Abstract
Из многих композиций и способов, представленных здесь, один способ представляет собой способ предотвращения эмульгирования сырой нефти в жидкости для обработки на водной основе, который включает контакт сырой нефти в стволе скважины с жидкостью для обработки на водной основе, содержащей стирол-акрилатный сополимер, причем плотность сырой нефти в градусах АНИ (Американский нефтяной институт) составляет примерно 10 или более единиц; и предоставление возможности стирол-акрилатному сополимеру взаимодействовать с сырой нефтью в стволе скважины.Of the many compositions and methods presented herein, one method is a method for preventing emulsification of crude oil in a water-based treatment fluid, which comprises contacting the crude oil in the wellbore with a water-based treatment fluid containing a styrene-acrylate copolymer, wherein crude oil in degrees ANI (American Petroleum Institute) is approximately 10 or more units; and allowing the styrene-acrylate copolymer to interact with the crude oil in the wellbore.
