Steady State Productivity Equations for a Vertical Well in Anisotropic Sector Fault, Channel, and Rectangular Reservoirs

摘要: This paper presents steady state productivity equations for a fully penetrating vertical well in the following three anisotropic systems: (a) sector fault, (b) channel, and (c) rectangular reservoir using uniform line sink model. The new equations, which are based on conformal mapping method, simple, accurate, easy to use field practice. If is fault reservoir, function of angle sector, wellbore location angle, off-vertex distance, drainage radius. channel with two parallel impermeable lateral boundaries, flow rate reaches maximum value when located middle width. constant pressure equation provided calculate arbitrarily case where an off-center bigger than that centered well. It concluded that, well, different should be used geometries. DOI: 10.1115/1.3066429
