Resumen:

In this paper a lumped-parameter model of transient twophase gas-liquid flow in a wellbore was developed. The model is based on the assumption that the flow process is essentially one-dimensional so that area-average properties can be represented as function of one space variable and time. The wellbore is divided into a number of control volumes (nodes) that are connected by junctions (flow paths). Mass and energy equations are applied to each control volume and an approximate momentum equation is used to calculate flow rate at each junction. A numerical algorithm for coupling the wellbore model with a reservoir model is proposed. Calculations were carried out to determine the behavior of the wellbore flow during a pressure buildup test. The results obtained from this calculations were compared to theoretical results found in prior literature. © 1997, Society of Petroleum Engineers, Inc.
