Abstract
Invasion of fluids into porous media during drilling can lead to irreparable damage and reduced well productivity. Hence, minimizing the filtration loss of the drilling fluid into the formation is very important. The stability of colloidal suspensions plays a crucial role in controlling the interfacial forces and consequently on minimizing the filtration. The zeta potential is an indicator of the stability of colloids with respect to their electrostatic interactions. In this study, the rheological properties of bentonite suspensions are investigated with and without additives. The starch and CMC were used as additives to enhance the rheological properties of bentonite. The effects of these additives on the drilling fluid filtration were examined. Zeta-potential, viscosity, gel strength and yield point were measured to characterize the extent to which control of the filtration loss of the drilling fluids can be achieved. The zeta-potential and the amount of filtration loss of water-bentonite suspensions were correlated. Finally, the results showed that the addition of either starch or carboxymethyl cellulose (CMC) enhances the filtration properties of water-bentonite suspensions.
Abstract
Das Eindringen von Flüssigkeiten in poröse Medien während des Bohrens kann zu irreparablen Schäden und verminderter Bohrlochproduktivität führen. Daher ist es sehr wichtig, die Filtrationsverlust der Bohrspülung in die Formation zu minimieren. Die Stabilität kolloidaler Suspensionen spielt eine entscheidende Rolle bei der Kontrolle der Grenzflächenkräfte und folglich bei der Minimierung der Filtration. Das Zeta-Potential ist ein Indikator für die Stabilität der Kolloide in Bezug auf ihre elektrostatischen Wechselwirkungen. In dieser Untersuchung werden die rheologischen Eigenschaften von Bentonitsuspensionen mit und ohne Zusatzstoffe untersucht. Als Additive wurden Stärke und CMC verwendet, um die rheologischen Eigenschaften von Bentonit zu verbessern. Die Auswirkungen dieser Additive auf die Filtration der Bohrspülung wurden untersucht. Das Zeta-Potential, die Viskosität, Gelstärke und Fließgrenze wurden gemessen, um zu festzustellen, wie stark der Filtrationsverlust der Bohrspülungen kontrolliert werden kann. Das Zeta-Potential und der Filtrationsverlust der Wasser-Bentonit-Suspensionen wurden korreliert. Schließlich zeigten die Ergebnisse, dass die Zugabe von Stärke oder Carboxymethylcellulose (CMC) die Filtrationseigenschaften von Wasser-Bentonit-Suspensionen verbessert.
