Frictional Pressure Drop for Gas–Liquid Two-Phase Flow in Coiled Tubing
نویسندگان
چکیده
Coiled tubing (CT) is widely used in drilling, workover, completion, fracturing and stimulation the field of oil gas exploration development. During CT operation, will present a gas–liquid two-phase flow state. The prediction frictional pressure drop for fluid tube an important part hydraulic design, its accuracy directly affects success technique. In this study, we analyzed effects void fraction, curvature ratio inlet velocity on CT, numerically. Experimental data verified simulated results. Flow friction sensitivity analysis shows reaches peak at fraction 0.8. gradient increases with increase ratio. As strength secondary velocity, increased trend aggravated. correlation factor coiled developed by regression simulation research results can support high quality hydraulics through which operations be guaranteed.

Two Phase Flow Pressure Drop Calculation Using Homogeneous Equilibrium Model
Although two-phase flow is frequently encountered in various location of the process plants, there is no a general accepted and verified two-phase flow model that may be used to size lines for such conditions. An obvious example is condensate water return lines. The API method that used in this study is based on the homogeneous equilibrium flow assumption, that is, equal velocity and equal temp...

This paper is a part of a recent series of studies by the authors to develop universal predictive tools for pressure drop and heat transfer coefficient for mini/micro-channel flows that are capable of tackling fluids with drastically different thermophysical properties and very broad ranges of all geometrical and flow parameters of practical interest. In this study, a new technique is proposed ...

In this paper, the problem of turbulent forced convection flow of water- alumina nanofluid in a uniformly heated pipe has been thoroughly investigated. In numerical study, single and two-phase models have been used. In single-phase modeling of nanofluid, thermal and flow properties of nanofluid have been considered to be dependent on temperature and volume fraction. Effects of volume fraction a...
متن کاملTwo-phase Pressure Drop during Flow Boiling of Hydrocarbon Fluids
The paper reports pressure drop data for hydrocarbon fluids boiling in vertical upflow in a 8.68 m long, 25.4 mm i.d. tube, heated by direct electrical heating. These data were recorded simultaneously with the boiling heat transfer measurements. The systematic trends of the measured pressure gradient with respect to vapour quality, mass flux and pressure are examined. This provides useful infor...
متن کاملTwo Phase Frictional Pressure Drop of Carbon Dioxide in Horizontal Micro Tubes
Two-phase frictional pressure drop data were obtained for condensation of carbon dioxide in single horizontal micro tube of inner diameter ranged from 0.6 mm up to 1.6 mm over mass flow rates from 2.5*10 to 17*10 kg/s and vapor qualities from 0.0 to 1.0. The inlet condensing pressure is changed from 33.5 to 45 bars. The saturation temperature ranged from -1.5 C up to 10 C. These data have then ...
