A Coupled Well Bore-Reservoir Production Investigation for Fractured Horizontal Wells

Abstract:

Considering the reservoir seepage, borehole wall inflow, fracture and perforation flow’s process and mutual influence, an unsteady state computation model of fractured horizontal well coupling with reservoir was established based on the source function and superposition principle. Calculation results showed that compared to the production only from the hydraulic fractures, the difference of that both from fractures and perforations was great early and decreased slowly later. Take the perforation production for example, because of mutual interference and well bore flow friction, different location perforations with different output and the central-perforation production was lower than that of the outer-position.
