Develoment and applicationof a wellbore/reservoir simulator for testing oil wells

摘要

A comprehensive coupled wellbore/reservoir simulator has been developed to study the behavior of single-phase oil flow in the wellbore. The wellbore is modeled numerically in which mass, momentum, and energy of the fluid are conserved, while the reservoir fluid flow is treated analytically. Energy transport occurs through the tubular, cement sheaths, and the formation by conduction. However, both conductive and convective heat transport mechanisms are operative for the annular fluid. Heat losses through seawater and air are also modeled for a well producing in an offshore environment.
