Previous issue date: 2009-09-29 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior, CAPES, Brasil. / The need for technological advances in the operation of drilling wells for oil has encouraged
the research and development of drilling fluids, like the study of the its flowing in different
geometries. On this work is studied the flow of two drilling fluids in pipe and annular tube
with the objective to evaluate rheological models that describe the fluid behavior, to
characterize the flow regimes using the experimental method and compare with correlations
found in literature, to evaluate equations of hydraulic diameter found in the literature, to
evaluate correlations of friction factor in the turbulent regime and to propose new correlations
for the friction factor in turbulent regime. The data are obtained in a pilot plant consisting of a
system operating in closed circuit of 6 meters composed of horizontal tubes made of
galvanized iron, arranged in three parallel lines of independent flows that allow the
measurement of friction loss caused by a circular tube of 1" of diameter and by two ratios of
concentric annular tubes (annulus formed by 2" and 3/4 "and 1 1/4" and 1/2"). The system
consists of a tank with a capacity of 500 liters, with a mechanical stirrer, connected to a
positive displacement pump of helical type with 25HP, operating with volumetric flow up to
20m3/h. The pilot plant is instrumented with a set of three transducers of pressure. The
rheology of the fluid is evaluated with the aid of a FANN viscometer, model 35A. The
rheological models used are the power law and Casson. The results show that the choice of
equations of hydraulic diameter and friction factor are dependent on the geometry of flow and
the rheological model used, showing that should be analyzed separately. The new correlations
of friction factor for turbulent regime generate good results. / A necessidade de avan?os tecnol?gicos na opera??o de perfura??o de po?os de
petr?leo tem incentivado a pesquisa e o desenvolvimento de fluidos de perfura??o, assim
como o estudo do escoamento dos mesmos em geometrias distintas. Neste trabalho ? estudado
o escoamento de dois fluidos de perfura??o em tubos e dutos anulares, com o objetivo de
avaliar modelos reol?gicos que descrevam o comportamento do fluido, caracterizar os
regimes de escoamento utilizando m?todo experimental e comparar com correla??es
encontradas na literatura, avaliar equa??es de di?metro hidr?ulico encontradas na literatura,
avaliar correla??es de fator de atrito no regime turbulento e propor novas correla??es para o
fator de atrito no regime turbulento. Os dados s?o obtidos em uma unidade piloto constitu?da
de um sistema operando em circuito fechado de 6 metros de extens?o horizontal composto de
tubos de ferro galvanizado, dispostos em tr?s linhas paralelas de escoamento independentes
que permitem a avalia??o da perda de carga ocasionada em um tubo circular de 1" de
di?metro e em duas raz?es de anulares conc?ntricos (?nulo formado pelos tubos de 2" e 3/4",
e 1 1/4" e ?"). O sistema ? composto de um tanque com capacidade de 500 litros, dotado de
um agitador mec?nico, conectado a uma bomba de deslocamento positivo do tipo helicoidal
de 25HP, operando com vaz?es de at? 20m3/h. A unidade piloto ? instrumentada com um
conjunto de tr?s transdutores de press?o. A reologia do fluido ? avaliada com o aux?lio de um
viscos?metro FANN, modelo 35A. Os modelos reol?gicos adotados s?o o da pot?ncia e
Casson. Os resultados revelam que a escolha das equa??es de di?metro hidr?ulico e fator de
atrito s?o dependentes da geometria do escoamento e do modelo reol?gico utilizado, devendo
ser analisados separadamente. As novas correla??es de fator de atrito para o regime turbulento
geram bons resultados.
