Item type:Article, Access status: Open Access , Badania wpływu nowo opracowanych płuczek kationowo-skrobiowych na zmianę przepuszczalności ośrodka przy użyciu filtrów ceramicznych(2007) Wysocki, Sławomir; Bielewicz, Danuta; Wysocka, MartaIn this paper results of investigations of new drill-in muds with cationic polymers are presented. Rheological properties and influence onto permeability of rocks were research. Investigations were moved in simulated downhole conditions. In tests dynamic HPHT filter press and ceramic filters (as a rock simulator) were used. Research shoved, that new cationic-starch drill-in muds couse smaller permeability damage than mud used in Polish industry.
