PSEUDO-STEADY-STATE PRODUCTIVITY FORMULA FOR A PARTIALLY PENETRATING VERTICAL WELL IN A CIRCULAR CYLINDER RESERVOIR
Краткое описание
For a bounded reservoir with no-flow boundaries, the pseudo-steady-state flow regime is common at long production times. Taking a partially penetrating vertical well as a uniform line sink in three dimensional space, by the solving three-dimensional diffusivity equation and developing necessary mathematical analysis, this paper provides the step-by-step derivations of a pseudo-steady-state productivity formula for an off-center partially penetrating vertical well arbitrarily located in a closed circular-cylinder-drainage volume, using a uniform line sink model. This paper also presents a formula for calculating a pseudo skin factor due to partial penetration, and a formula for calculating the shape factor of an isotropic circular reservoir with a fully penetrating vertical well arbitrarily located within the reservoir.
