摘　　要：目前,致密砂岩气藏分段压裂水平井产能预测面临拟合率不高、EUR预测不准,以及对生产数据依赖性强等问题。根据致密砂岩气藏分段压裂水平井渗流特点,以经典的Arps递减为基础,采用分段方法预测其产能。结合现场数据,对此方法进行分析验证,提出了适合致密砂岩气藏分段压裂水平井的产能递减方程,达到了在生产数据较少的条件下准确预测分段压裂水平井产能及EUR的目的,得到致密砂岩气藏分段压裂水平井产能预测方法,为评价致密砂岩气藏单井产能和开发方案编制提供了依据。To problems of the lower fitting rate,inaccurate on the forecast of EUR and the highly dependence to the production data that faced multistage fracturing to horizontal well in tight sandstone gas reservoirs at present,using the seepage characteristics of the multistage fracturing horizontal well in tight gas reservoir,taking the classics Arps decline as the basic,utilizing the segmental method to forecast the production capacity and combining with the real field data to analyze and verify the new method,production capacity decline equation that fits for the multistage fracturing horizontal well in tight gas reservoir has been proposed,an accurate prediction of the production capacity and EUR with the multistage fracturing horizontal well in tight gas reservoir under the conditions of few production data is achieved,the forecast method of production capacity decline is got,which provides a basis for evaluating production capacity of the single well and establishing development program.
