1. Overview
The instrument is a special instrument used to evaluate the interaction of foreign fluids with rock samples. It is mainly used for dynamic filtration test of fracturing fluid and dynamic filtration test of drilling fluid (mud) on core under high temperature and high pressure. Static filtration experiment of drilling fluid (mud) on core under high temperature and high pressure. Experiment of Core Contamination by Drilling Fluid (Mud) at High Temperature and High Pressure. Core sensitivity evaluation experiment.
During the test of the high-temperature and high-pressure dynamic pollution instrument, the core is clamped by the core holder, one end of the core is exposed to the fracturing fluid, the fracturing fluid does shear flow on the end face of the core, and at the same time, a filter cake is formed on the end face of the core under the action of pressure difference, and part of the fracturing fluid seeps out from the other end of the core through the filter cake.
