Abstract
The well plant operation mode with high integration degree is widely adopted for shale gas reservoir development. In order to study the production dynamics of fractured horizontal wells in staggered placement mode, multiple seepage mechanisms of shale gas at the microscopic scale are considered, and a reservoir-fracture-wellbore coupled point source function flow model is developed based on the pressure drop superposition principle to investigate the factors influencing the production capacity of fractured horizontal wells in staggered placement mode. The study shows that not considering the microscopic seepage mechanism will overestimate the production of shale gas fractured horizontal wells, in which viscous flow makes the largest contribution to gas flow; the larger the overlap area of adjacent gas well modifications, the smaller the gas well production, and the decreasing production increases with the increase of the overlap area, so shale gas production platforms should avoid the overlap of modifications between adjacent wells; with the increase of well spacing, the gas well production increases, but the increase gradually decreases. The optimal well spacing exists between platform production wells. The study considers the microscopic seepage mechanism of shale gas and combines the fractured horizontal well capacity model to realize the study of the capacity dynamics of staggered fractured horizontal wells, which provides a reference for the study of multi-well production capacity.
