description | Among the methods provided is a method of drilling a subterranean well with an invert emulsion fluid comprising: providing an invert emulsion fluid formed by combining components that comprise: an oil-based continuous phase; an aqueous discontinuous phase; and a polar hydrophobic additive that comprises a polar hydrophobe, wherein the polar hydrophobic additive may substantially increases the yield point, the low-shear yield point, or both of the invert emulsion fluid relative to a fluid without a polar hydrophobic additive while limiting the change in the plastic viscosity to no more than about 35% of the change in the property with the largest increase; and placing the invert emulsion fluid in a subterranean formation.
Parmi les procédés de l'invention se trouve un procédé de forage d'un puits souterrain avec un fluide en émulsion inverse comprenant : la fourniture d'un fluide en émulsion inverse formé par combinaison de composants qui comprennent : une phase continue à base d'huile ; une phase aqueuse discontinue ; et un additif polaire hydrophobe qui comprend un hydrophobe polaire, l'additif hydrophobe polaire pouvant augmenter considérablement la limite apparente d'élasticité, la limite apparente d'élasticité à faible cisaillement, ou les deux, du fluide en émulsion inverse par rapport à un fluide sans additif hydrophobe polaire, tout en limitant la variation de viscosité plastique à une valeur inférieure ou égale à environ 35 % de variation de la propriété avec la plus grande augmentation ; et le placement du fluide en émulsion inverse dans une formation souterraine. |
