摘　　要：为合理地开采DC构造下二叠统气藏,选取该构造生产史较长的DS1井、DS001–X1井,采用物质平衡法、现代产量递减分析法、生产史拟合法、产量累计法计算两井的动态储量。结果表明,两口井动态储量大,具有较大的开采潜力。所采用的计算方法计算过程相对简便,但产量累计法需在气藏开发到一定程度、气井产量发生连续递减后才可使用,目前物质平衡法、现代产量递减分析法及生产史拟合法计算的结果较为准确。In order to reasonably exploit the lower Permian gas reservoir of DC structure, DS1 and DS001–x1 wells with long production history are selected to calculate the dynamic reserves of the two wells by material balance method, modern production decline analysis method, production history fitting method and production accumulation method. The results show that the dynamic reserves of the two wells are large and have great exploitation potential. The calculation process of the methods is relatively simple, but the production accumulation method needs to be used after a certain degree of gas reservoir development and continuous decline of gas well production. At present, the results of the material balance method, the modern production decline analysis method and the production history fitting method are relatively accurate.
