Determinación de calidad y flujo másico de vapor en la cara de formación mediante el uso de conformance de flujo crítico

The thermal processes supply energy in the form of heat to the reservoir, among them are steam injection, combustion in situ and hot water injection. The heat received by the reservoir in the steam injection processes has always been considered as an uncertainty, since this is dependent on the properties of the steam and the heat losses through the completion. By determining the properties, quality and mass flow just before entering the formation, the uncertainty of heat supplied between the injection and annular piping is reduced. A methodology is proposed and developed, the quality, through completion information, injection records and steam tables, density, mass flow and steam quality are determined throughout the well session. This methodology is based on experiments carried out on surface facilities, which by reducing the diameter of orifice plates and shock valves, generated a flow in a critical state. To expedite the definition of properties, the proposed methodology is mechanized, it was proposed to present in a template in Excel and later it was combined with the Visual Basic programming language. When evaluating the method at well conditions, steam quality profiles, density profiles and energy supplied in each sand are determined. Considerable losses of energy were observed, these being approximately 127MMBTUD, mostly attributed to completion. It is concluded that the heat injected has a greater dependence on mass flow than on steam quality.
