    摘要: An invert emulsion wellbore fluid may include an oleaginous external phase; a non-oleaginous internal phase, wherein a ratio of the oleaginous external phase and non-oleaginous internal phase is less than 50:50; and an emulsifier stabilizing the oleaginous external phase and the non-oleaginous internal phase, wherein an average diameter of the non-oleaginous internal phase ranges from 0.5 to 5 microns.
