Venturi Wet Gas Flow Modeling Based on Homogeneous and Separated Flow Theory
When Venturi meters are used in wet gas, the measured differential pressure is higher than it would be in gas phases flowing alone. This phenomenon is called over-reading. Eight famous over-reading correlations have been studied by many researchers under lowand high-pressure conditions, the conclusion is separated flow model and homogeneous flow model performing well both under high and low pre...
متن کاملExperimental and Theoretical Study of the Gas-water Two Phase Flow through a Conductance Multiphase Venturi Meter in Vertical Annular (wet Gas) Flow
Annular gas-liquid two phase flow is widely encountered in the nuclear industry. Various combinations of techniques have been employed in annular gas-liquid two phase flows to measure the flow parameters (e.g. liquid film thickness, gas volume fraction and the phase flow rates). One of the most useful techniques which has proven attractive for many multiphase flow applications is the electrical...
متن کاملEvolution of Wet Gas Venturi Metering and Wet Gas Correction Algorithms
The Venturi meter is a straightforward pipeline device used for the metering of gas and liquids. This article presents a brief summary of the creation and characterisation of the modern Venturi meter, including the historic development of public domain algorithms to derive two phase (gas and liquid) flow rates from differential pressure measurements. The use of Venturi meters in multiphase oil ...
متن کاملModeling Critical Flow through Choke for a Gas-condensate Reservoir Based on Drill Stem Test Data
Gas-condensate reservoirs contain hydrocarbon fluids with characteristics between oil and gas reservoirs and a high gas-liquid ratio. Due to the large gas-liquid ratio, wellhead choke calculations using the empirical equations such as Gilbert may contain considerable error. In this study, using drill stem test (DST) data of a gas-condensate reservoir, coefficients of Gilbert equation was modifi...
متن کاملModel-based drilling fluid flow rate estimation using Venturi flume
Monitoring the flow rate out of the well is critical for good control of the downhole pressure in drilling operations. In this feasibility study, we explore the possibility of using a Venturi flume to provide a cost-effective measurement of the flow rate, with improved accuracy compared to conventional methods. A Venturi flume has been simulated both using CFD and a simplified 1D model. By prop...
