摘要
弹性能量指数可体现气藏的固有性质，在气田开发过程中表现出规律性的变化。通过分析不同类型气藏弹性能量指数曲线的变化规律，对不同类型气藏的开发阶段进行了划分，并结合实例进行了应用。应用结果表明，该气藏开发阶段划分方法科学、简便，具有较强的合理性与可操作性，为气田开发阶段的划分提供了一种新思路，并对深入认识气藏生命周期具有重要意义。
Abstract
The elastic energy index shows the intrinsic properties of gas reservoirs and varies following some laws in the development process of gas fields. Based on the study on the changing laws of elastic energy index curve for different types of gas fields, the development stages of gas fields were divided. The demarcation method was applied combining with the instances. The application indicates that the method is scientific, simple and has strong rationality and operability, which provides a new thinking to divide the development stages of gas fields and has great significance for deeply understanding the life circle of gas fields.
