摘　　要：定量评价气举井效率是进行气举方案设计的基础,而目前气举井效率定量评价模型的相关研究较少。通过调研比较2种气举井效率定量评价方法并分析气举井的投入与产出,建立了新的气举井效率定量评价模型。新模型中涉及的参数简单易得,其中的标准参数可以结合油田生产情况进行调整,更能反映不同油田的生产状态,有利于现场应用。利用新模型计算了让纳若尔油田气举井效率,分析了该油田效率影响因素。研究成果丰富完善了气举井效率定量评价方法,对气举井方案设计、优化施工等提供了理论基础。Quantitative evaluation of the gas-lift well efficiency is the basis of the gas lift scheme design,while at present,the corresponding study of the quantitative evaluating model is rather few.By means of the investigation and comparison of two kinds of the quantitative evaluating methods of gas-lift wells efficiency,the input-output ratios of the gas lift wells were analyzed,and a new quantitative evaluating model of the gas-lift well efficiency was established.The related parameters are simple and convenient to obtain for the new model,among them,the standard parameters can be adjusted according to the production situation of the oilfield,so it can better reflect the production states of different oilfields and r is beneficial to the field application.With the help of the new model,the efficiencies of the gas-lift wells in Narwhal Oilfield were calculated and moreover the influencing factors of the efficiency in the oilfield were analyzed.The research results have enriched and improved the quantitative evaluation method of the gas-lift well efficiency,and furthermore have provided the bases for the scheme design of the gas-lift well,the optimization of the operation and so on.
