Predicción de flujo multifásico en sistemas de recolección de crudo: descripción de requerimientos

Li, “A two-phase, two-component model for vertical upward gas-liquid annular flow,” International Journal of Heat and Fluid Flowvol. Multiphase Flow 18 3 Some examples of works in this period are [13],[14] and [8].

The Empirical Period, This information allows to assess different models in a wide range of situations. The Journal of Canadian Petroleum Technology. For each experimental point the hydrodynamic parameters were kept constant with time, namely: Characteristics tubetias the foam emulsion.

Other example of a drift flux model with tunning capabilities is presented in [41].

Raithby, “A transient two-fluid model for the simulation of slug flow in pipelines – i. An example of three methods to select flow pattern is shown in the Figure 1. An homogeneous model, a drift flux model and a segmented approach was used by [26] to calculate the pressure drop in a wellbore. A numerical analysis tuberas the two fluid model near ill posedness was made by [57]. Brennen, Fundamentals of Multiphase Flow. InBannwart et al. Ginestra, “A fully-coupled thermal multiphase wellbore flow model for use in reservoir simulation,” Journal of Petroleum Science and Engineeringvol.


Steady state models do not need a mass balance equation, also, properties are averaged in a piece mulfifasico the pipe, and the superficial velocities are calculated from a volumetric flux at standard conditions. Another study which investigated utilization of 2 was done by [36], as result of their work, they obtain other values to the distribution parameter and drift velocity as a function of void fraction, velocities, densities and inclination angle.

The size of the bubbles increases as coalescence progresses, 15 minutes later the shape of the bubbles mulfifasico the foam were mostly spherical, covered by a liquid film, with bubble size tuberiias the order of several millimeters and it was possible to differentiate two zones: Equally important, they described a flow pattern map with three main regions.

C assaniF. According to Shohamthe single-phase flow hydrodynamics systems are well understood, however, the simultaneous flow of two fluids is considerably more complex due to the presence of the gas and liquid phase.

Normally, this difference is negligible what was the assumption used by [54]. Froth flow is calculated as an interpolation of dispersed bubble flow and annular mist or slug flow and annular mist, this solves discontinuity problems caused by transitions between flow patterns. The Modeling Period, – They find first the void fraction with a representative liquid mixture and then, they calculate the holdup of every liquid.

Oilfield Chemistry in Chinese14, 4. Then in Figures 8d and 9d the coarsening effect is no longer present, only the collapse effect was visualized. For two-phase flow, it is necessary to consider operational variables as: Mukherjee, Multiphase flow multifwsico wells.

Regarding flow pattern, an example of a wrong selection of flow pattern at high pressure was given by [19], in which, annular flow is predicted when churn, slug and dispersed bubble flows are also possible. Also, some differences in the predicted flow pattern for high viscous flow was shown mkltifasico [63],[64] and [65].

Another values of C o and u D were presented by [39], see equation 4. The most complex methods for simulation of two phase flow not always imply the most accurate methods. The pressure correction schemes can cause convergence problems due to linkage between equations, some modifications for the SIMPLE method are explained by [48] to avoid some convergence problems.

No matter which kind is, all models get as their results the value of pressure drop per unit length and multidasico generally include the calculation of the holdup and flow pattern. In addition, some cases in which terrain slugging was unsatisfactorily predicted by Commercial software were presented by [67].
