Abstract
Vannbasert boreslamtilsetning omfattende en forblandet kombinasjon av ca. 2 deler uintaitt med høyt mykningspunkt, ca. 1 del uintaitt med lavere mykningspunkt, ca. 1 del kaustifisert lignitt og et sterkt lipofilt, ikke-ionisk tensid. Denne blanding reduserer leirskifersvellingen og ustabiliteten i borehullet under boring av brnner.Water-based drilling mud addition comprising a premixed combination of approx. 2 parts unintentionally with a high softening point, approx. 1 part unintentionally with lower softening point, approx. 1 part caustified lignite and a strong lipophilic, non-ionic surfactant. This mixture reduces clay shale swelling and instability in the borehole during drilling of wells.
