摘　　要：经济极限油汽比对蒸汽吞吐开发油田具有重要的经济意义,目前行业标准和国家标准并没有给出蒸汽吞吐开发油田的单井经济极限油汽比的具体计算方法。基于投入产出平衡原理,按照相关因素法确定操作成本,推导得出蒸汽吞吐开发油田单井经济极限油汽比计算模型。以辽河油田区块A为例,计算不同油价、不同单井日产油下的单井经济极限油汽比,绘制相应图版。结果显示,产油量为2.5吨/日,油价90美元/桶时,单井经济极限油汽比为0.0823,目前油汽比仍大于单井经济极限油汽比,该井依然具有一定的经济效益,仍处于效益开发阶段。The economic limit steam-oil ratio is of great economic significance for oilfield developed by steam stimulation.The current industry and national standards do not give a specific calculation method for the economic limit steam-oil ratio of single well.Based on the principle of input-output balance,this paper determines operating cost according to the relevant factor method and derives a model for calculating the economic limit steam-oil ratio of single well in heavy oil reservoir developed by steam stimulation.Taking Block A in Liaohe oilfield as an example,it calculates economic limit steam-oil ratio of single well under different oil prices and different daily oil production of single well,and draws corresponding charts.The results show that the economic limit steam-oil ratio of single well is 0.0823 when the oil production is 2.5 tons/day and the oil price is USs90/barrel.The current steam-oil ratio is still greater than the economic limit steam-oil ratio of single well and therefore the well still has certain economic benefits as well as still at the stage of effective development.
