Time-Varying Sequence Analysis of Generalized Vogel Equation for Fracturing Wells in Fractured Volcanic Reservoirs

doi:10.7657/XJPG20190308

Abstract

Abstract: From the non-dimensional typical chart of bottom hole pressure during fracturing, combining with the generalized Vogel equation for fractured reservoirs, the article establishes a solving method of the inflow performance curves with different producing days in fractured reservoir fracturing wells. The reliability of the research results are verified by an example and the variations of the inflow performance curves with different producing days and different non-dimensional fracture conductivity are analyzed. The results show that when the non-dimensional fracture conductivity is large, the initial well production is high but the production decline is large and it is difficult to maintain the well production. Therefore, selecting a reasonable non-dimensional fracture conductivity value has practical significance for efficient development of fractured volcanic reservoirs
