RHEOLOGICAL CHARACTERISATION OF CRUDE OILFOR DRILLING AND PRODUCTION PETROLEUMAPPLICATION
Résumé
Crude oil is subjected to important variation in temperature during its extraction and transport in the pipelines, or when used in
oil based drilling fluids. These changes have a direct effect on the rheology of oil which conditions its transport or ensures a
good cleaning of the well as a drilling mud. According to these considerations, it is interesting to know how the rheological
properties of crude oil vary as a function of temperature over a relatively long period of time. This study has been conducted
on a sample of crude oil, which has been subsequently aged several months, the rheological behavior of oil was determined at a
temperature of 20 ° C by using a Rheometer ARES, then the viscosity temperature relationship was investigated for
temperatures of 20 °, 30 °, 40 °, 50 ° 60 ° and 80 ° C, and finally the activation energies of the two samples were calculated
Le pétrole brut est sujet à d’importantes variations de la température durant son extraction et son transport dans les pipelines,
ou pendant son utilisation dans les fluides de forage à base d’huile. Ces changements ont un effet direct sur la rhéologie de
l’huile qui conditionne le transport et assure un bon nettoyage du puits lorsqu’il est utilisé dans les compositions des boues de
forage. En tenant compte de ces considérations, il est intéressant de connaître comment varient les propriétés rhéologiques du
pétrole brut en fonction de la température sur une période relativement élevée. Cette étude a été faite sur un échantillon de
pétrole brut qui a été vieilli de quelques mois, le comportement rhéologique du pétrole a été déterminé à la température de 20
°C en utilisant le rhéomètre ARES , ensuite la relation viscosité-température a été étudiée pour les températures de 20 °, 30 °,
40 °, 50 ° 60 ° et 80 ° C , finalement les énergies d’activation des deux échantillons ont été calculées.
