The GGSD71 HTHP dynamic fluid loss tester is a test instrument that simulates the fluid loss of drilling and water drilling fluids in deep wells (high temperature and high pressure). It is suitable for:
1. Static fluid loss and filter cake preparation test: at any temperature from room temperature to 232ºC, the maximum working pressure of the drilling fluid cup is less than 7.1MPa, the filter loss pressure difference is 3.5MPa, and the filter loss area is 22.6cm2.
2. Dynamic fluid loss and filter cake preparation test: at any temperature from room temperature to 150ºC, the maximum working pressure of the drilling fluid cup is less than 7.1MPa, the filter loss pressure difference is 3.5MPa, and the filter loss area is 22.6cm2.
3. There are double screens, which can meet the measurement of cement slurry.
