摘要
采用常规气藏递减分析方法(指数、双曲、调和)无法对火山岩气藏的动态进行分析,因此开展单井动态分析尤为重要。提出基于流动物质平衡的火山岩气藏单井动态分析方法,并引入Blasingame分析曲线来识别气井的流动阶段特征段,提高参数估算的可靠性。利用该方法对火山岩气藏气井生产动态资料进行分析和计算,得到气井的地层渗透率、地层损害表皮系数以及动态储量等气藏开发需要的关键参数,这些参数对指导气藏开发具有重要意义。
Critical anisotropy that exists in volcanic gas reservoir leads to great variances of single well controlled reserves and single well performance.Because normal gas reservoir decline analysis doesn＇t work well any more in volcanic gas reservoir, new gas well performance analysis method based on flowing material balance is presented with single well as the object for the special reservoir attribute in volcanic gas reservoir.Furthermore, Blasingame curve is suggested to diagnose different flow period and enhance the accuracy of parameter estimating.Reservoir permeability, format pressure,wellbore skin factor and dynamic reserve volume can be obtained with the new performance analysis method, which is significant for developing volcanic gas reservoir.
