摘要
根据注汽过程中油管和油层流体相互联系的实际情况，提出了油管流动和油层渗流相互协调计算的数学模型，通过分析得到了一定注汽条件和油层特性下最大注汽流量的计算方法，为注汽方案的设计和油藏数值模拟流量的选择提供了依据，并进一步分析和计算了油井深度、油层特性及井口注汽压力对最大注汽流量的影响．研究表明，在油藏数值模拟和选择注汽方案时，注汽流量必须适宜，即与油层的吸汽能力相互协调．
During the steam injection to reservoir, the flows in wellbore and reservoir are connected each other. A model for calculating the flows in coordination fashion is presented. The maximum steam injection flow rate can be calculated by the use of this model. This method is useful in steam injection plan design and thermal numerical simulation. It is found that the well depth, the properties of oil reservoir and the pressure of well head have great effects on the maximum flow rate..
