摘　　要：苏里格气田地质情况复杂，认识程度低，开发难度大，动储量的大小是制定合理开发方案的基础。为此，应用产量不稳定法计算了苏里格气田的动储量，该方法不需关井测压，也不必定压、定产生产，比压降法更加适用于初期开采的苏里格气田，并提出了按动储量进行气井分类的新标准，气井新的分类标准符合率达到了93．75％。通过将动储量与地震多参数响应结果对比分析，确定了Ⅰ、Ⅱ类井的地震油气检测评价标准，可用于井位优选及钻前早期动储量预测，为气田的有效开发提供了一种新技术方法。In Sulige Gas Field, due to complicated geological conditions, poor understanding of the gas field and high development difficulty, the dynamic reserves are the basis for reasonable development planning. The instable production calculation method is used to determine the dynamic reserves of Sulige Gas Field. With the application of this method, shut in pressure survey or constant pressure production and regulation production are not needed, and this method is more adaptable than drop method to Sulige Gas Field which is at the early production stage. A new standard of gas wells category based on dynamic reserves is proposed, and the coincidence rate of the new standard can reach 93.75%. Through comparative analysis of dynamic reserves and multi parameter seismic response characteristics, an evaluation standard for seismic hydrocarbon detection in type Ⅰ and type Ⅱ wells is established. The evaluation standard can be used for well site optimization and dynamic reserves prediction before drilling, and this is new technique for the effective development of gas fields.
