BORE: A Computer Program for the Analysis of Wellbore Heat Loss Associated with Steam Injection into Oil Reservoirs

摘要

The computer program BORE was developed for the analysis of wellbore heat loss associated with steam injection into oil reservoirs. The steam flow in the wellbore is assumed to be one-dimensional in the axial direction with quasi-steady heat transfer occurring only in the radial direction. Applications are restricted to cases for which the steam quality is between zero and one-hundred percent. The basic wellbore geometry treated consists of an insulated injection tube positioned concentrically within a casing and separated from the casing by an annular air gap. The casing is, in turn, surrounded by a layer of cement and is embedded in a formation which is infinite in extent. Steam quality, temperature, pressure, and enthalpy are computed as functions of depth for specified geometry, inlet flow conditions and thermophysical properties. 20 refs., 3 figs., 1 tab.
