Overview

      High temperature and high pressure dynamic filtration apparatus is mainly used to test the dynamic filtration of fracturing fluid, clamping the core with the core holder, make one end of the core exposed in the fracturing fluid, make the fracturing fluid shear flow at the core end, at the same time forming filter cake under the pressure difference at core end, part of the fracturing fluid will flow through the filter cake from the other end of the core. Through the experiment the device can determine how the different fracturing fluid system and additives influence the filtration of fracturing fluid. The determination of dynamic filtration of fracturing fluid under the conditions of high temperature and high pressure is the requirement of Laboratory equipment.
