摘　　要：探索窄河道致密砂岩气藏效益开发高效井识别方法。通过调研与开发实践建立窄河道致密砂岩气藏气井产量预测模型,结合气藏开发经济评价理论,建立以单井等效内部收益率为核心的高效井识别方法与评价模型。实例分析表明,采用该方法能够更为有效地识别高效井,弥补了传统的以无阻流量为核心的产能评价体系的不足,进而为窄河道致密砂岩气藏效益开发气井产能评价、高效井识别提供了新思路和新方法,对明确高效井特征、气井部署以及开发方案的编制具有重要作用。Explore new technological methods for identifying efficient wells for benefit development for tight sandstone gas reservoir of narrow channel.Based on investigation and the practice of gas field,build the production prediction model of gas wells for tight sandstone gas reservoir of narrow channel,and combine it with the theory of economic evaluation of gas reservoir development to set up the ways of identifying efficient wells with the factor of internal rate of return.Examples show it is reliable to pick up efficient wells,which makes up the absolute open flow capacity of a gas well as the productivity evaluation criteria at present.So it is of importance for the identification of efficient wells,and it helps to make clear production characteristics of efficient wells,deploy gas wells and optimize development scheme of gas field.And it is a new way for improving profits for companies.
