Well Interference Analysis of Shale Gas Wells Based on Embedded Discrete Fracture Model

Well interference is commonly observed in shale gas reservoirs due to the small well spacing, and it significantly affects production. Effective evaluation of important increase production wells. Previous researches mainly focus on phenomenon optimization using numerical simulation so that quantitative analysis rare. Therefore, this paper aimed at analyzing wells through type curves. First, complex fracture networks are described by embedded discrete model (EDFM). Second, different cases designed characterize types degrees reservoirs. Third, modelling conducted simulate its effect Fourth, curves obtained quantitatively analyze compare impact Results show caused hydraulic fractures reduce parent while child can be increased owing larger equivalent stimulated area. The pressure depletion obvious when communication degree becomes higher. Differences found from early late periods combination log-log Blasingame This work provides a method for evaluation, used obtain spacing adjust fracturing parameter
