Fluid pills are commonly prepared for a variety of special functions, such as a sweep pill prepared at highviscosity to circulate around the wellbore and pick up debris or wellbore fill.
The supercritical fluid has the following unique characteristics: low viscosity, high density, better performance of flow, mass and heat transfer, dis solution and so on.
前言:超临界流体具有黏度低、密度大,有较好的流动、传质、传热和溶解性能等特性。
