摘　　要：为保障涪陵页岩气田产能建设,做好气井产能接替,需明确页岩剩余气储量动用程度。采用双孔双渗模型,通过结合气井井史数据,利用实际压裂参数和微地震数据建立人工裂缝模型,保证模型的精细刻画,综合得到页岩气分段压裂水平井数值模型,从而预测剩余气储量动用程度。研究结果表明,随着气井生产时间逐渐增加,压降漏斗波及范围越来越大,波及范围在人工裂缝波及范围往外延伸60m左右。To ensure the capacity building of the Fuling shale gas field and facilitate the replacement of gas well production capacity,it is necessary to determine the extent of remaining gas reserves that can be utilized.A dual-porosity dual-permeability model was adopted,and an artificial fracture model was established by combining well history data,actual fracturing parameters,and microseismic data to ensure the model's fine characterization.This integrated approach resulted in a numerical model for shale gas horizontal wells with staged fracturing,which was then used to predict the extent of remaining gas reserves that can be utilized.The study results show that as the gas well production time increases,the area affected by pressure drop(pressure drawdown funnel)expands,with the affected area extending approximately 60 meters beyond the reach of the artificial fracture.
