供油方式是发动机的工作需要燃烧混合气做功，而将燃料与进入发动机的空气混合的方式。
有效的方法是采用高位燃油箱供油方式，但如何保持其油面恒定是实际操作中的一个难题。
In order to meet this requirement, to adopt the fuel-supplying mode of a high-positioned fuel tank is an effective measure, but to keep the constant fuel level is difficult in operation.
通过已知油气藏的分析，冀中地区第三系碎屑岩油气藏的供油方式有两种：一是断面供油；
There are two kinds of oil supply ways in the Tertiary clastic rock oil reservoirs in Jizhong Region:one is fractured surface supply oil;
在相同供油量情况下，新供油方式形成环状流需要的入口气相速度低，且气速增大时一般不会形成夹带液滴，能够实现较好的环状流流型。
Results show that with the same oil amount, the new oil supply style needs a lower gas velocity in the inlet to shape the annular flow, and the oil drops will not appear in air flow.
