| 摘 要： | 应用叠加原理建立了变流压条件下不稳定流量响应的数学模型。通过该模型可以建立压裂井产量递减资料的解释方法，该方法采用日常的生产记录产量与时间的资料进行地层参数解释。针对资料解释参数估计方面的困难，应用遗传算法(GA)优化途径，对压裂井产量生产动态资料进行解释，确定地层参数(渗透率、表皮系数、地层平均压力和井筒储存系数等参数)和损害程度。此方法为气田开发监测提供了更经济的途径。

| Abstract: | Applying the superposition principle,the transient rate's mathematics model under the variable flowing pressure condition has been introduced.The method's mechanism which use normal rate record and time data to interpret formation data has been presented. By the GA optimize route, the rate dynamic data of fracturing well can been interpreted and formation parameters and damage degree can been determined (including permeability,skin factor,average formation pressure and well bore storage factor) . The method is useful and economical to development inspection of gas reservoirs. |
