| 摘 要： | 为了掌握页岩气藏生产动态特征,提高页岩气井产能,对页岩气藏渗流机理及产能评价进行研究.页岩气藏与常规气藏最主要的差异在于页岩气藏存在吸附解吸特性.利用Lang-muir等温吸附方程描述页岩气的吸附解吸现象,点源函数及质量守恒法,结合页岩气渗流特征建立双重介质压裂井渗流数学模型,通过数值反演及计算机编程绘制了产能递减曲线图版.分析了Langmuir体积、Langmuir压力、弹性储容比、窜流系数、边界、裂缝长度等因素对页岩气井产能的影响.

| Abstract: | To know the dynamic characteristics of shale gas reservoirs' production and to improve shale gas wells production,it is very important to research on shale gas seepage mechanism and production evaluation.The main difference between shale gas reservoir and conventional gas reservoir is that shale gas reservoir has the adsorption and desorption characteristics.Combined with shale gas seepage characteristics,using point source function,the mass conservation law and Langmuir isotherm equation to describe the sh... |
