Abstract

L'invention a trait à un fluide de forage à base d'eau, qui contient un latex polymère pouvant former un film de latex déformable sur au moins une partie d'une formation souterraine. Ledit fluide de forage permet de réduire la pénétration de pression lorsqu'il est utilisé pour forer des formations schisteuses dans le cadre d'opérations d'extraction d'hydrocarbures. On utilise de préférence, en conjonction avec le polymère, un agent de précipitation, tel qu'un silicate ou un complexe d'aluminium (par ex., de l'aluminate de sodium). En général, l'eau présente contient un sel permettant de former une saumure, souvent à saturation, bien que l'invention puisse être mise en oeuvre avec de l'eau douce. Si l'on emploie un sel, il est souvent utile de recourir également à un tensioactif, comme de la bétaïne.
