Abstract

Описывается способ формирования подземной скважины и способ снижения фильтрации (водоотдачи) в скважине во время бурения подземной скважины. Способы включают использование многокомпонентного волокна как материала для борьбы с поглощением. Многокомпонентное волокно, внешняя поверхность которого включает, по меньшей мере, первую полимерную композицию и вторую полимерную композицию. По крайней мере, часть внешней поверхности многокомпонентного волокна включает первую полимерную композицию, которая, как минимум, частично адгезивно формирует фильтрационную корку из бурового раствора, используемого в данном способе.
