Shale gas seepage mechanism and fractured wells' production evaluation
摘要
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 shale gas adsorption and desorption phenomena, it establishes dual media shale fracturing wells' seepage model. By the numerical inversion and computer programming, it draws production decline curve charts and analysises the Langmuir volume, Langmuir pressure, elastic storativity ratio, cross flow coefficient, borders, fracture length and other factors on the impact of shale gas wells production.关键词
