam oil ratio. Economic recoverable reserve is an important index for evaluation and decision, which mainly relates to economic limit steam oil ratio and the law of the change of oil production.
