摘　　要：压力梯度是气举井设计的基本依据,是影响气举井设计和运行的重要参数。文章在综述垂直管内石油气液两相流的压力梯度研究方法的基础上,利用奥齐思泽斯基计算方法对我国轮南油田气举井气液两相流的流压进行了分析计算。计算结果表明,所采用的计算方法适用于轮南油田气举井的流压梯度预测。The pressure gradient,as one of the most important parameters affecting design and operation of gas-lift wells,is the foundation of gas-lift well design.Based on summarizing the investigations of gas-liquid pressure gradient in vertical tubing,the paper analyzes and calculates gas-liquid flowing pressure in gas-lift wells in Lunnan Oilfield by Orkiszwski method.The results show that the calculation menthod is applicable to flowing pressure gradient prediction of gas-lift wells in Lunnan Oilfield.
